I also purchased the AUX input harness that allows you to connect an external audio device to the head 
unit, like and iPod or cassette player (since the COMAND unit does not have one).  The part number for 
that is A203 540 6107.  Below is a picture of it (left) with the shortened mating connector harness (right) 
ready to put back into C2. 

 

 
I also purchased the GPS antenna coax cable and a GPS splitter to tie into the existing GPS antenna that is 
attached to the upper right side of the rear window.  I have seen that other folks (including Steve) add an 
additional antenna under the dash when doing COMAND installs but I wanted to make my install as 
“stock” as possible.  Intuitively the rear antenna should work a little better as the line of site around the 
vehicle is better … plus the parts are cheaper than buying a GPS antenna, although more work to install.  
The splitter and coax cable may already be installed in later ’01 and beyond models, but mine was not.  The 
part number for the GPS antenna cable is A203 540 7006 and the part number for the GPS antenna splitter 
is A210 820 2489.  They look like this: 

 

 

I also purchased some C2 connector pins so I could shorten the AUX harness that came with the adapter 
harness.  The part number is A008 545 5526 and you need at least four of them assuming you do the install 
as I did, at least five more if you don’t use and modify an adapter harness.  Buy lots, they are cheap!!
