Just bought a 2007 TL and how do you reset the handsfree??? Says contact dealer, but please!?!?! HELP!!??!!

 

I think you need to enter the security code for the system. When i disconnected my battery, i had to enter both code before my HFL, Navi or radio would work. If the sticker isn't in your manual, you will need to go to the dealer to get it reactivated.

Not sure this is your case though....

 

or you could try common codes like 1234, 0000 it worked on mine but i bought mine from a used car dealer that did not have this info.
