I am new to GPS systems and have just gotten a tomtom go510. I was hoping to find a POI with state, federal, and national campgrounds. The one that comes with it is pretty weak. I found one but it is csv format and I want to convert it using the online tool. However, it gives me an error message and says it didn't convert (the file is on my hard drive). What does it mean when it asks for the bmp file on the second line? I never put that in when I try to convert and maybe thats my problem. Thanks.
PS: If it does work, how do I get it in my GPS device?
