Hi to all.
I just got an tomtom rider 450, used as a gift, but when i try to connect it to "MyDrive" on pc, it show me like i have a rider 400/410.
In my nav, in menu, info, shows me rider 450.
Some one know why this happen? thanks a lot. Apologise for my bad english.

it can be because of the serial number starting with the same initials. you can ignore that as long as the updates and services work for you
