Fatboydel Posted July 12, 2023 Share Posted July 12, 2023 Hi Guys, I am having issues with the SatNav on my 2014 2.0tdi with MMI Navigation Plus. While driving along, when you set a route, the satnav wanders off course, across fields and all over the place, telling me to turn around all the time. Basically it is useless as it is. It is like it loses the satellite signal? In the old tomtom days we used to have to load a satellite update file, as the satellites move, is there something like that I can load?

Steve Q Posted July 13, 2023 Share Posted July 13, 2023 I'd recommend a diagnostic check to see if any fault codes flag up. But a suspect the antenna has failed. Quote Link to comment Share on other sites More sharing options...
Fatboydel Posted July 13, 2023 Author Share Posted July 13, 2023 I had a diagnostic check and there was no code relating to this. Is fixing the antenna an easy job? Quote Link to comment Share on other sites More sharing options...
Fatboydel Posted July 13, 2023 Author Share Posted July 13, 2023 So does the roof antenna control the satnav, I thought it was just radio and phone? Quote Link to comment Share on other sites More sharing options...
