Last night I was playing an older CD when the CD400 system shutdown and the display said it was "overheating" Has anybody had this problem and or can explain this problem. I waited 15 minutes and it went back on.

 

Playing Heatwave from Martha Reeves and the Vandellas has that effect...lol. Sorry, no idea but you did say "older CD"..

 

Great Glad I joined the forum

 

Good one Savannah...
The fix is to bring it to the Stealership and have the HVAC module reprogrammed using SDD. While you are there we will proceed to *** rape you without vaseline because we can.
You could try bringing your vehicle to an independant shop to diagnose this, but there is a good chance they will have no clue what to tell you.
