Galaxy mk2 Multimedia System

[hyperjase]

I recently bought a 2003 1.9 TDi Ghia with the DVD Multimedia system fitted but it doesn't work (suggestions as to what to try welcomed!) So I'm currently looking at whether I can use the headrest monitors and tap into the wiring with a different DVD unit. I've located all the wiring and both 12v feeds and ground appear fine (monitors don't power up when I point remote at either screen) 

It appears the radio has been changed out at some point, the date on the unit is 2008 so is a post-fit. Maybe this is why it doesn't work? There is a 12v feed from the radio to the DVD unit, I've checked that much it appears there's an issue somewhere.

Many thanks,

HJ

It actually appears I never asked my original question!

Does anyone know what the wiring assignment is for the headrest monitors?

[Chrispb]

Hi and 
All I can tell you is you need the radio switched on to use the DVD, there may be more than one feed to the DVD which I'm sure Mirez will be able to confirm for you.

[hyperjase]

Thanks for the welcome Chrispb, I did spot on another thread about unplugging the left monitor, I'll try that in the morning. I'm really hopeful that it may be sometime that is sortable.

[hyperjase]

I've tried unplugging each/both monitors and still nothing -- it's dead. 

I'm going to try to see if I can fire up the monitors individually to get a video display on the screen, if I can do that then I'll work down that route - it looks like the Visteon system is dead (but if anyone has a control module they are interested in selling - I'm interested!)

Many thanks.

[Mirez]

Hello and welcome

The system has its own 12V and ground supplies and also takes a switched input from the radio to tell it the ignition is on. On factory installations then this comes from the 6000CD (or equivalent) only when the radio is physically turned on - a mistake a lot of people do make.

The monitors unfortunately use a proprietary AV signalling route so it's not easily possible to drive them with anything other then the visteon unit. Check you have both 12V feeds and the ground first. From experience it's also vitally important that the controller (the big silver/black box behind the middle control panel) see's 12V first and then ignition 2nd. If it see's them at exactly the same time or the ignition first then it throws a proper wobbler and refuses to do anything. The only recovery for this seems to be force feeding it 12V on those two lines is random sequences!!!

Finally, the same unit is also used in the Ford Mondeo and Volvo Something-or-other so you might get a few more hits when part searching using those two as well!

[hyperjase]

Thanks for that - as far as I've been able to tell there are three wires - one 12v constant feed, one 12v from the radio power and a ground - is there another power source I'm missing?

[Mirez]

No thats the 3. The feed from the radio is the switched one which the unit must see after it has the permanent connected and not before. What radio is in the car now?

[hyperjase]

It's a 6000CD - it has 4 connectors total - one for the CD changer, 1 for power, 1 for speakers out and 1 in between with 1 wire which I have no idea what it does...

[Mirez]

That wire is the VSS (speed signal) for auto volume.

Is it a round or square edged 6000? It should be a square edged version (thus fitting perfectly in the dash) - have you measured the voltages at the radio and media center?

[hyperjase]

I've attached a picture I just took - one thing I've just noticed.  I turned the lights on and the DVD unit didn't illuminate.  I've tried putting the ignition on then turning the radio on but nothing - still dead.  Could the issue with the illumination be that there's no power going to the unit?  I've done a lot of searching around about info regarding this.  I've checked the power to the rear of the DVD unit and I did find all 3 power supplies were working there (+12v, +12v radio & ground).[attach=1]

[hyperjase]

I have also checked all 3 points prior to the DVD unit/module - all 3 are fine, I did a check on the Radio too and all appeared fine from that end (I managed to trace which wire goes from the radio to the dvd as it is the same colour stripe on the wire)

[hyperjase]

Checking on your post here (https://www.fordmpv.com/smf2/reference-library/galaxy-radio-connector-pinouts/) - pin #3 appears to be the one that feeds the DVD unit - Brown with a Red stripe.  It says on your post that it is not connected - is that correct?  Or does it double up as the +12v output to the dvd player?

[Mirez]

Its pin 5 thats not connected, pin 3 is the permanent supply. Pin7 is the switched supply.

[hyperjase]

My apologies, I looked at which pin was where and got it wrong - pin #3 confirmed as +12v permanent (the one that goes to the same connector that feeds the DVD unit).  I went out to re-check everything.  I get the correct voltages from the wires behind the radio and also under the driver's seat where the connector is. Everything confirmed as good going to the DVD unit.  Still unsure about the illumination though - that appears to be dead (nothing lights up on the front of the DVD).

