Recently I've read about an iGo version being available for Windows XP / Vista. However, there is nothing mentioned about a PC version at the Nav N Go website. I contacted the company to find out if in fact they have a version for Laptop PC, TabletPC and UMPC users. Unfortunately, their reply is that they do not have a PC version, and they do not intend to make a PC version.
iGo is an excellent GPS navigation software program, but it only is available for PocketPCs and PNDs.
