Via 135 constantly drum rolling
I bought a via 135 last year (brand new) as a gift for when my son could drive. Yesterday I unwrapped it and tried starting it up, it came up with a message that I needed to update it and plug into a computer and then went to the TomTom screen and a drum roll, after a few seconds the TomTom logo disappeared and then reappeared and then I got the drum roll again. It just keeps doing that. I've tried plugging it into the computer and switching on but it seems to be stuck in a loop of the logo appearing, a drum roll, the logo disappearing and then it starting all over again.
I've tried leaving the device on charge and having another go but it's made no difference. I've tried holding down the on off button but that hasn't made any difference and I don't know what else to try now.
This was supposed to be a great little present for passing his test and it's not really hit the mark at all so far.
Please help if you can.
