I just installed my Avic-F90bt and everything works great except for the phone. From the top menu on the bottom left the phone button is not grayed out; it is still white, and when I go to screen calibration that portion of the screen works so idk. It worked yesterday after I finished installing it but when I tried pairing the phone i used the wrong passkey so the 2 did not pair, ever since then It hasn't worked. By the way I by passed the unit, any help would be greatly appreciated.
