My wife and I have GPS built in one car and love it. Rented a GPS to go with a rental car recently on a trip to Florida and found the portable one great. Now, we want to buy a portable unit to use with other vehicles, but would also like to use it for marine navigation. Anyone aware of a unit that can be used for streets in the car and on the bike as well as run with marine charts for our sailboat? I noted that Garmin and Magellan both have marine units that can do that, but they are rather large and neither appears as user friendly with pre-loaded street data as the newer car navigation units.
Any ideas, or do you think we just have to wait a bit longer?
