this is prob a stupid question...but how do you delete a phone from your AVIC Z1????I upgrade from a razr to a blackjack

i'm sure its there in the menu but you can also delete the avic from your phone

you have to do a reset but you can have more than 1 registered phone.

well the old phone is dead and no longer working

It doesn't matter, if you want to get rid of one phone, you have to wipe out all of them and a few other things in the process. I can't remember which one, but they are on page 175 of the manual. I think it's a level 3 reset to remove phones from the Avic.

I'm really surprised they never fixed this in any of the updates, BT or Z2.
