My GPS is a dash mount unit that talks. I don't know how I ever got along without one. I drove a truck for many years and was pretty good with using a map and my instincts, but this thing is wonderful on trips. Tells you about anything you need to know when traveling. Looking for a Hardee's or Burger King? It will locate the nearest one for you. Tells you how far to the next turn, what lane to get in ahead of time, how fast you're going, etc.
I bought a handheld one a few years ago for fishing, but sold it when we moved because I thought I would be mostly river fishing up here and could remember my spots.
