I have a Connie SE with an Android head unit fitted. Satnav seems dated and I’ve never been sure about updating it. From previous discussions it seemed like the consensus was maybe it’s easier to tether your phone to the head unit and use Google Maps rather than try to update the satnav. Seems reasonable. Could somebody please point me at some instructions as to how you tether your phone to the Android unit as I’ve lost the instructions I had and it’s not immediately apparent……
