Had to make a sudden trip to FL last month without the RV, so I moved the SG into my '00 Chevy Silverado six cylinder. Radio started resetting its self just before I left and the full 6K miles I drove.

Thought I had a loose ground or something on the radio.
After getting home, I was searching for known problems with the SG, not thinking about the radio, and lo and behold, up popped a problem with Chevy radios randomly resetting when the SG was installed!!! Have not removed it, or driven the truck since getting home, but will unplug it next time to see what happens.
