My Ipad does not have 3G so many of the functions that require GPS type connectivity don't work. With a PC, you can buy small GPS units that plug into the USB port. You can then, for example, use maps on your computer with your GPS to find out where you are and where you're going. My question is whether there's something like that which can be used on the Ipad? Any ideas? Thanks for taking the time to help me.
