The primary reason for WiFi on a non-navi unit is to allow the radio firmware to self-update. If you connect the car to your home gateway, the radio (AV Unit) will download and install firmware updates automatically when available while the car is parked. That can be important when new applications arise that existing firmware may not possess or may not handle properly, such as when Apple routinely "moves the furniture" in their IOS. On navi units it will also allow routine updating of maps without buying a CD or SD card.Thanks for your reply. My vehicle is the base and does not have NissanConnect access and does not have Navigation built-in which is why there is no SD card slot so I was wondering why wouldn't it just be disabled as I see no other benefit.
