Car hire with TomTom?

Hello, there. I was in London last month. I hired a car there in order to have an easier access to some destinations. I also paid for TomTom ONE Europe as I believe it is called. It is something like GPS system. Sorry for my uncertainty, but I am not much familiar with hi-tech. But, this system was great. Navigations instruction is made in almost all European languages. It was easy to use, even for me. So I think you wont have a problem. In this way you will know exactly where your currently position is.

Howdy, people. I am going to UK next week. Since I would like to explore it on my own, I was thinking of hiring a car. My friend recommended me to hire a car with TomTom. Do you have any experience in that field? It would be great if you could give me some info. Bye!
