GPS not work with Subaru USB port
When either an iPhone 5s or a iPhone 6 is connected to the USB port in a Subaru (2015 Outback), the GPS shows a location of 0 Deg Latitude and 0 Deg Longitude (i.e. in the Atlantic Ocean off the coast of Africa). We now are having to use a charger in the power port ('cigarette' lighter) to keep the phone charged. I believe the issue is when the phone is connected via a sync cord to the Subaru computer system via the USB port, it shuts down the GPS module in the iPhone.
Any suggestions on how to use this USB port and still have the GPS in the iPhone work??
iPhone 5s, iOS 8.4
