95 E320 Wagon Cruise Control not actuating
 

My Car has the ASR feature which I believe determines the typ oe Cruise control system or components are associated with my CC.

When I got a new receiver installed, my CC stopped activating. I tried to get the radio people to figure out what went wrong and they insisted they did nothing.

So that being said what's the best way to figure out what's exactly wrong so I can buy the right part and get my cc back online?

First check is the fuse....

..but, also look at the instructions on the new reciver...some tie into the speed sesnor circuit of the car for volume control.
