Amazon.com Product Description
Enjoy traffic relief while commuting to work or taking a road trip with the Cobra Nav One 4500, the first fully integrated portable navigation system with real-time traffic updates. The plug-and-play GPS navigator features a matchbook-sized traffic receiver that offers up-to-the-minute information on traffic accidents, congested roads, and construction zones in 48 major metropolitan areas across the U.S. As the unit receives the traffic data--which transmits via an FM radio feed from Tele Atlas N.V. and Clear Channel's Total Traffic Network--it processes the information and automatically suggests alternate routes, letting the driver detour around the worst snarls and enjoy a stress-free commute. It's the perfect unit for frustrated commuters and other folks who spend much of their day in the car. The Nav One 4500 offers more than just traffic updates, however. It also comes preloaded with searchable North American street-level detail maps and more than 7.6 million points of interest--more than any other portable device. The points of interest are organized into nine general categories, including amusement, automotive, medical, and travel, and then further sorted into approximately 200 subcategories. Drivers can also customize the route preferences to make traveling easier. Don't want to deal with stoplight-heavy streets or particularly curvy roadways? Simply program the Nav One 4500 to meet your criteria and it'll find the best route for your needs. Once you've chosen the destination, the Nav One 4500 provides turn-by-turn directions and voice guidance on its 5-inch color touch-screen display. The screen produces up to twice the brightness of other units in daylight mode, making it easy to read even in the mid-day sun. It also offers 3-D views for easier navigation, along with 14 levels of map zoom and exclusive terrain display, making it simple for the directionally challenged to find their way. Additional features include an address book that holds up to 1,000 addresses in 20 customizable folders; multi-stop routing for drivers with complex itineraries; proprietary iASAP technology that provides for faster satellite acquisition and uninterrupted navigation in urban canyons and dense foliage; and a traffic antenna that attaches easily to the Nav One 4500 mount and moves with the unit from vehicle to vehicle. The Nav One 4500, which mounts conveniently on your dash, comes with a free three-month subscription for the traffic service, which afterward costs $59.95 per year. What's in the Box

It is fun to use, has great versitility, and is easy to program. I can't ask for much more.
 A product with a lot of flaws August 24, 2007
This is my first GPS system so I did a lot of research online before I went ahead purchase it in March 2007. I wanted a large screen one and traffic system. 4500 seems to be the perfect match.
Pro: large screen, real-time traffic system saved me many times, and reasonable routing suggestions. I don't have the rerouting adaptation problem as the other reviewers and if I get into a side road, it'll recalculate immediately. Maybe they fixed it in the most current software batch. Their customer service is superb.
Cons: I had this unit for 5 months and have to return it now. As many reviewers said, this unit has slower routing calculation and I didn't realize it would be a problem until I was driving on a highway waiting for the exit.
Even though I have the most current database batch, I would see some not-so-new highways disappeared suddenly during the drive. It would come back eventually but it doesn't feel good to see yourself driving on a blank space for several miles, especially if you travel to a unknown place at night.
Road side of a destination seems to be wrong 80% of the time. We all know after 1 month of usage to ignore the final destination instruction.
After 2 months, the address book, all travel location information, and user settings were wiped out automatically and I have to reset everything. After it happened so many times, I called Cobra and they gave me another software patch. It seemed to fix the problem.
When used in big cities with a lot of traffics, its routing instruction can be so wrong. It usually gives me the worst routing suggestion, i.e. chose the busiest road, or a longer route, or use local highways with a lot of construction going on instead of an interstate highways that are much less congested, etc. This unit's routing logic seems to work better with mid-size to small-size towns.
The mounting is cumbersome. After taking it off and putting it back on whenever I have to park somewhere, the V12 cord connected to the car broke. I had to call the customer service and they sent me another cord immediately. Did I mention that their customer service is very good?
The final flaw which makes me wanted to return it is, one day the beautiful female voice was gone. Never come back again.
I feel sorry to have to put a bad review on a product. I hope it would help others to avoid the frustrations I have gone through.

I got the unit for Christmas, attracted to the good display, but leery of the reliability, both due to other's reviews. I have no serious references to other GPS units, aside from one in an ACRUA MDX that was built into the console, and was very impressive. My 4500 is away to be repaired now, they say for about 3 weeks, with very little use when it worked. I was careful with it as was possible and used it only on major highway trips.
I don't understand how, say an Acura, can have GPS that can sit out in cold and extreme heat, and survives daily driving, and the 4500 Nav One breaks while being treated like delicate china. I also bought every accessory that SHOULD have come with it for the price.
I hate to give bad reviews, but I have to say, if you need a GPS you can count on, this model is high risk. I would want to know this if I was considering buying it. The software can be a little bugged. I got stuck in some loop (it refused to lock in one zoom level) while on the road and eventually had to shut it down and reset to defaults. No idea why. It's sometimes not very precise and a little sluggish in real time rerouting, which can be frequent, as the unit gets lost for no apparent reason while cruising down an Interstate.
It does look nice, and has many great features when it works. That said, I had higher hopes for a portable GPS that really isn't portable, unless you have a portable power source. It was missed on my last road trip when it quit working, and will be missed while in the shop. For me the unit is more a toy than a tool fortunately, because as a needed tool, I would not highly recommend it.
update: Only took about ten days and got a new replacement for the crashed one. The new Nav ONE seems to perform better than the defective one did, meaning it doesn't get "lost" and recalculate for no clear reason, as before.

The unit is very large and bulky. It does have a very large viewable map which is nice. The unit I had worked about 1 week then would not power up. I am completely dissapointed with this brand and unit and am trying another one.

I am very pleased with this GPS unit. I was alittle worried after reading some of the reviews, but am very happy that I still ordered it.
The graphics are by far one of the best. It has very detailed graphics, unlike many of the other brands that have a more cartoon look to them. The graphics are compariable to what you would find in a in-dash unit. It is very user friendly, and easy to navigate. The unit does weigh a bit, but have not had any problems with the suction cup as I read about. As long as the window is clean it works great. I have even drove over some really bumpy roads and the unit has not come loose.
For the money and what you get this is a terrific unit, and would highly recommend it.
