I just upgraded my radio to the entune navigation and was able to get entune working with my phone but the map is off causing weather and gas prices to be off. When I check the gps location and coordinates the coordinates are correct (matched compass on iPhone) but the map shows it in the wrong state. Any ideas? I did upgrade it manually from 1.7.4 to 5 with usb key. But problem was there before and after. Any suggestions? Also is that the latest firmware?
