I have navigation now, do I need to purchase the navigation option?

Navigation is not a separate module - it is part of the SYNC module (APIM). If you want factory navigation feature (irrespective if you did or did not have it before), you will need to purchase our kit or replacement module with the navigation option. If you do not care to have or retain the factory navigation option, then you can always select the non-navigation version and save money. Especially when purchasing a SYNC 3 related kit or replacement, many choose to use Google Maps, Waze or Apple Maps via Android Auto or Apple CarPlay to save money.
