Updating Tom Tom One

Hi Folks

I bought a Tom Tom One about 3 years ago. Is it necessary to 'update' it every now and again, because of route changes (new roads being built every now & again) etc?

If so, how do I go about updating my Tom Tom? The cd that was provided with it does not seem to work properly.

Thanks in advance for your response.

This will update your software and you can choose if you want to order new maps. You should also get access to map share as well depending on your tomtom unit.
