from an earlier thread:
MBenzNL said:Retrofitting comand in a W211 IS possible BUT there is a big difference in the audio systems between several 211s as in:
- US spec versus euro spec (australian spec equals euro spec btw)
- 211s manufactured up to 01/03/2003 and 211s manufactured after that date
- 211s with(out) H K soundsystem
I am currently retrofitting comand in a late 2003 W211 (which stagnated due to the audio main wairing harness being in back order) which has the less ideal setup to start with and requires a complete change of the audiosystem...
In cars like this one it is not really worthwhile retrofitting comand in when looking at the prices for parts alone...but depending on the audio set up in a W211 comand retrofit might be affordeable - and certainly is doable.
MBenzNL said:Every 211 that has a separate audio gateway (pre 03/2003 and HK equiped cars) are easy...
