We purchased this unit especially for the large screen. As to previous comments: The manual is cursory at best and no additional information is available on their web site. The manual does state that you should moisten the suction cup before installing, and that you should allow the unit to actually rest on the dash. Following these instructions, we have never had the unit come loose, even on bumpy mountain gravel roads. There has never been a problem with overheating, and wrong turns have been minimal. As previously stated, it does get you there.

Approaching required turns there is a "countdown" bar on the right side of the screen that gives you plenty of warning prior to the "two dings" of the chime for the actual turn. If activated, another feature provides you with an expanded diagram of the approaching intersection or freeway ramp. User preferences are very easy and intuitive to find and change.

The unit has served us very well on at least three extended trips; one to Alaska, One across the country and back, and another from the west coast all the way east to Prince Edward Island in Canada.

On one trip we activated the 6-month free city traffic receiver program that comes with the purchase. It worked very well in all the major cities that we visited.

Another thing a user should know is that there is a need to periodically update the unit. This fixes many known "glitches" and provides database updates. Downloads are very easy to use from their web site, and the site should be checked for new updates every month or so. There is also a "pop-up" reminder in the GPS that periodically advises you to check for updates. For one large update they sent me a free CD. The software appears to be provided from Tom Tom. So far there is no cost for this.

Telephone technical support has always been fast, courteous, and accurate. A BIG plus these days. We could have saved some calls, however, if the documentation was more extensive and informative. This is the main reason that we gave it a four rating, rather than the maximum five.

We have a Toyota Highlander with the built-in GPS. Toyota recommends updating the unit every six months - at a charge each time of $200.00 for the DVDs and plus an hour of labor if you can't install them yourself. So for the update cost for one year - $400+ we can purchase a new unit. I can honestly say that the Cobra unit is easier to understand and operate than the Toyota unit. The Toyota feature that prevents a passenger from entering or changing routes while moving is a MAJOR inconvenience. We plan to buy a new "portable" unit for the Toyota and ignore the installed unit.

One anomaly that has yet to be fixed is somewhat strange. In Canada, about 60 miles north of the US border, the "time to go" reduces the time by 50% (time to go becomes half of what it should be). This happens whether you are using kilometers or miles and continues until you return south of the offending latitude. I have brought this to their attention by email and telephone, but still no fix.

It would be nice to have an internal battery but it isn't a big issue for us. With the supplied AC and DC adapters I can program or reprogram the unit in the vehicle or inside at any time. I often enter planned routes the night before by using one of the adapters. The unit usually receives the satellites quite well inside as long as you are near a window; but you don't need reception to program it. For walking and hiking we purchased a very nice, hand-held, Garmin battery powered unit.

It is a very good unit and has served us very well. I highly recommend it, however, it is becoming a little outdated compared to some of the newest model GPS units. Still a bargain at the current price.

I purchased this product over three years ago, and I am pretty sure this is the best unit out there.
It's rugged (I've dropped it several times, with the dents to prove it).
You can set via points easily to change your route to the one you prefer. This unit, like all others (including web-mapping) many times doesn't pick the best route for you, which is definitely a factor for long-distance trips. I usually use Google Maps to first plot out my route, and use via-points to alter the suggested route (if necessary) of the NavOne. A via point is a point along your route you want to travel through, so by telling the NavOne that you want to go through a particular point, it will recalculate the best route, based on passing through the via point you set. You can set up as many via-point as you wish, in order to achieve the exact route you want.
The unit has another screen you can view, showing many statistics of your trip. Current, average, and maximum speed, altitude, time, compass direction, and many others are available to display (but only 4 of these can be displayed simultaneously).
The display will automatically darken at dusk, eventually switching to a nighttime display that's easy on the eyes.
My biggest complaint about this unit is the mount. It is the crappiest mount ever for such a great unit. It's suction-cup based, and I've had the mount fail many times, sending my expensive unit plunging to the floorboards of my vehicle. I eventually used clear silicone adhesive to semi-permanently affix the mount to the windshield of my Jeep Liberty. When I use it in my Nissan Titan, I have Velcro adhered to the bottom of the unit, and affix it to a wooden stand which fits in a niche on the dash. I just rented a car for a road trip and used foam mounting tape to affix it to the dash and windshield.

So far I find the Cobra unit is very accurate and has all the features I need. I like the large screen and voice directions. The only problem is I can't get an additional windshield holding mount. So I have to move the holder from vehicle to vehicle. Cobra does not offer additional mounts for the 4000 unit. Overall for the price it is an excellent buy.

I just had this over the weekend and only payed 125 so heres my thoughts. For what I paid for it I can't complain about what it is/isnt. But if I would have sunk any real cash into this I'de be sending it back. This is a very good sub $200 gps. Heres what you should really know. It has speech. but limited text to speech. So basically if you want a gps to tell you all the street names.. Not happening here. I added all the updates when I got it so I can tell you the 3d graphics.. like you see now on most gps's (like tomtom) is not as good. also you really have to clean your windshield
before you stick this on your dash. I had it come off the glass 2x already in 3 days. It is a pretty hefty item to hang from a suction cup.
I ended up placing it so it actually rests on the dash while attached to the window.
Good points. The screen auto adjusts to the daylight/or lack of
the navigation is spot on. with the update installed I dont have the problems others have/ I had the updates on before I ever test drove it.
The voice commands are clear but mechanical sounding female voice. You would think the a gps that actually has a microdrive inside could have added other voices to the package. I got the database update. so I can not comment on how the new maps compare to the old. But the last update is 2006 and its close but not perfect. One quirky thing about this is it has modest actual street address finding.. It will list roads when it can not find the actual address. in a couple cases it says "no data" this is no big problem just annoying. for what i payed for it its great. The 5 inch screen.. 4.4 actual inches and a icon strip on the side is a lot easier to see than the tomtom go. May not mean much to you younger people but when you get older this is a selling point. If you can latch onto one cheap its a 4.5 at +200 a 3.5.

I forgot to add with the updates. it doesn't jump page to page like mentioned in other reviews.. it moves along just like a tomtom.

Not worth any amount of $$$ - You will get lost if you use this!!!

Bought this unit for the big screen size and some other reviews that I had read. What a mistake. The unit operated for a few weeks OK with the turn by turn directions a major plus. However, after the initial break in period the unit lost all inputed memory which wouldn't have been a problem for me, but my wife was on business trip and she can't read a map from a Victoria's Secret catalog. Anyway, she lost the home memory function and manually inputed our address. After traveling 3 hours she was directed to the middle of the state, about 2 hours from our house where she called me and I was able to help her get home although she was 4 hours and 300 extra miles late!

Went to the Cobra website for FAQ's about the problem or maybe a software patch, which there was one for this unit from 2 years ago, later than what I had installed, downloaded it, installed it and next time we stared the car there was a loss of internal memory and the unit stated in the welcome screen that there is possibly an update to the system memory. Called Cobra tech support, they told me to send it back and they updated the BIOS and installed the same update which I had done previously. This worked for 2 days with the same result after that with all loss of inputed memory.

In summary if you want to buy this product you should be pretty sure of the warranty and possibly what the return restrictions are as some stores won't accept returns of used GPS units.

If all the inputs you made to the memory drop off and you can't retrieve it don't even hesitate and call Cobra support at 773-889-3087 to ask how to return this model as it seams they can't even fix it.

So don't waste your time and hard earned money, buy another brand.
