All-

Cruise has started working intermittently since I have had the car. Seems to work better when it is cold outside. 2 questions:

Solder or replace amplifier? Can't seem to find a good source for an AMP, can someone recommend one they were happy with?

Are the units compatible with other MB cruise Amps? Seem to remember reading once that the AMPs are the same, the small chip that plugs into the AMP is what distinguishes performance.

Thanks
