No Calls, Please: Keeping your same old cell phone for awhile? May as well get a powerful handheld touchscreen GPS chart plotter, such as the Garmin Oregon 400c ($600). The bright, 3-inch touchscreen lets you have access to the sensitive GPS receiver and preloaded BlueChart g2 cartography, all in a rugged little package that runs on two AA batteries.
