Mazda Miata TomTom navigation not working
I have a Mazda Miata 2011 with a built in Tom Tom navigation system (NVA-SD8110).
I tried to update the system and now the system won't start up properly.
When power up the Mazda logo appears (as it should) after a few seconds the screen turns yellow and a symbol appears in the middle of the screen, looking like a chip with the text "WISMO 218". After a few seconds a red cross appears over the "chip" and the unit boots up again and the sequence repeats.
What to do? Thankful for support!
