Need to figure this out F90bt with unofficial 3.0. Thanks guys

The only thing you can do with BT and the phone with the F series is transfer contacts and make calls. Other then that you need to be more specific on what you are asking because what you asked didn't really make any sense.

Sorry if someone calls me on bluetooth and gives me a address over the phone. Can I enter the address into the nav to find the address will im still on the phone without having to write it down. Then hang up and switch to the nav to enter my destination and start route.

No, not on the F series. You may be able to do this with the 3.0 software but I can not confirm. You certainly are not able to do it with the F series 2.0 software..

I have 3.0 and can not get it to work.

Then it is probably not supported. The folks over at the X series forum could probably verify that for you though. Just search those forums to see if that question has been posted before starting a new thread. The X series is the F series 3.0
