I have been using my cobra gps for at least 6 months now and its great. has every place i've ever tried to find in the data base. if you need a trucking gps this is the way to go. Garmin and tomtom are paper weights. they will route you right to a weight limit rd or even to a tunnel you cant drive in with your truck. never had a problem with my cobra. you can even pull up a map on it and find your own route if you dont like the way it routed. makes my job alot easier knowing im not gonna get suprised by a low bridge or weight limit in my travels. If you have a garmin throw it out and get this.

Not always the best routes, but never terrible. I love the feature where I can set the height of my truck and it will take me the right way. Great in New York City where I can't remember the height of every bridge or tunnel. Big screen and very functional windshield attachment. It adjusts to many different positions so I can stick it to the windshield and rest it on the dashboard. That way the large heavy unit does not fall off. It would be perfect if I could enter my odometer reading and it could record my mileages for trip reports. Still excellent.

A large (7" diagonal) bright beautiful GPS that acquires satellites quickly, with excellent up-to-date street maps, and good informative screens, this moderately expensive GPS unit has some quirks you need to know:

Missing are next exit and next cross street information. Incredible.
So the only way to read the next cross street is to read it off the map where it may be sideways or upside down and keeps moving as you move. Awful!
Missing are miles to the next exit. That's bad, really bad.
So now I am running two GPSs, the Cobra gives me mile marker info, and another cheapo GPS tells me the next exit. Together I can figure out how far I am from the next exit. I should not need two GPSs for that.

To zoom in one step, you have to hit the screen three times. First to open to zoom tab, then to increase the zoom, then to close the tab. And all three hits have to be well aimed. Terrible. Unbelievable. Who designed this?
To see mile markers you have to keep a tab open - that covers up one third of the screen, and the screen does not recenter. So if you have North on top and travel east, you cannot see much ahead on the map. Ridiculous!
The mount is so completely inadequate (this is a big and heavy unit) that the unit shakes like bobble-head figures with every little bump, making information unreadable. Be ready to make your own dash mount.
Volume is inadequate for trucks.
The on and off button has to be found (there is no marking, you need to feel your way to find it) and has to be held down for three seconds or longer to turn the unit on or off - an eternity.

Routing - not tested. I plan trips on google maps.

The speed trap and traffic databases are notoriously unreliable for all GPSs. I do not use them. True to form, old local speed traps long abandoned still result in warnings, while major interstate construction that restricts lanes and slows traffic seem to be missed. These problems are the same for all three GPS systems I have. I don't hold this against this Cobra model.

The Cobra has other features like trucker log, duty hours, and miles traveled in each state. These are nice and work well.

Overall: a nice unit with some quirks and design oddities.

We have a 42 foot motor home that we travel across the country Full Time RVing. We have had a few different GPS systems, all automobile type mapping. Every once in a while the GPS will route us where we should not be because of weight or size. We bought the Cobra 7750 Platinum because of the Truck Specific mapping. You actually enter you vehicle specifications such as height, with, weight, etc. After entering this information, the idea is that the GPS will keep you on a safe mapping route so you don't have to worry about low bridges, narrow roads, etc. First of all, the user manual documentation that comes with this unit is a joke. It is a quick start, very basic information only. You can get a little, and I do mean a little better detailed one on line. Second, you cannot enter your destination as a latitude / longitude coordinate. It is set up for streets, POI's and destinations built into the user base only. If your destination is not in the data base, there is no other way you can find it. I had several addresses that were not in the data base. I did have GPS coordinate points but the Cobra 7750 will not allow you to enter them, so it would attempt to get an address as close as possible to the one you entered from its data base. Sometimes that was miles off. It also will not let you set up a route on another program such as MS Streets and Trips where you download it to the GPS, like I can in my Garmin unit. Nor can you download Custom POI's to the unit, like I can on my Garmin unit. Third, very, very, poor products support. I was getting errors when I tried to use the Truck version of the mapping program from time to time that would tell me to check trucking restrictions, but did not give me a way to check them. I called the help line three times. The first time I sat on hold for 10 minutes until someone from parts picked up the line. When I said I was on hold for the support line she said to hold while she transferred me but hung up on me instead. I called back and waited another 6 or 7 minutes until someone picked up the call. When I explained the problem to her, she said she did not know but that is a good question for another tech. She transferred me and I got a voice mail for the tech that asked for me to tell him what unit I had and what the problem was along with your name and number and he would call back. I waited 4 days, still no call back. That was it. I sent the unit back. I bought a Garmin Truck Specific GPS to replace this one. I have to settle for a 5" screen instead of a 7" screen but the Garmin is much more user friendly.

