I think it will depend on whether your operating system is up to date - sounds as though it should be. If you connect your sat nav to your pc having installed 'Tom Tom Home' (free from the tom tom website), it will detect whether your device needs any updates.
The tech support at Tom Tom isn't bad - try posting a question there if no one else has an answer here.
As for installing the map, the map will need to be written to an SD card, unless the 910 has a hard disc (sorry if it does, I don't know much about the 910)
Do your maps that you have already read from a built in hard disc? If they do, it will then depend on the free space. You may have to back up your current maps, (again via Tom Tom Home), then delete what you don't need, and then install the purchased map. This process is valid for SD cards or indeed if a hard disc exists on your device.
