I want to put nav in my 02 max. Can I buy the nissan unit and install it in my car so its a factory look or do I HAVE to go after market. Any help is much appreciated.

If I can go with the factory look what exactly do I need beside the nav unit

 

I was wondering whats the difference between factory and aftermarket navis, and i heard you have to pay a couple dollars monthly to use it?

 

this must be one of lifes great mysterys

 

....................get aftermarket...or build your own carpc and you don't pay for using gps....
