W209 Upgrade to Comand 2.0 Wiring ?

[maestro89]

I purchased a Comand 2.0 unit (A203 827 37 42) to replace the stock radio (A203 820 25 86) model CM1330. One of the square wiring plugs used with the old radio does not fit the new comand unit.

The system lights up, etc, but there is no sound at all, I am assuming the unplugged block is the problem.

Has anyone else put in a Comand unit in their W209 who can advise me on what needs to be done, what adapter, etc...

Thank you, in advance.

Thank you, in advance.

You will need a replacement plug/connector with new pins for the connection
Did You hook up a speed signal ?
Do you have a GPS antenna ?

Without the above the comand will not work
