After a recent re-configuration I lost the GPS symbol on the app, and it no longer shows my speed. App and hardware were, and still are the latest configuration. It disappeared immediately upon boot up of the new configuration. I checked the GPS itself, and it is still sitting where it was when it was working properly. Net Radar is working properly too. I did a second re-configuration to make sure I hadn't accidentally used an old one, and still no joy. Anyone got any ideas?
