I have a 2003 TL Type S, and I was wondering if its possible to install a Navigation System after the fact?

 

I replaced my HU with Pioneer AVIC-N1. There are other options from Alpince and Eclipse as well. I hated the Bose system in the car so, I also replaced the speakers and added two amps. But you don't have to go that far. If you simply want to add Navigation capability, I would recommend this solution.

 

Porshah: Thanks so much

 

No problem. If you don't like the AVIC-N1 which is single din, you can wait another month and get the AVIC-D1, which will be a double-din. I had the Eclipse in my car first, but the HU was giving me trouble so the installer agreed to give me the AVIC-N1. Now I am thinking about getting the D1 installed, because I am not sure if I like the Single-din with the motorized screen.
