follow up from above. Google Map works great with Phone receiving NMEA from ublox GNSS over bluetooth (+ GPS Connector app) and gpsd running concurrently. WAZE is a bit picky and it doesn't like gpsd. so, the best setup is without gpsd service and turn off location permission for your Android Auto app. this will just rely on phone NMEA only and without any aggregation. Both Google Map and Waze work seamlessly with high accuracy. there is an extra step needed to ensure GPS Connector app is communicating with the ublox over bluetooth where at times both doesn't click. anyway, I think this is the best setup for me.
