I noted that when I connected this product to my vehicle and drove over 2000+ miles all over Europe all it would do was show voltage and well the vehicle location data, nothing else. I send it back to TOMTOM with as much info as I could and it came back saying OUT OF WARRANTY. Given I had purchased this from TOMTOM just a week-or-so before that's clearly not correct. The authorised repair paperwork waffled on about WHAT TO DO NEXT. However, this information was relevant to a navigation device. What I can see is that there is a change in the S/N so as the documentation states they have swapped it with another. We will see if this has solved the issue?
