I've actually had two Cobra NavOne 4000 units. The first developed an over-heating problem which caused the screen to blink rapidly on and off and which was accompanied by the acrid smell of burning plastic and metal. This behavior only manifested after 32 days by which time technically the unit was out of warranty coverage. Fortunately [...] took the return and I was able to get a new unit. I'm hoping the new unit will be defect-free but it's too early to tell as of mid-March 2007.Other than the defect problem, the unit is great. The screen is larger than most after-market units, though the claimed 5 inches isn't accurate: because the right-hand and upper borders are used for soft keys and metrics, the actual map size is around 4.5 inches. This is still better than most units available and makes it easy to read. The set-up and system navigation is intuitive and you don't really have to read the manual at all unless you want to get to the special features like customizing your display. The voice guidance can be a little irritating (for example, you're already on highway 101 and as you approach an intersection it says "get onto highway 101" instead of "stay on highway 101") but it's generally useful and accurate so long as you ignore the idiosyncracies.Many OEM navigation systems keep the vehicle cursor centered and scroll the map around the cursor, which makes it easy to glance down and locate your vehicle. The Cobra NavOne unit, alas, scrolls the cursor and then "jumps" the page when the cursor nears the edge of the screen. So you have to scan the map to find the cursor again, because it can reappear pretty much anywhere depending on the new page layout. This can make dealing with intersections really tricky, because as you approach your turn-off the map suddenly jumps and you have to try to find the cursor while at the same time watching out for merging traffic, other cars trying to exit, and all the typical bad driving that often accompanies any highway interchange. This is the only major flaw with the way the unit is designed (assuming you can live with the retro chrome styling of the unit itself).I particularly appreciate the fact that you can set up trails and waypoints with this unit. I acquired it for use in my four-wheel drive and as I frequently go off-road into unknown territory I like the breadcrumb feature that ensures I will always find my way back. If only the unit had a small capacitor or battery to store charge in the event that the vehicle's electrical system temporarily goes down, it would be perfect.

The perfect travel companion

I purchased the NavOne 4000 for long distance travel but I often find myself using it just to find places around town. You're presented with a large 5 inch touch screen display, which is perfect for easy viewing. The only downside is you'll never want to use another GPS unit with a smaller size screen. The maps are accurate but they won't have every "new" road from recent construction. This is to be expected and Cobra says they're planning to release updated maps sometime during the summer of 2007. (Keep in mind this is a tentative release date.) The user interface of the Cobra is really easy. Not needing the user manual, I found it easier just to go through the menus myself. Over all this is a great unit. I would say its only downfall is its greatest selling point being, "it's big." Depending on the size of your windshield you may find that it blocks too much of your view. I really enjoy having my Cobra. The feeling I received when I gave all my maps and road atlas away is great, and the reassurance of having a good navigator makes it worth every penny.
