I have a renault hire car at the moment with built in tomtom and have found it has a renault F1 car icon, does anybody know where i can get this or any other F1 car and if it is possible to install on my 825.
I seem to remember there being a generic racing car in the list of car icons already on my TomToms. Have you had a look there to see if there's anything suitable?
Pocket GPS World also has a load of free car icons, so it's well worth looking on their site too.
Another route would be the library of car icons on Home, but I think you need a TT which connects to Home in order to download the icons. I'm away from my PC at the moment, but IIRC the 825 is one that uses MyTomTom instead, so it might be an option for someone else to download it for you.
