I got an navigation plus 8e0 035 192
brought it to an audi dealer and they said they couldn't unlock it because it wasn't communicating with thier data base. Unit worked fine in my brothers car but when i put it in mine it went into safe mode.

tried some codes now it says to wait 60 minutes but when it goes down to 30 it turns off. i turn it back on and it says another 60 mins. I don't want to spend $300 us dollars and find out i still can't use the unit.

does anyone have any thoughts on how to get the unit working again? if i order the vag com will that help? if so which one should i get?
