Has anyone ever put aftermarket navigation in their cars? And even if, can I get some advice? I was thinking of putting an navi system in the SC as own Christmas Gift, so I wanted to know if anyone could help me with that. Advice? Opinions? Experience? Pricing? Etc etc

Thanks

 

are you for real?
tons of people have put aftermarket nav units in their cars.
use the search function and you will get a lot of info on the aftermarket navs; prices, pics, experience etc in our cars.
i am in the process of installing an eclipse nav unit in my car now.
good luck
