I have an 04 tsx without navigation and I would like to get one installed. Is it possible to put a factory navigation on a non-navigation car? If so, how much will it cost me? Thanks.

 

Do a search and you'll soon find out it will cost more and be more of a headache than trading your car in or buying an aftermarket one.

Yea... it's a HUGE pain. Just like trying to convert auto in manual. It's not worth it.
Better off either trading it in for a navi, or buying an aftermarket one. (which there are some really nice after market ones. )
