Cobra NAV ONE 4500


Talk about seeing the big picture. Cobra Electronics' NavOne 4500 portable GPS navigation system ($929.95 direct) sports a 5-inch, 320by-240 pixel touch screen that makes it a lot easier to see your desired route at a glance. The device includes a...

Large 5-inch screen. Excellent Points-of-Interest database. Integrated live traffic data

Limited routing options. Routes generated seemed less optimal than routes to same destinations generated by competing products

The NavOne 4500's 5-inch screen and integrated live traffic data set it apart from other GPS devices, but its lack of routing options and indirect route suggestions are disappointing.

Cobra NavOne 4500


Five oversized function buttons located to the right of the display are used to power up the unit, enter the main-menu page, adjust volume settings, activate map zooming, and repeat spoken-voice prompts. An antenna is built into the top bezel, and...

The Cobra NavOne 4500 features a large screen, an accurate receiver, and a quick satellite lock. It also has a traffic receiver, but you must live in a serviceable city to take advantage of it.

The Cobra NavOne 4500 occasionally suffers from slow route calculations, and it's heavy.

Real-time traffic updates, highly detailed maps, and a beautiful 5-inch color touch screen give the Cobra NavOne 4500 bragging rights as one of the hottest vehicle-navigation systems around.

Cobra NavOne 4500 GPS arrives for Review at the GPS Lodge


The Cobra NavOne 4500 car GPS arrived for review at the GPS Lodge, and wow is this BIG. It is strikingly huge with its bright 5" screen and is heavy look and feel. The design is somewhat retro with its chrome trim and its sharper defined edges. ...

Works great and has lots of features.


Had a great working 4500 for over two years. Cobra came out with a 5000 and as usual I just had to have the new model. ( big mistake ),Cobra let this one hit the market before it was ready. I had nothing but trouble with it. After two mailings back to...

Well built, large screen, tride and true GPS

Wish cobra had not dropped the altimeter feature in latest generation of the 4500 model, I liked that feature in my older 4500

Real Time Traffic attachment connection is very flimsy


I was very excited when I brought this GPS system. The large display and the realtime traffic was the biggest seller for me. However this device has been nothing but a disappointment. I had to send it back to the factory for repair after using it for...

Large screen for GPS

Routes needs to be updated. Many address not found. Real time traffic feature is great when it works

Nothing Beats Knowing Where You're Going!


I have used a few GPS units for in-car use. None are perfect. Some built-in units require CD/DVD maps - totally suck! Some keep telling you to U-turn if you deviate from suggestion (they suck, too). None are always right. Most never get street numbers...

Large screen, usually loud enough, usually bright enough, corrects itself with grace, location by phone number, free updates, traffic re-route, no mp3 & picture BS

Heavy, makes errors, no battery backup for hand-held use, gets confused in government-controlled areas (DC & Norfolk)
