hello everyone , when we first get we Prism Handspring Visor , we we be debate on if we should get the gp module or not . I be glad we do ! I have find the mapping software very detailed , and I can not wait for the Rand McNally Street Finder map software to come out . I hear that you can do point to point . I highly recommend the handygp concider the functionality and the price . there be so many different feature that you can do . I can not imagine why there have be people that have not enjoy this handy little device . I be able to name my house , my sister house , my favorite restaurant , etc. . . this be a totally cool toy on the cut edge . definetly a must have !
