Took my Droid with a ram mount to ocean city MD. 1104.9 mile ride, not once did i get lost. I rigged up a charger too. Google maps rocks. Love my ram mount. make sure it fits snug and haveba case on too
check out mapdroyd. lets ya pre download maps for your state in case ya cant get cell signal for google maps/navigate. its vector based rather than tiles so its also pretty tiny. leaving more room for mp3s and photos.
seems to work for me better than map area in google maps.
on the iphone i havent found a better map app than motionX gps. its tile based so maps tend to get big. but has topo and noaa maps.
wish i could find something as nice for android.
Those are neat, but i Gota hand it to thevram mount, its sturdy as hell, that tank one looks kinda cheap. Also, Google maps allows caching and downloading map areas, which works pretty good if you know what your doing. I also use giaa maps. Nice app
