Hi. I got a TomTom 920 yesterday and updated the map 850.2781 and Navcore 8.562. The problem is it shows TomTom 530 when it starting. And now it also shows TomTom Go 530 when I check the version. I see the case has "GO920(4M00.900)" but I am not sure it is a 530 or a 920. Any ideas to fix this issue? Thanks.
