I've used Garmin Streetpilots in the past, and it served me very well. They are SO incredible useful. In fact I would be still using that old boxy one I originally bought in 2004 today had the tip of the plug not come unscrewed resulting in a short that blew the fuse for all the lights in my dash (kinda scary as the sun set I wasn't sure if I'd be able to see my speedometer!!) thank goodness for ubiquitous autozones. At any rate, I actually bought the Garmin nuvi 40 over the 1300. I think I should have gone with the 1300 because the 40 has proved temperamental and "iffy" in certain locations. but barring another freak accident I'll never be able to prove it. I went for cheaper (40) but maybe thats not always better. :( I do hate that they have SO MANY models. I mean really. is this necessary? Customers want SIMPLE. Telling the difference between some of these seems impossible. That aside, with regard to this model, which I think I wish I had, PLEASE BUY THE LIFETIME MAPS! That would be indicated by the 1300 LM (or whatever number model you buy). I made the mistake of not getting LM, thinking "hey these devices don't last forever." Oh, but they do last a while. And maps are expensive. sadly. making this the better deal in the long run. Processing Speed Garmins do a fine job processing. I've never had a trouble with any of mine, and at most they take a minute or more. The longest is in certain rural areas, or when switching locations from state to state (as in, you turn it off in Nevada and turn it on again in Arizona.... It takes the satellite a while to calculate.) Map Quality & Accuracy I HAVE had maps trouble but I actually blame the confusing road systems more than I do Garmins. Most areas do fine. Ease of Use These things are ALWAYS easy to use. Great displays. Intuitive menus. I'd have no problem handing this to anyone- youth, adult, and older adult.
