Title: Mfd reverse camera
Post by: gazz1970 on May 30, 2014, 09:10:12 PM
Hi all I have the mfd nav unit Fitted and I'm trying to fit
Reversing camera. I have fitted the camera thro the multimedia
Interface, when I go in reverse the picture comes up for 2~3 seconds
Then flickers erratically for 5 secs then comes back and so on. Tried
The camera thro a stand alone monitor and fine, anyone any ideas?

What type of multimedia interface (MMI) is it and where did you power it from?
Most of them have a cheap controller which requires a VERY good power supply, else it will hunt between PAL and NTSC (which causes flicker on the MFD)

If you pop the cover off the MMI you'll probably find a small (normally blue) potentiometer near the power cables - With the engine running (as you'll need the alternator voltage) give that a tweak and it should correct. You'll need to move it ever so slightly!

Hi Mirez  I have tried powering up from a few different places to see if that made. Difference, the multimedia unit came with the mfd unit I got off eBay to replace mind bout a year ago just got round to fitting the mmu, tbh got sick of the mfd display going blank when I reverse. If memory serves it was yours Mirez

Ahh fair play then and probably was a year ago! - Lazy sod :)

If you pop the cover off the MMI you'll find that blue pot I was on about, give it a gentle tweak and you should find it sorts that out. You might want to pop a drop of glue on it after its set as pots have a habit of moving slightly with vehicle vibrations.

Alternatively, you could remove the reverse feed into the "VID ON" pin - that's what turns the MFD to the reverse camera.

Not really, I had my own fusebox in the cabin direct from the battery which had that unit on. You want a circuit that's not going to fluctuate much or has little use...

Good choice :)

That's a 12V switched supply which is nice and stable, where I took mine from as well :)