[Mirez]

Connector under the drivers seat?? You 100% you got the right connector?

I think you may have to remove the center console and take a look at the back of the controller to be sure.

[hyperjase]

There's three connectors under the drivers seat, one power one (3 pins), one up to the headrest and another I'm not entirely sure what it goes to.  I don't think I have stumbled across the airbag connector - I'm trying to discount that one!

I'll check behind the dvd player tomorrow about if there is a constant 12v, radio 12v and ground. Assuming they're present and correct is there anything else I can check?

I'll grab pictures of the connectors I mentioned above.

[Chrispb]

Just had a thought here are you checking the voltage at the unit with it connected to the unit, just in case voltage drops to zero when connected.

[hyperjase]

Just had a thought here are you checking the voltage at the unit with it connected to the unit, just in case voltage drops to zero when connected.

Earlier I tried with it disconnected but I'll check tomorrow with it connected - but when I probe the connector under the driver's seat, the 12v remains for a few seconds before dropping down to around 1v slowly dropping to zero. The constant 12v and ground remain.

[Mirez]

My concern is that I've never seen a connector under the drivers seat for RSE supply! Normally, you'll have a blue connector under each seat for the monitors and then a yellow, screened, one for the SRS Airbag system and finally a black one for heated seats.

I know some cars had the RSE system fitted after ordering by the dealers but I've not worked on one -  if it is a power supply plug it will likely be a 4 or 5 pin connector as illumination supply and ground are often seperate.

[Chrispb]

Would it not be best to probe/test lamp the actual DVD player, and just to warn you inadvertently probing air bag system could cause unexpected deployment.

[hyperjase]

The odd thing is, this 3 pin plug (there's actually 4 pins, only 3 wired in) - when I probe that the accessory 12v works from the radio on/off.  I've grabbed a couple of pictures:

[attach=1]

[attach=2]

The second shows the connector I'm talking about - as far as I can see (and having pulled the cables confirmed) - these go up to the DVD module.  The blue one goes up to the screen and the third I have no idea what this is ... lots of wires and I haven't checked this connector yet.

Hope this sheds some light on things.

I haven't come accross a yellow one yet (thankfully) and ours doesn't have heated seats but does have these two extra connectors.

[Mirez]

Question, if you put your reg into ford's etis system does it show that it came with the RSE system?

The black plug looks suspiciously like the heated seat one, the blue is the monitor and the black will be heading to the back of the car for the VCR player. Given your car is a 2003 then it should have come from the factory with the VCR system and not the DVD player (introduced from 2004 IIRC) hence my question.

I've tried entering my reg on the ETIS system but it crashes - so can't tell at present.  I'm not entirely sure about whether this was fitted post factory fit - I haven't seen a VCR as of yet (where would it be if it were still installed?)  The one confusment I have is that the small black connector does power up a 12v source from the radio (when it's powered on) - hence why I've spent so much time looking at that connector.  Is the second larger connector the one I should be looking at for power input?

[hyperjase]

PS - the date of manufacture on the bottom of the DVD unit is 2003 - prior to when the car was registered as new.

[hyperjase]

Just managed to get into etis - some interesting info:

Multi-Media System Less Telematics
With Family Entertainment Sys - DVD

So it was all factory fitted - but not sure what Telematics is?

[Mirez]

Well there you go, learnt something new as I didnt think pre 04 had DVD systems!

If you'd had a VCR it would have been in the tailgate storage box.

[hyperjase]

I've definitely not seen anything in the boot - this will also be confirmed by the etis data.

So the next question is which connector should I be checking?  The large black one or the smaller black one?  I know the smaller one provides power but I have no idea what the larger connector actually does.

[Mirez]

Your setup is completely different to any other I've seen - I think you have to see whats going on at the back of the dvd and controller.

[hyperjase]

I shall check the wiring tomorrow- what colour wires on the rear of the DVD? Also which connector on the module and any idea on which wires there? The module is the grey area for me.

[Chrispb]

I wasn't gonna say anything coz I thought you'd have it sorted but I had a look at ours today there's the two sockets on the DVD but the controller has four, I know that's not much help but what I did notice there is a 5 amp fuse in the back of the DVD.

[hyperjase]

I've spotted the fuse before and have made sure this hasn't blown, but tonight when I test things I'll check that just in case it has blown in the meantime.  I'm intending to check voltages on the DVD unit - but not entirely sure where the voltages are on the control module.  But I'm also planning to test continuity of certain wires to make sure none have a break in them (mainly the small black connector under the driver's seat and the cable from the radio to the control module).

