In Nov. Iinstalled the new 3.70 update DVD disk on 04 TL. Until today it has been working fine. My problems occurs at start-up: The OK button along the right side doesnt not appear. Also, the following messages appear:

DVD NAVI ERROR
DVD NAVI CAN NOT READ DVD

I have also tried MAP/GUIDE, MENU, CANCEL - download proceedure but still the problem persist. The Navi DVD is NEW condition and no scratches.

What gives? Look forward toward the replies.

Thanks,
Nick
