I have been considering buying a handheld GPS for the last couple months and have been looking at several models. Yesterday, I spotted a new app for the iPhone. It's called GPSNavX and is by a company that has several other nav programs for Macs. It can do many of the same things a regular GPS unit can do and gives you access to free charts for your area or the world. It's not cheap at $50 but beats paying $500 for a Garmin. I will be downloading it and checking it out when we travel to the delta and a mapping GPS unit is the only way to go! Check the site here.
