bigunclejethro Posted December 29, 2013 Report Share Posted December 29, 2013 Anyone know if you can add nav to a system that came without it? I didn't want to pay the extra few grand to get it from the dealer, just curious if I can get it aftermarket or put in a new unit that has nav Quote Link to comment Share on other sites More sharing options...
guls Posted December 29, 2013 Report Share Posted December 29, 2013 If you are talking about 8.4 system, it is only few hundred dollar option to buy the Nav version. I do not know if you can add it later. But a Garmin or TomTom is always an option. Quote Link to comment Share on other sites More sharing options...
