Hello! my S40 recently received the Navi. This was shown by the monitor no longer driving up. After I was at mine it turned out that one of the components is opposed (TMC, GPS antenna, control unit). So exactly it could not narrow down my workshop. It would now be about 3-4 working hours only to find the error. That alone would cost 200.-. But there is nothing repaired then. After I only have my car for 6 months, I immediately got in touch with the car house where I bought the car. They are now the opinion that on the Navi is not a guarantee and therefore I have to pay the defect itself. Can someone confirm that on multimedia components the used car warranty does not apply to me? Thank you!
