Summary: I inherited one of these as a hand-me-down unit in 2009. It's old, but it still works. I did manage to make it react faster and work better by doing a software update (available at Cobra's weird little website), and so far it has been pretty reliable in getting me from point A to point B.
Summary: About four years ago I bought this model after a lady friend of mine got one and we made a trip with it. I subsequently also bought a Garmin because of favorable reviews but was disappointed because the Garmin was impossible to see in direct sunlight.
Summary: My Garmin 340C was stolen from my car and I took a chance on the Cobra. It works (sometimes) but software and graphics are far inferior to what I had gotten used to. On the plus side, some nice features like choice of a category and listing of all in that category in your area.
Summary: I tried to update the maps, and COBRA is charging $129! I could buy a newer unit and get current maps and more features. COBRA just stonewalled, and said this model was discontinued several years ago, and they would only update the maps for the $129.
Summary: My husband is a OTR driver and oftentimes is left with less than desirable directions to a drop off point. I got this for him, and he loves it. It has really made getting from point A to point B easy. His Cobra GPS took very little pre-study to get comfortable with and he's used it from day 1.
Summary: For the most part the GPS works just fine. It's late on telling you to turn sometimes. This Cobra has no idea if there is road construction, or any warning of them and no re-route instructions.
Summary: Cobra is pushing the "My Favorite Brands" functionality in this device whereby you can specify your favorite retailers and the device will attach special icons to those locations on the map as you drive. Over 600 brands are available to choose from.
