Amazon.com Product Description
Cobra's GPSM Nav One 2500 is a specialized, portable navigation system designed for use in vehicles. Simply pick a destination via the easy-to-use touchscreen and you're on your way, as the Nav One 2500 automatically calculates the best route and gives you turn-by-turn directions (with voice and visual guidance) to your address or point of interest. The complete plug-and-go system also includes a cigarette lighter power cord and windshield suction-cup mounting bracket, letting you use it in any vehicle without performing an elaborate installation routine. The Nav One 2500 features Cobra's iA.S.A.P. (Intelligent Accelerated Satellite Acquisition Protocol) technology, which takes advantage of 12 parallel channels for faster acquisition and uninterrupted satellite signal reception in urban canyons and dense foliage. And in places like tunnels and underpasses where satellite signals are traditionally lost, this handy GPS unit's nonmagnetic gyroscopic turn-rate sensor provides directional information to keep you on the map. Meanwhile, the easy-to-read 3.5-inch color display features an ultrabright backlit touchscreen and a photo sensor that automatically adjusts the display for day or night viewing. The features combine to offer superb readability even under bright, sunlit conditions and easy access to specific functions in any given mode. A perfect traveling companion during your drive, the Nav One 2500 comes with a preloaded North America street-level detail map that covers the 48 contiguous U.S. states, plus Hawaii and the major metropolitan areas of Canada. The maps come already unlocked and ready to use, so you don't have to download anything from CDs or your PC. Also accompanying you on the ride are more than two million points of interest, which are searchable by business phone numbers; trip data functions such as an odometer, speedometer, and trip timer; and a trip planner that lets you preprogram up to 10 destinations per plan, for a total of five total plans. The unit even includes a trail mode so you can go off-roading and mark your favorite waypoints for future return. For your convenience, this GPSM system includes English, Spanish, and French navigational voice languages and an automatic shutoff system that preserves battery power. The unit is backed by a one-year warranty on parts and labor What's in the Box

 Poor Product December 14, 2006

I had high hopes when I bought this GPS system.
When the Cobra arrived, I eagerly opened it and read the manual. The manual takes about three minutes to read because there isn't much in it. The learning is hands-on with the machine.
But, YOU MUST BE IN THE CAR WITH THE UNIT PLUGGED IN TO THE CIGARETTE LIGHTER BEFORE YOU CAN TURN IT ON!
That's right, folks. No adapter for in home use. You can't sit in your favorite chair, snap the unit on and learn. And the unit doesn't have any batteries so you can charge it up in the car and then take it with you when you step outside.
While learning, I added three address to the Cobra and suddenly the unit was out of memory!
Overall, a poorly designed product.
I returned it. Won't buy a Cobra in future because of this one experience.
 I like it January 7, 2007

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. Again, I like it.

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 had to turn right or left when the unit announced it 1/4 mile back, tough luck. Look at the screen. The screen rendering is also bad. The unit I tested, when the route was claculated and displayed, all streets not on the route (side streets) were not displayed. Even though these units tell you to turn left right etc., sometimes two streets are close together and you need to glance at the display to see if you are turning on the first or second street. So if the side streets are not displayed, you have to guess which is your turn. Also, many times the unit will tell you that your destination is left, when it is on the right and vice versa. The maps are horribly outdated with many streets no longer in existance still being directed to. Also, a lot of streets already in existance for years are not on the system. Spend an extra $100.00 and get a Garmin Nuvi with text to speech turn directions and a whole lot of other stuff. Stay away from Cobra products. They make great radar detectors, but make horrible GPS units.
Works ok, but has similar problems common to others February 12, 2007

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. In an area you are familiar with it seems to take you on round about routes at times to reach your destination. When you are in an area unfamiliar it will get you there.
I mainly bought the Cobra because I heard it locked on to satellite fixes faster then some other brands. It will do this within 30 seconds most times.
When driving through a tunnel it re-acquires the sattelite position in about 5 seconds when you have a view of the sky again. A couple of strange anomolies I have found occur everytime at the same locations. When driving on a Vancouver expressway in 2 areas the voice command tells me to exit but you can clearly see on the map its routing you off the exit, across the intersecting road and back onto the same expressway again. One intersection,the voice promt will always tell me, right turn ahead but the map and arrow indicate a left turn.
Id say if you follow the map its 99% accurate, the voice command maybe 90% accurate so always refer to the map or turn by turn list.
I updated the unit with Cobra the first week I had it. There were 3 updates issued in the time mine was manufactured and sitting on the shilf in the box.
A Walmart store and the road into it that were built just over a year ago do not show up yet on the map.
Another reason I chose this Cobra over the Magellan was that there customer service was good. Originally intending to get a magellan but once I started reading reviews , quickly heard nothing but horror stories about there customer service with Magellan.
All in all the Cobra works well enough for me. It offers more points of interest stored in memory then most others in the price range and does aquire sattelites very quickly as I was told.
I have read a lot of reviews from Magellan, Garmin, Tom Tom and other gps units and all have very similar complaints regarding routing and anomolies as metioned on my local expressway.
I think gps units have a long way to go yet till they are 100%efficient.
GPS units are not as good as I had expected but are still too valuable a tool to be without.
I will be travelling across the US a couple times this year and will really be able to put the Cobra to the test.

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. When it recalculates, it will freeze the screen, you cannot turn it off or change the touch screen, your only option is to unplug it. You have to watch the screen carefully, the voice command will tell you "bear right", when actually you go to the left, or it will tell you to turn when you make no turn at all.
I could go on and on, I have updated it, returned it for a new unit, still the same problems, I paid way too much for it at a truck stop and they will not refund my money, so please do not buy this junk from Cobra.
I only gave it 1 star because the software made me, if I could have I would have given it a -5.
