This review is from: Nextar C3 3.5-Inch Portable GPS NavigatorI'm not sure you could do much better than this for the price. I bought it on sale, more than a little anxious about the quality of the resolution, the touch-screen interface, the accuracy of the GPS, etc. I have been VERY impressed with this unit.One of the things I like best is its built-in rechargeable battery. This precludes the necessity of having cords hanging all over your dashboard, and is a very nice touch. The battery lasts well over 3 hours on a single charge (I drove for 3.5 hours once on a charge and 25% still remained), and both AC and DC/cigarette lighter adapters are included for charging at home or on the go.The 3.5" screen is large enough -- and resolution clear enough -- to allow easy reading as well as a good bit of detailed information to be displayed at any one time. The touch screen is easily calibrated and remains quite accurate. Even when typing in letters for a street name, I seldom "fat finger" a virtual button. The display is bright and crisp, and easily readable, even in bright (indirect) sunshine. I use this in a SUV with a sunroof, and also in a car with t-tops and even with the tops out on a sunny day, it's easy to read the display -- and that's not even at its fullest brightness! There is an "auto" setting that will dim the display automatically at night... nice touch. Colors on the display are good and saturated and contrasted appropriately (you can change the overall background or color scheme between four different colors). Viewing can be toggled between a regular view and a "3D" angled-type view in one of three different angles. You can also select whether you want the orientation of the map to be "north" (where north is always up) or "heading" (where the map turns as you drive so you're always moving towards the top of the screen). At any point in map mode, you can "pan" by touching and dragging the map. Very cool.The flexible holding arm attaches to a cradle and terminates in a rock-solid clampable suction cup. Not once -- even going over rough railroad tracks or off-roading in the Jeep -- has this suction ever broken off my windshield in days and days of continuous attachment. An adhesive-backed disc is also included for dash mounting (you would then suction the arm to the disc). One nice touch is that the GPS unit itself is very easily removed from the cradle... good for security when you're out of your car.The excellent Navteq software is Windows CE-based.The GPS signal acquisition takes a couple of minutes from a cold start, less from a warm start (if the unit has been turned off, then turned back on in a short while). I'd call the acquisition time slightly better than average of the GPS units I've used. Once acquired, however, this unit is VERY accurate, typically even locking in signals from 5 or more satellites while indoors. Both the maps and the displayed speed are right on the money, and the turn-by-turn navigation instructions (delivered audibly and visually) are accurate as well. The voice used is smooth and reasonably clear (female voice). You can set the unit to provide all kinds of routes... quickest route, shortest route, routes using or avoiding major roads when possible, routes including ferries or toll roads, routes using or excluding HOV lanes... goodness. When navigating, if you miss a turn, the route is recalculated within a few seconds. You can also look at a route list and avoid a specific road on the list, after which the route will be recalculated.Points of interest are numerous (1.6 million) and highly usable. There are shortcuts to the more common POIs such as restaurants, ATMs, gas stations, etc. By touching any of these buttons, the display will show you the nearest POIs sorted by distance from your current location. You can also store favorite locations and a "home" location for easy retrieval. Navigation to any of these points, once selected, is as easy as touching one button.There are some pretty neat ancillary features as well. Of course you can display everything in standard or metric measurements. The GPS info screen shows you the signal strength of each satellite from which a signal is being received as well as your exact latitude and longitude (with a minimum of 3 satellites' signals locked in), altitude (minimum of 4), and speed. I wish you could display the altitude on the main mapping screen, but that's not an option. I'd rather see the altitude there than the time. Perhaps that could be addressed in a firmware update? :) You can set a "speed alert" as well, to warn you if you exceed a preselected speed. You can even choose "auto speed," which uses the type of road you're on to determine the most likely speed limit. Not sure how useful this is, but it's a neat option.Incl...