As soon as I have any results from voltages and continuity I'll post my findings here - I am sure this system is dead, it's just if I've overlooked something.

[hyperjase]

Rightho - think we may have an/the issue here.  I've pulled apart the system, tested voltages and what power goes where.  Here's what I have:

Looking at the DVD unit (this is upside down) - I probed the Grey, Red and Pink wires.  I found a few weeks ago the German fitting manual for this system which shows the pinout for the rear of this unit. 

Pin 8 (Grey wire) = Ground
Pin 6 & 7 (Pink wire, fed in to Pin 7, jumped to Pin 6) = Ignition 12v/Illumination
Pin 4 = Battery +12v

I've checked pin 8 and 4 and all is good there - I get a good 12v feed.  Pin 6/7 shows +1v (regardless of radio turned on or not) - I've tried jumping a wire from Pin 4 to Pin 6/7 - the illumination shows on 2 buttons on the DVD and the screen backlights come on - nothing else works.
[attach=1]

This is the side of the control module.  The left-hand connector is where the DVD is plugged in to, the centre connector is where the power comes in (from the odd 4-pin connector I pictured in a post above).  I have checked that 4-pin connector, I get a good +12v, ground and radio +12v feed. 

On the connector on the side of the control module, the black wire (which you can just see on the left of the connector, behind the red) is the ground.  The red wire is the +12v feed.  The white wire (far right of the connector) is the radio +12v feed.
[attach=2]

Now - the two green connectors are changeable - either plug in either connector but as far as I know this should be right.  But - the all-important pink wire appears to be in an odd place.  Looking at the position of that wire, the same on the other connector is orange. 

I got a touch confused here and I'm not 100% sure what the white wire voltage was. 

But I also saw a different forum post regarding the pink wire (pardon the off-forum link) here - http://www.fgo.co.uk/forum/index.php/topic,8510.msg168630.html#msg168630 - check point #7 which discusses this pink wire.  I've tried jumping it but I haven't tried jumping it at control module level (on the image it's the right end of the connector that has no wire in it).  Not sure if that would help - it may fool the unit into working (as that user found).

Other than that ... I'd be looking to find another control module in the hope that is where the problem lies.

[Mirez]

Humm, can you upload a copy of that fitting manual. Could be interesting.

1V certainly isn't right, chase the 12V switched wire and see exactly where it go's. At this stage I suspect something is pulling it down to ground although you would see this back at that 4 pin connector which makes me wonder if its fed from somewhere else.

Again, if its not seeing permanent and switched supply in the right order then it won't do that much so I wouldn't rule it out as dead just yet. I would be inclined to unplug the 4 pin connector under the seat and then run myself a feed and ground from the front lighter socket direct to the pins as needed. You'll rule out the radio supply and know exactly what feeds you have then.

Hope they're of some use.

I've tried what you suggested and that didn't work - but I'm still confused as to why the +12v from the radio goes IN on the white wire but on the connector from the module to the DVD player, that pin on the connector doesn't have a wire - but when I probe it, I get the 12v feed.  The Pink wire still only gets +1v.

When I jump the empty pin from the DVD connector to the pink wire, I get the screens lighting up and front illumination - but nothing else.

[Chrispb]

Can confirm today power supply comes in on the centre green plug, I also get the 1 volt on the pink wire up to the point where I power it up then it becomes battery voltage.
I must admit the wiring for this is a minefield but have to agree looking like faulty controller.
Also the unit lights up when powered up not when side lights are switched on.

[hyperjase]

Well I totally gave up with the factory fit system, too expensive to find and replace parts so I went down a different route.

I wanted to change it all out but (being darn fussy) didn't want to change the headrests to those tacky leatherette type ones.  So I began eBaying for what I needed.

I removed the screens from the headrest (remove the plastic surround, then remove the screen and pcb) then keep the existing wiring to save all the messing around when wiring the new system back in.  I hit one problem here - finding something that would fit in the same area as the old one (the old one is around 8-9mm thick).  So rather than buying a screen within a case, I managed to track down just a panel and a board that support phono video input.  So I found this at a very reasonable price (http://www.ebay.com/itm/VGA-2AV-lcd-driver-board-7inch-800-480-AT070TN93-EJ070NA-03A-3mm-thickness-lcd-/181141710839?ssPageName=ADME:L:OC:GB:3160) - I ordered just one to make sure it worked fine.  Quick delivery from China too meant I was able to test quickly.  The screen is just over 1mm thick, a lot thinner than the stock so I got some single sided foam and padded the back out so when pushed in it sat neatly against the plastic surround.  I found to my cost the back of the screen panel is conductive and needed a second board (which the seller sent me very quickly).  Couple of handy features.  1 - there are buttons on the board but once you have it set up, just remove it and there's no need for any button control as (2) when it gets power AND a video input it automatically fires up!  So all I needed was 4 wires, two video and two power (which I just used from the existing wiring loom).

