How to start/extend TomTom Traffic on a Mercedes Audio 20 SD card Garmin Satnav?
One was on older s/w
the other bang up to date V11 S/w V11 2018 maps for Europe.
Brand new cards when I got them which needed to be linked to the car.
Both tell me "No valid subscription"...but my B class has never had it and the card -paired to the car never runs it...and Mercedes dont have a clue on how to extend it?
Its bonkers... they supply the cards but have no idea how to extend the life of the live traffic...(or start it up)
Have I got duff cards? Fake ones (which all work with the car perfectly)????
Can Tomtom help me...(and actually end up helping a lot of other people on the Merc forums who are going as spare as me!)
