I hope that this isn't answered already and I'm just not able to find the thread...
Anyway; I've downloaded the updater from Pioneer and followed their instructions to the T. FOUR times followed their instructions. Meaning, I've burned a CD fourt different times using everything from Windows 7 default settings to three different burners (Roxio, Imgburn, and B's Gold). Using two different computers.
All that happens when I put the disk in the AVIC is that it says CD inserted. Then it just sits there and looks stupid at me. For up to an hour I left it just sitting there. Nada.
