You're in trouble now!!!
Tell you the truth, I am a little weak with techno gadgets. I work on computers and servers, but when it comes to things like cell phones, I can barely make a call.
Navigation is easy for me, the military drilled that into my head, without a GPS. For road trips, the GPS is really handy.
I was able, as was my girl friend, to use the GPS with minimal instruction. The software is really easy. Little icons with labels like FOOD, push enter and a list comes up, pick one and it will tell you how to get there from your present location.
Or, the other option is one that just provides Lat/Long or UTM location. If you ever have to call someone for help, it is handy to tell them where you are actually located.
I know lots of girls that have GPS and use it effectively. The newer models are super easy to learn and use. Cheers!
