The most significant problem I have had is with the combination power/traffic receiver cable. The mini-USB plug is right-angled, and does not stand up to repeated insertions. After 6 months of removing and inserting the plug (normal use, not abuse), the cable broke internally. As a result, it no longer powered the GPS. Replacements are more than $60, so I bought a non-Garmin USB power adaptor for around $15, and it works fine ever since. I now have a GPS without the traffic info, but I can live without it.
OK, the rest of my review:
I read some other reviews and, frankly, am very surprised. For one, I've navigated into and around St. Louis and the surrounding area, on I-55, I-255, I-70 and many other ordinary roads. My experience is entirely the opposite of that reported by another reviewer. I've never had any problems of that kind in the area.
Sure, I've identified places where the map does not correspond to the reality of the roads. That is not Garmin's fault but the mapping agency. On all but one case, the road was less than one year old and different than previously (Chattanooga/Nashville/Jackson TN, San Antonio TX, Kansas City KS). In one case, in "B.F.E.", the road had been blocked due to a minor landslide, but it was a "backwater" road that duplicated another major highway anyway.
In each case, the problem was not unreasonable and was simple to recover from. There's a standard report form for map errors anyway - which I took the opportunity to use each time.
I'm not a professional driver but, over a period of 18 months, I used the GPS to travel extensively and covered around 48,000 miles using it to navigate. During that time I never relied upon a map to supplement navigation (although I had one with me).
Any GPS is difficult to reprogram when actually driving, so I don't recommend it. It's far more safe to pull over and take a few minutes break anyway.
If, like me, you are prone to taking minor detours to take in a change of plans at short notice, you might find the voice a minor annoyance, continually reminding you to make a U-turn as soon as possible, etc., so you could be selective about the times you use the spoken announcements. Or you could download the free software and reprogram the voice.
Any GPS is only a navigational aid, never a substitute for the eyes and driving ability of the driver.
I do not rely entirely upon it to navigate my trip, but chiefly on what I see about me as I make my way, because I know that no GPS will tell me about the temporary roadworks just around the corner, or the broken down truck 200 yards in front.
I love the size of the screen. The level of detail can be selected, but is good. It's easy to save favorites and to choose destinations. It will quickly find alternate routes if you have to detour.
If you are traveling to a large number of different places, and likely to create many favorites, I recommend you hook the GPS up to your computer and use the free MapSource software to manage the trips and favorites while you are at home or in a motel, etc. The GPS is only as good as the maps, so take the opportunity to report any outdated mapping issues that you might find.
I can't repeat enough that it's not a co-pilot, but a navigational aid, with emphasis on the aid. Still rely on common sense and your own observations.
Driving is back to being fun and this GPS has helped. I wish I had one of these thirty years ago.
If I lost this GPS I would buy another Garmin, but one of the new ones with 3-d topographical maps and lifetime map updates. That's the most significant change from this model.
