I just bought an 05 TL that didn't have the Navi. I found someone selling the dash unit part pretty cheaply with climate controls and all. But what I am wondering, what exactly would I need to put in the stock TL Navi? Such as what wiring harnesses do I need? Do I need a new antenna? If someone had a list or could come up with one that would be great.

Thanks!

 

You can only go aftermarket on the NAVI's. If it wasn't installed at the factory, i'm pretty sure you cannot have a factory NAVI.

 

true the navi is integrated into the whole car harness and conversion would cost a lot of money/time
