I've got a bit of an issue with the Sat Nav. It's hardly crucial but it's a bit annoying. The location keeps resetting to London, and it takes about 45 minutes to an hour for the system to pick up the location. Once it's on, it's perfect - but then the system loses the location when you switch off. I'm running the latest disk that OB sent me, and stupidly I threw out the old one so I can't test but the problem only started a few weeks after I swapped disks.
Has anyone else had something like this before?
