Summary: Pros: Works most of the time. Will get you there.
Cons: No internal battery, must be plugged in to be used. Slow. Unit shuts off for no reason. Some routes are definitely the long way around. Did I mention slow?
I've owned the Cobra NavOne 2500 for over a year now. It is the first GPS system that I ever used. The unit is fairly easy to use, the menus are relatively intuitive with some quirks.
Summary: If you travel the roads across the USA, please do not buy this unit. I am a professional truck driver, and I have had nothing but headache after headache using it. The GPS is too slow, so you are actually past an off ramp or exit when it shows up on the screen. It will take you off a major Interstate, drive through small town streets with stop lights, and then put you back on the exact Interstate it just took you off of.
Summary: I have had the cobra naveone 2500 for about 4 months now. I was looking for a lower end unit with a lot of points of interest and one that covers Canada and the US. Mine came with an ac adapter, 12 volt cord & windshield mount. Others have an internal battery power source that would have been a nice feature.
As with many reviewers on other gps units this has similar flaws.
Summary: It's Simple To use and the voice is clear as a bell. It lets you know if you're turning left or right ahead of time so you're prepared and when you get to the exact spot for the turn it beeps. And... If it's so hard to remember what direction was told to you a minute ago, there's a directional arrow at the bottom left which points in the turn of your direction. If you miss your turn the system reconfigures to where you are and will direct you from there.
Summary: I decided to try the 2500 after trying the 4500 and returning it (Why? I have no idea!) The unit is a small, but the interface is really bad. The 3D graphics are POOR! The unit does not tell you to turn when you are supposed to, at the actual turn, instead it beeps. If you are approaching a turn, it will tell you announce the following:
"In 0.2 miles, turn left"
When you get to the actual turn the unit just beeps, with no turn direction, so if you don't remember if you...
