Hello all, after upgrading the nav for 1 month only, it now doesnt work. It just says initialising on the screen. If I did a factory reset would it restart the app? Audi have told me that I have got to pay £209 to have a diagnostic which I don't think is fair cause it worked perfectly before, this has only happened since paying £14 for the 1 month upgrade through the Audi store. Thanks for any advice given.
