Just installed a Dynavin unit into my M3 and got the old widescreen unit that I want to sell. Other than the actual unit what else should be included with the sale for buyer to be able to use it and rough price to ask for? Out of a 2002 m3. Thanks 
from memory might have one scratch on the screen, will have to have a proper look. ive just put it in the box.Is the screen in good nick?
Man things are getting cheaper. I paid $1600 (CD) and $1200 (Tape) back in 2004 for mine.
pretty much, everything in the passanger side behind the boot trim is useless now. get rid of it all. everything will be labelled. you should have the tv tuner, nav computer, BM53 unit behind it.i got the tape one.
do you have pic of the business radio module or where do i find it..
is there anything in the boot that i should take out to sell (cd stacker is gone already).
i do like the dynavin. just got it so am still learning to play with it. i got an iPhone 4 and the address book doesnt seem to work so i gotta dial out of phone which sucks.
what about you??
