I picked up my new A3 Cab' a week ago. It was supplied with an SD card for the Sat Nav, dated 2016. Like others, I feel most annoyed that it is already out of date. It does not have changes made to major roads around me last year. How can I trust it elsewhere?
I too use TomTom on my iPhone and yes, it is updated regularly. When I ordered the car (back end of last year) the SatNav was an extra. By the time the car arrived, it was included within the standard car. I am really annoyed that I can't trust it. My dealer tells me he has supplied the latest map and that he does not know when the next update is due, but that, when it does arrive, the usual cost is c.£150 for an update. For a car costing upwards of £36k, this is appalling.
