Forgive me, in advance if this has been posted, I am having difficulty searching posts (error messages).
My issue is, I was to upgrade my 04 CLK320 with a comand unit from EBAY.
Seller says it will work, but you know how that goes, I asked Benz here and they were not forthcoming almost unresponsive.
Can anyone tell me if this is an easy fit to my vehicle?
USA MODEL
PARTS# A203 827 37 42
SERIAL#BO151926262784
Includes cables, antenna, and used unit for 800.00 (reasonable?) But mostly will it just be a plug and play - as there are no refunds offered.
2004 CLK W209 + Comand 2.0 
Linear Mode
