Please Help! Ok so im a cheap !Removed! and didnt want to buy the new updated navigation dvd for my 06 gs 300. I went into the dealer settings and attempted to download a different map pack. Once i did so, my screen says please insert correct disk with chinese or korean symbols underneath it. I can get the disk out, but this screen will not go away. Anyone know of a master reset? Everything else is functional but the navi.
