Your vehicle has an available satelite navigation option in the infotainment system for a few hundred dollars. It is proposed here on Bien Sur that the same 'always on' navigation system is quite marketable if made available on your mobile phone as a $20.00 app and will be functional whether or not you have a mobile signal. You could download the phone maker's app for $10.00 or the Garmin(TM) for $20.00 which will have updated maps with a life time guarantee as proposed by Warren A. Lyon. Bueno! Sze Sze!
