I'm close to reaching insanity... I redownloaded the v27.1 version and purchased 3 different CDR packs (Verbatim, TDK, Sony).. I burned 10 CDs at 1x and 24x speeds... when I inster them into the DVD unit in the trunk same thing happens.. I mean nothing... the display still says Please insert a navigation CD/DVD.

I also copied my Dvd Nav on a DVD+R... the unit will NOT use it if I insert it in. It's like the MKIV I have will not read ANY burned CDs/DVDs... please help.. it seems I'm the only unlucky guy

Thanks a lot!
