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.

Customer Reviews

Nice Looking With Great Screen Resolution, but.....
My wife bought me a Cobra 4500 for Christmas. It's a very attractive vehicle GPS with a big screen, crisp resolution and looks/feels sturdy. However, I have some complaints about the software design that I'd like to share. First, the routing software makes some directional mistakes when on freeways. For instance at freeway interchanges, sometimes it will tell me to get onto the upcoming freeway in the wrong direction (i.e. "keep to the left onto I-10 West" when it should say "keep to the left onto I-10 East"). It will always correct itself at the last second, but the correction usually ends up being just before the ramp. In an unfamiliar city, that would not give me time to make a safe lane change. Also, the 3-D graphics are so poor that I've had to select the traditional map view to navigate. As for traffic, it's hit and miss. Sometimes I get the traffic icon on the map as soon as the radio announces the accident, but sometimes I get it 20 or more minutes later, or not at all! Also, for some unknown reason the software developers decided to program the unit so that the user is unable to get a traffic warning notification pop-up unless a speed reduction was posted with the accident. I've encountered several major accidents where traffic has been at a near standstill, yet the pop-up that allows you to select auto re-route did not come up on the screen (probably because speed reductions are not being posted by the traffic provider, Clear Channel Radio). If the pop-up doesn't activate (which it has yet to do for me), you're forced to use the normal detour function to get around the accident. This process is very cumbersome because you have to zoom in on the icon, look at where the accident is located, and then get to the detour screen so you can select your detour -- not something you want to do in heavy traffic! Hey Cobra, why not let the user decide if he/she wants to be notified of all accidents instead of the unit deciding for us??? I've notified Cobra of all of this and I'm hoping they will come out with a software update to correct these problems. Until then, I'm only lukewarm about the unit.

Excellent, but pricey.
The receiver has a large touchscreen and is by far the easiest to operate and see while driving. I justified the price tag because I do need this for finding customers - I commute 60 miles one-way to work daily and don't know the city well. I go mobile to see five clients per week on average. I used to use MapQuest to print-out driving directions, but I don't feel safe navigating from a paper print-out while driving.
Upon browsing GPS at Fry's Electronics, this unit stood out among the rest as being superior. I figured out the operation of the unit within minutes.
If you select an option and do nothing, a pleasant female voice instructs you at to the options and purpose of the current screen. I have yet to read the instruction booklet. And the maps preloaded into its hard-drive are quite accurate - indicating obscure back-roads.
The suction-cup mount has broken loose several times, which is not what you want to happen to a unit this expensive! I have decided to purchase an additional mount for my vacation vehicle and permanantly affix them to the dashes of both vehicles.
Yes, I spent $1000 on a GPS reciever - but my other alternative was to spend $3700 on in-dash radio/GPS/DVD recievers for both vehicles. The only reason I spent this kind of money is because is really is for business purposes and I need the tax deduction!
Overall - I recommend this unit to anyone willing/stupid/needfull enough to spend this kind of money on what I consider to be the best unit on the market.

Promising, but flawed
We were in need of a navigation unit to guide us through our July 4th road trip. The route was Houston, to Corpus Christi, to San Antonio, Austin, and back to Houston. The 2000 Acura TL that we have has navigation but it's too small for a family trip. So we took the van and the Cobra Nav One with us. At first, it was love at first sight. The unit is gorgeous!! The bright touchscreen was big, bigger than any other competitors unit. And bright, oh boy, even during midday in Texas sun at the beach, being mounted on the dash, the unit was easily readable and legible. Best I have seen yet. The map data it has was incredible. Even the tiniest nooks and cranes in the backroad is contained here. Even the slightest curves on the road is acknowleged. The bazillions of interest points it has came in real handy when you're in a strange town looking for a particular restaurant.

Those are the good points

The downside comes, when you actually use the main feature of the unit, navigation and routing. The software is one of the dumbest I have used. It's routing capability is not nearly as flexible nor as dynamic as the navigation system that comes stock with the 2000 Acura TL. Once the route is set, the Nav One unit will STICK to it. If you change direction, it will keep nagging you to turn around, 70 miles turn around, to return to the original route, instead of making a new one. The only way to fix that, is to go back to Main menu, and choose the destination again. Only then it will reroute with the new direction. The Acura TL navigation does all that automatically. Much smarter than the Nav One... The routing itself is majorly flawed as well. We did not get lost in Corpus Christi, as it is a small city with simple laid out. That changed quickly as we got to San Antonio. The unit got us lost multiple of times. At one point, it tried to get us to drive into a 1-way street, the opposite direction... At another, we drove under a bridge and the Nav One lost signal and shuts itself off instead of staying on to reconnect o_0. Don't get me wrong, I love the Cobra Nav One. It is gorgeous and flashy, target for thieves no doubt. However, all the bells and whistles become meaningless if the navigation and routing do not work properly. The unit is going to be returned. Until next time, Cobra...

Pros:
1) BIG bright screen, one of the best in the market. Easy to read in daylight.
2) Jam packed interest points
3) It's sexy and gets you the ladies
4) Very very detailed mapping.

Cons:
1) Routing and rerouting are broken
2) The software is not very smart.
3) Signal loss = automatic shut down
4) Did I mention the routing and rerouting are broken?
