I just started getting an SSR message when I attempt to use the Sirius in my one month old 05 MCS. According to the manual it means that the receiver is overheating.
However it's 50 degrees out and the problem started as soon as the car was turned on.

I felt the receive (but haven't removed it) and it doesn't feel at all warm.

Any suggestions would be most appreciated!

 

Not sure what an SSR message is, but I had to bring mine back 3 months after I got it because of a bad antenna cable. It actually would quit when it got too hot, there was a small break in the cable. When the cable contracted from the cold it worked fine, but when it was hot out the cable expanded enought to not work...
