You know, of course, that your phone must have the Bluetooth HF ability.
If so, it's a simple matter of reading the phonebook instructions and
the TL owner's manual to "pair" the two. You don't need a dealer to do
it although I think most will help you, gratis.
I have an '05 TL and a Motorola/Verizon phone and both work perfectly.
I get a dashboard display of signal strength, battery strength and the
number I am calling. It automatically links everytime I get in and start
the engine. The only hassle is having to manually enter each phonebook
entry into the TL. It will hold 50 entries.
You will love it.
