Does any one know where i can locate the factory oem 07 navigation setup for my TL

 

well, it depends, if you want to do the conversion from non-navi to navi, you can find a bunch of parts on ebay for cheaper prices or sometimes you can catch a good dealer here in the blackmarket section. The hardware brand new from a dealer can add up to over 2K, but the ebay route or blackmarket will save a lot of money.
