I don't know if I'm missing something, but I've looked everywhere. Whenever I change settings in the PCM like the bass/treble or the map orientation etc. it's never stored. The next time I go to start up the car it's back to the defaults.

I can't remember it behaving like this before, but recently the dealer had to replace the PCM because they tried to do a software update and it froze in the middle. So I got a brand new one. I also got a new key to replace one that was broken. The key works fine to start the car, unlock it, etc. I just can't get any settings to stick.

Any ideas? Any settings I've overlooked? I couldn't find anything in the owner's manual about it.
