We bought a Garmin C-330 it's simple to operate. Around $450.00 Best Buy.
Just before a younger brother went on a trip to Chicago. (I didn't want to have to fly up there to help him find his way back...Baby Brothers :roll: )
He had never used one but took it with him, he said he couldn't get lost if he tried. He said they took it when they shopped, it told them where food was, gas everything.
My older brother uses it for rural estimates, a couple of supervisors took it up to Bolden's so they could find there way around. Another supervisor took it to Dallas to move his daughter to school.
Pretty awesome unit for the money,
We love it.