So that's part 1, the screen fitted.  Then I looked at the DVD player itself.  I bought a dirt cheap DIN sized player that I could test this all with and that worked fine, I placed it under the driver's seat and managed to play DVD's with no problem.  But being the perfectionist I like to be (I wish!), I wanted to find something that would fit where the original player sat.  So I measured up the unit and found it's virtually identical to 3/4 DIN size.  So I managed to find a cheap-ish player on eBay (http://www.ebay.co.uk/itm/Veba-AV2706-Car-CD-DVD-VCD-DIVX-Player-USB-SD-MMC-MP3-Stereo-3-4-Din-/350920982288?ssPageName=ADME:L:OC:GB:3160) - this took longer than the screen did to arrive(!).  Now it does almost fit in the same gap (I'll need to remove around 2mm plastic either side of the console) but it's near as dammit the same size.  Only issue I found with that is that it only resumes playback on DVD's and not any media files on usb/sd or DVD.  But I can live with that.

So that left one final problem.  Hearing the damn thing!  So I got clever on this one, determined again to re-use the equipment provided, I remove the headphone unit and cut the connector off the other end, leaving just bare wires.  I then plugged in a 3.5mm jack plug to 2x phono plugs - then continuity tested each channel (left, right and ground) until I'd determined which wire was which for the output.  It turns out all the ground outputs are on one wire anyway, so I had one ground and 4 left/right outputs.  So for the original unit I tested I just put that on the speaker output from the DVD, that worked perfectly well but on the new unit the audio is phono output and while it has a volume control it doesn't really have any pre-amp so it's very quiet even when turned up full.  So the final piece of the jigsaw was some form of amplifier - but when I eBayed this I kept getting the big-ass amps which power sub-woofers etc.  So I changed my search term slightly and found PCB versions which are bare-bones but able to fulfill my needs (http://www.ebay.co.uk/itm/AC-DC-12V-Single-power-supply-TDA2030-amplifier-board-2-0-dual-channel-TDA2030A-/160969069448?ssPageName=ADME:L:OC:GB:3160).  This arrived today and a quick trip to Malpins to buy a mounting box, I have now created a simple amplifier which I can power from the radio-on power and I've wired the input and outputs as phono so it essentially becomes in-line.  I haven't fitted this yet but I'm confident it's the final part to make this a fully-working system.

And on the plus this cost me Ã,£135 (would be Ã,£170 for both screens) to fit!

[Mirez]

Sounds fantastic! Any photos?

Whats the plan with the old setup? Did you discover what was at fault in the end?

[gregers]

 

[hyperjase]

I have one last problem now ... I think it's a grounding issue, two possible solutions (I think), one to ground the Amp to the chassis somewhere, a good earth point or fit an inline noise surpressor.  I'm hoping finding a better grounding point would do the trick but I have no idea where I'd find one near the centre console -- can anyone suggest on that?

Here's a few pics from my project:

• The mod to the headphone output unit : https://www.dropbox.com/s/gyuk6r2cv6p0f34/2013-12-29%2012.21.21.jpg?m=
• The wiring loom butchered to provide power input and use a spare 4 wires on the loom up to the headrest : https://www.dropbox.com/s/zqn7k3e5e2httsb/2013-12-29%2012.21.46.jpg
• My 12v amplifier mod (the board fits exactly inside just leaving the volume control outside - I also wired everything outside the box - turned out there just wasn't enough room) : https://www.dropbox.com/s/q7l11jy0xm3nude/2013-12-29%2012.21.52.jpg
• And finally, what it all looks like, before refitting into the console : https://www.dropbox.com/s/ao656z6tylmnfsu/2013-12-29%2012.26.00.jpg

Just this last issue with the DVD motor noise to eliminate then I have a perfect working system

[Mirez]

Looking forward to seeing it all in situ - looks great!

There are two earth points, one under each of the front seats, where you can ground stuff to. The factory RSE system is grounded to the passenger side one anyway IIRC

[Mirez]

Great stuff, thanks for the pics - looks like the driver's side will be more accessible, hopefully this'll stop the motor interference!
