Thank you for your quick response P33dro, and also for your help.
One more question: I downloaded the map you just told me, It said something about a meta and a code, what should I do with it?
Also, I unzipped the file and got a United_States_2GB_870_3406 folder, where should I put that in my Tomtom? Does it have to be the files that are inside that folder, or the whole folder direct to my tomtom?


I really appreciate all your help, and sorry I'm 100% newbie with this stuffs.
