off road and as a back up nav. program. I down loaded a map for the Anza Borrego Desert that is exactly what I wanted. My only problem is that the GPS function on my Lenovo A7000-f won't work. Does anyone know how to turn it on or what could be wrong? I've tried several different ways with no success. Well, I'm off to put a coat of varnish on some teak and then change the U-joints on my jeep. Looks like a full day ahead. We're getting ready for a weeks cruise to New Port Beach as well.
