Hi does anyone have a cd player fitted behind there screen oem bmw fitting on there e53 ? .I am trying to get nav retrofitted in the uk and only can find one guy /company who will undertake the job .that said he is also wanting me to fit what he wants ie mk3.now after reading the posts in here it seems mk4 is the way to go ?? if i purchase the parts on ebay and buy a brand new loom from bmw does anyone know the correct part number as i read the retro fit loom is definately a different part to std piece of loom you would buy from bmw oem ,also if anyone can reccomend a fitter in the uk please advise and cost involved.

I have decided i only want 16.9 and mk4 , no bluetooth no tv no movies , no cameras . just the latest spec satnav with mk4 and latest16.9 ,i want the system hooked up to my 6cd in the boot thats a bmw oem part and to work with multifunction wheel ,a local member ccfj1 has been very very helpfull any more help before i take the plunge would be great thanks paul