I'm going back to Garmin. After running the 7750 for a while I've decided this thing is junk, editing routes it gives is almost impossible, it routes my 18 wheeler to roads that don't exist, puts me on restricted roads where a big truck has no business going. Baltimore MD seems to be the worst place, this thing is terrible. I've been using the maps app on my phone as a backup for when the cobra gets lost. Don't waste your money, I hear the Rand McNally gps is doing a good job.

Piece if crap.Useless for a truck driver. 3 times in a week I ended up in a residential area with my 18 wheeler. It tells you that some of the truck routes are not for semi trucks which has been for years. Forget about newer areas, I had to use my cell phone to get to some of the bussineses which are in those places for couple of years.

I don't see what all the negativity is from RV'ers, apparently they don't or can't put in the specs of
Their RV. So no wonder it won't work for them. This
Thing gets me where I need to be & will tell me if the route wont work. Just put in the correct info & go!

This unit is amazing. The features it has such as the hrs log and duty log are very nice. Alot of people gave it lesser reviews because of the routing, the day I received this unit in the mail I called cobra registered the product and the sent me a dvd via mail with the 2012 map pack for free. I have had no issues with routing at all( I drive a 28 ft flatbed straight truck ). The POI were updated via cobra web site and are spot on. The screen is huge plenty big enough to see without straining my eyes. Yes the unit may be glitchy at first but after doing all the updates it works perfect for me. (edit) After almost 4 months of use on the road with this unit I can truly say that the gps unit is good...not great, but what has upset me most of all is Cobra's complete lack of customer service. I have never actually recsived the 2012 map updates that I was promised more than 4 times from them still waiting... and now the web site says "2012 map updates are now available" but when I click on the link I am redirected to a page saying that the content I'm serching for cannot be found. Calling Cobra has gotten me nowhere and I am ready to throw this $300 unit out of my truck window if it sends me through another small town instead of just keeping me on the freeway.

Good Points:

Distance to Rest Stops;
Nearest Mile Marker location;
Larger screen is easier to read

Not So Good My Friend:

ETAs are way off, even if indicating an empty trailer;
Visual display isn't the best;
Did not perform well recently in Eastern PA to include height recognition and routing;

I ordered this product on 7/31/2011; its now 9/6/2011 and I fear that it might be too late to return this item for an exchange with Amazon but I'll find out. I'd like to try the Rand McNally 710. I'll see about the exchange today. In the meantime, my Garmin Nuvi 465 replacement came in from the manufacturer. The 465 acted like it had a virus about a year after purchase; Garmin reviewed my claim, and the unit, and decided to issue a replacement. The Garmin Nuvi 465 outperforms the Cobra 7750 handlely but doesn't have the good points listed above. I thought it was time to try out the competitive products since I had to return my unit for replacement. Both are easy enough to figure out; you just keep pushing buttons:)

I bought this for my husband who drives all 48 states and right off the bat this thing didn't work out of the box. It wouldn't take programs or routes, it said there were no such routes or addresses, no such house numbers, and so on. I would not buy another cobra gps product for any amount of money. It was a total waste of money on this one. So buyer beware! Amazion customer service went way beyound what we expected from them, they were very helpful n understanding in makeing this situation right. Thank you Amazion!
