My satnav system was built in to my car and I am unable to access its serial number . I believe I need this number to download. What can I do?
You can find these numbers on the physical SD card, e.g. 86721-00362.

Have done as instructed but have not been asked by TomTom for credit card details so I have not paid them. What have I done wrong? I assume thus that I have not yet been connected.
