I just purchased the 2003 TL . I would like to put in a navigational system. If anyone knows anything about an aftermarket one , I'd like any information. Thankyou! Darlene

 

Garmen...I believe that's one brand out there. try searching

and welcome to the boards....

 

If you have a Pocket PC or palm pilot, there is an addon which turns it into GPS for a just a few hundred. I have it and it works great (3d maps, voice giving directions, etc..using same database as mapquest). Much cheaper alternative, and you can take it w/ u to another car.
