Probably going to get flamed for this but (I did search and still am searching)...
I am just looking for clarification on what part number or specifics I would want to look out for to switch my factory Audio 20 head unit to a Comand unit? I think I read probably ten different threads from searching on here and googling and can't find a clear cut answer. I do plan on making a concise review on my YouTube channel on this install and what is required once I figure out for sure if that entices anyone...As I can see from searching this is a recurring and somewhat muddy topic.
From looking on Ebay some of my confusion is the difference between parts numbers ex:
Is one more easily compatible than the other? Is there any modification needed to wiring or components that I am missing or would need for everything to work properly?
I honestly don't remember the difference between the two, but I do remember both of those part numbers.
The only other thing I can remember is you will need a GPS antenna (with the blue connector I think). You can buy any aftermarket one that should cost around $20.
$200 is a great deal; these used to go for $800 from the junkyard, albeit a decade ago...
The A 203 870 picture matches the unit I installed some years ago. As mentioned you need the antenna, plus a new wiring harness. I did my swap with the help of MBenzNL at the time. I do remember him supplying me the unit, wiring harness and antenna. Mine was meant for 2007 models that never ended up coming to North America as C55s, but I believe did as C280s, etc. Unit was referred to as MCSII v2 which included MP3 functionality.
Ok, thats what I thought as far as wiring goes. Thanks for clarifying! I'll be on the lookout for a good one and might scout my local german wrecking yard before going Ebay. Detailed install and review video would follow.
