Summary: This is my first ever negative review of any product. Pros: first affordable text-to-speech GPS. But that was 12 months ago. Cons: bad routing, lockup, software/firmware upgrade fix 1 issue and create 2 more, charge too much for map upgrade. Ask yourself: 1) will you ever watch video on your gps system? 2) will you ever listen to mp3 using your gps? 3) will you ever watch pictures using your gps? These are features you would most likely NOT use.
Summary: This is one of the easiest to use GPS I have seen. I love different languages and complete yellow pages. I purchased that unit just couple of month ago. The clarity of the screen is superb even in the regualar daylight. I can even play my movies that I download on my sd card. Sound could be louder but I put a jack from the unit into my tape player and now can enjoy full sound of stereo. Routing so far been just on the money.
Summary: Works just fine for me. I have used it for about 1.5 years and there have been no problems. If you are comparing this to a high end $250.00 or above GPS systems, yes, it falls short. But it is definitely usable for everyday purposes.
Summary: I have had the Worldnav 3100 premium edition about two weeks with no problems. Lots of features for the price. I'm sure many of the problems I read about in reviews were corrected with upgrades. The only negative I can see is the cost of a external antenna which cannot be purchased anywhere else.
Summary: I liked this product before but the new update has made this a real winner. When I first got my Worldnav I was going to Nebraska to visit a new customer, it got me there even with the last 6 miles of the trip being on dirt roads.
Worst purchase I ever made!...and i've made lots!!

Summary: This is honestly the worst purchase I may have ever made. I bought this unit in Dec'06 and have updated it several times (firmware) to no avail. It constantly hangs up, I have to constantly reset the unit, I have trouble finding the simplest locations. I'm basically going to give it one more try with the latest firmware update, if it doesn't get better I'll try to ebay it for $50.
Summary: WorldNav (version 4, Premium model) device is well constructed. It has a SIRF III chip set that makes my GPS lock in very fast. The screen is very clear and I could see it even during the direct sunlight. I took it on a 200 mile trip around the northeast. Voice instructions clearly pronounce the name of the street to turn onto, with just the right amount of time to make the turn. Routing is just about perfect.
