hi, i had reboot problem too, i tried to fix, it just didn't work for me. i think i made it even worst. gps and music doesn't even work now, when i go to check the version screen, gps nav was like no version number at all. i think i deleted some fatal file or something..... so i was wondering if i bought the software update 3.0 from pioneer. will that fix my problem? thanks in advance
