I have the telephone button on my nav, i hit the button it bring up the dial screen, directory, contacts, recent calls etc. How do I link this to my phone? Also in the settings it wont allow me to turn bluetooth on...i select on and it stays on off.

i think your missing the bluetooth tcu. i have one that is just about brand new with the passkey for sale. let me know if your interested.

the guy who you bought your car from probably took it out and installed it on the other car that he sold before yours
