WOW... check out this site!!! I've had an AVIC-D1 since it was the current model. I've upgraded the maps each time and I'm running the latest version. Not the CNDV-90MT that was just released but the previous... 70MT I think.
Anyway, I can no longer use my unit and haven't been able to for many months because the keyboard is not aligned right to enter addresses. I have to hit the letter that's next to the one I intend to key. For example I need to press the G button to get it to enter F. I can't press the letter keys to the side because they're off the screen. Sometimes I can get it to type the key if I take a Bic pen and press the extreme corner of the unit's LCD by the letter. It's basically useless and I've been using my iPhone. HOWEVER, I'd LOVE to figure out how to fix this issue. AM I OUT OF GAS?
I SURE hope this problem has been experience before and someone knows how to fix it. Perhaps a full system reset or something... I'm not sure how to do that so instructions would be great. Anything.
Very glad this site exists... the Internet rocks...
