Hello gurus...I just got a Blackberry and was able to bluetooth sync it quite easily with my GO730. On my last trip, I hooked the TT to the aux port of the car...it played music and gave directions quite nicely. The only strange thing was when I got a phone call (bluetooth) I could just barely hear them (seems it was playing through the TT internal speaker. Is there any way to have the bluetooth phone sound go through the aux like the rest of the stuff? TIA
