Yesterday m Navigon 7210 could not find any satellites. Despite several reboots it i not remedy the problem. I eventually resorted to a factory reset and it fixed the issue. The sat nav seems to be responding in a more efficient manner since.
It reminded me that every 2 years or so you need to reformat a PC and install the sw so as to fix any OS issues and streamline its behaviour. The same can be said for Sat Navs. I would recommend an annual factory reset as it will clean out any “gremlins” that might be lurking in the sat nav’s operating system.
