For most manufacturers of consumer electronics, it's sometimes a lot more profitable to come up with various devices that are based on a common, proven and reliable technological platform rather than keep on innovating and launching new and improperly tested designs. And that's exactly the case with the Nextar company, who launched a triad of GPS navigation devices, namely the W3, W3-01 and W3G models, that share the same platform with only a few minor design differences.
Thus, all the devices from the W series have been fitted with 3.5-inch touchscreen TFT LCD displays, which provide a 320 x 240 resolution. The screen can be used as a control interface but also for displaying the navigation maps in either 2D or 3D viewing modes, as well as day or night modes (the night mode sports additional screen lighting for easier viewing).
And since we're on the subject of navigation, it's worth mentioning the fact that all the devices in the W series from Nextar come packed with some pretty detailed maps of the United States, including 1.6 million points of interest. Moreover, the device sports an address book that can store up to 300 addresses, as well as a stereo system for providing the voice-guided turn-by-turn directions.
The PNDs from Nextar's W series also incorporate a few interesting multimedia functions, since they're capable of playing MP3 files stored on additional SD cards. Moreover, the devices are powered by rechargeable Li-Ion batteries, but, unfortunately, the manufacturers don't offer any significant information about the provided functioning life.
All the models from the W series retail for less than 500 US dollars, which could be considered some pretty high prices to pay for these devices, especially considering the fact that their reliability and quality is not exactly a certainty.
