I just got this in the mail for my TP2:
http://www.amazon.com/FlexSMART-Blue...6838968&sr=8-1
To get it working, I had to enable bluetooth, put the transmitter in pairing mode, then connect to the transmitter, going through 1-2 menus to finish up and back to the home screen.
That just seems like a lot of time spent each time I get in my car. Is there a way to do this faster?
