I found 2 CD Changers that are compatible with my wife's '95 C280 on Ebay. One is advertized as an Alpine CHM-S630, CD Changer (M-Bus), and goes for $142.49 plus $30.00 for S/H.
The other is advertized as a Mercedes Benz CD Changer for "94-"95 C280 with 10-Pin connector, also manufactured by Alpine but goes for $219.95 plus 16.50 for S/H. Both are a lot cheaper than my local audio shops, but I also want to make sure that I'm purchasing the right one.

I was wondering if anyone any insights or recommendations as to which one I should go for. BTY, there is a connector in the trunk that is on the drivers side of the car.

Thank you,

Bertrand
