Interesting. Have emailed two of the suppliers on Ebay asking the same questions and whether or not the card can receive live travel updates, after being stuck on the M6 for three hours, on the way back from picking it up!Neither have so far replied.
The good news was that the car behaved well in nose to tail traffic for three hours, no issues, and then purred off when we finally got past a bad accident and recorded 39 mpg on the readout for the 150 mile trip.
