I did a little search through NAM and didn't find this one.
My stock radio (I have the IPOD adapter, but I've never used it seeing as how I do not own an IPOD) has started randomly changing channels when I start the car. Here are some examples-

Last station before turning the car off- OPB Radio/ Station when turning car on- KINK FM
Car off- KNRK FM/ Car on- 620 AM (so it will switch from FM to AM)
Car off- KNRK FM/ Car on- 630 AM and all of my preset AM stations have disappeared
Car off- OPB Radio/ Car on- CD player

Has anyone else experienced this? Sounds like an electronics problem maybe? I'm not very techno savvy with this kind of stuff, so if you reply please keep it simple.

Thanks!
