Thanks to Stu and others that have put bits on here about fitting a DVD player to the MFD2, I managed to get everything working piecing all of the info together.

I have fitted a half din DVD player (£25 ebay) in the boot of the car above the CD changer, one of those not so cheap multimedia interfaces (£69 off ebay) from Poland. Both DVD and interface have +12v and ground noise supressors fitted from halfords £8.49 each .

All resulting in a great picture and sound, until...... I turn any lights on, especially the factory xenons or the auto light switch, which results in an almost unbearable interference whining noise.

Do I need to fit 3 RCA line supressors? I cant see anywhere else to fit supressors :S Or is there something else I should be doing?

Anyone got any experience of fitting these and getting them to work properly all the time?

EDIT:

Also I have two wires left over as the AV input was populated for the aux in from the jumbo box, which I have moved to the green plug along with my BT kit. I havent connected them to anything and everything else seems to be working fine. Are these important for anything?

Sound to me like an earth problem but I could be wrong......

I had to fit a noise suppressor to the RCA lines, the power supply to the video adaptor box and the DVD player to kill the hum. I also made sure not to run the A/V cabling near any car wiring, I also used good quality shielded RCA cables.

Cheapo power supplies will not help matters, the £25 ebay DVD player is probably the main culprit.

Even these measures didn't stop the high pitch hum from the xenons, it was at its worst when they first ignited then the hum settled down until it was barely noticeable once the xenons had warmed up. The high frequency and high voltage produced by the ballast packs is the cause of the hum.

Thanks, I have actually put my TV from by dining room in my car (on a 12v-240v inverter) and it would work no problem, no noise or interference. The dvd player retails at over £100, just managed to get it cheap.

I think the multimedia interface is the culprit to be honest, I have noticed that it also changes its mind from PAL to NTSC formats as it pleases, might have to contact the guy who is selling them on ebay.

On the other hand, I can only watch the dvd player while the car is stationary, so having the lights off wouldnt be such a problem, until the little one wants to watch dvd's on the move, and I have got some rear screens, thats when it will be a problem again.

food for thought!
