I had some trouble with both starting the vehicle (22 XC60 Recharge) from the app and the disappearance of the maps (only shows current street name and home icon). The former returned to normal as quickly as it malfunctioned, but the map screen is largely blank. I read about holding down the windshield defroster button, then shutting off and locking
the vehicle, but no luck. Any suggestions, so as to avoid a trip to the dealer? Input much appreciated.
