I have a 2017 Volt. My Samsung S7 just updated the OS to “Oreo”. Ever since, I have been unable to use the nav apps through Android Auto. It lets me set up the trip, but after I start driving, a dialog bubble pops up on the map stating “Lost GPS” or “Searching for GPS” and it stops giving directions. I’ve had both Verizon and the Chevy dealer troubleshoot this without success. Has anybody else seen this problem? Any suggestions?
