I don't know about a backup voice, but the backup beeping is a dealer set option. The dealer can change the constant beeping to one beep when backing up.Does anyone know how to disable the annoying backup voice? I can't find the answer in neither navigation setup nor front panel setup.
If you have NAV, I think that you can set it yourself. I don't remember exactly how to get there on the NAV screen, but it's pretty self-explanatory.
After having the seat belt beep go off yesterday when all I had was two bags of groceries (granted they were two heavy bags of groceries) in the passenger seat, I decided that I want to get that alarm turned off in my car too.Why the need to disable the seat belt beep? Do you drive unbelted or do you sometimes have big heavy objects in your passenger seat?
