The Good The Dual NavAtlas XNAV3550 offers text- and voice-guided turn-by-turn directions and has an excellent points-of-interest database. The unit also features turn signal indicators and multimedia capabilities.

The Bad The user interface of the map screen can be quite confusing, and the XNAV3550 can be sluggish at times. It also doesn't support text-to-speech functionality or traffic updates, and Dual doesn't include a dashboard mount or AC adapter in the box.

The Bottom Line Though the Dual NavAtlas XNAV3550 could get you from point A to point B, you can get a simpler system and better value with other in-car GPS devices on the market.

Dual NavAtlas XNAV3550

Dual Electronics is certainly no stranger to aftermarket car tech, offering plenty of audio and video solutions, such as the Dual XDVD8182. However, it's pretty new to the GPS game, and judging by its Dual NavAtlas XNAV3550, it still has some things to learn. Dual NavAtlas has its highlights: basic navigation features like text- and voice-guided directions, automatic route recalculation, and an excellent points-of-interest (POI) database; multimedia features; and a nice design with innovative turn indicators. However, the map interface can be confusing, and the system responds sluggishly at times. Plus, there are some omissions that may seem minor--such as the lack of a dashboard mount and a USB port--but when compared with other similarly priced systems, they become major omissions and make quite a difference when deciding which to purchase. That said, at $499, we think you can find a better value in the Magellan RoadMate 2200T or the Averatec Voya 320.


Upon first glance, Dual NavAtlas XNAV3550 looks to be a relatively attractive portable navigation system, save for two nubs that stick out on the left and right side and detract from the overall streamlined look of the device. Despite being an eyesore, the nubs are there for good reason, which we'll get to soon. The XNAV3550 measures a compact 5.2x3.3x1.2 inches even with a flip-up GPS antenna on the back, and it weighs a light 6.8 ounces for easy portability between cars.

The Dual XNAV3550 features a 3.5-inch diagonal, 16.7 million-color touch screen with a 320x240 pixel resolution. By the numbers, the color output and resolution are on par with other top in-car GPS devices, but we found the XNAV3550's display just slightly washed out and not as sharp the others. It was generally fine for viewing maps, however, and we were still able to read the display in sunlight. Surrounding the screen are four buttons that allow you to go to the main menu, turn the display on or off, and zoom in or out of maps. The controls are large and tactile for easy operation. We wish we could say the same about the onscreen keyboard, but it's actually quite cramped, so save yourself the trouble and use the included stylus on top of the unit to input addresses.

As we were checking out the interface and overall usability of the Dual NavAtlas XNAV3550, we couldn't help but think that we've seen this device before. We then realized it was the same interface as the Delphi NAV200, which makes sense since they both use Navigon software. This wouldn't be such an issue if the map screen was easier to understand. As we noted in the Delphi review, the navigation page is overwhelmed with tons of information and unidentified icons. You can hide some of the information, but it still can be very confusing. You'll definitely want to give the user's guide a thorough read and spend some one-on-one time with the unit before heading out on the road.

On the left spine of the unit, you will find the power button and a 3.5mm jack that accepts Walkman-style headphones, while there is a volume controller and power connector port on the right. Now, as we promised earlier, we'll tell you about the two nubs that adorn the left and right sides of the XNAV3550. They are actually turn signal indicators, and each one will light up to indicate the direction of your next turn. We've never seen this on a portable navigation device and we quite enjoyed this feature. Sure, you get text- and voice prompts, but the extra visual indicator is a welcome addition.

We were pretty disappointed by the accessories that are packaged with the Dual XNAV3550. These include a 1GB SD card preloaded with maps of the United States, a windshield mount, a carrying case, a car charger, a DVD with additional maps (Canada, Hawaii, Alaska, and Puerto Rico), and reference material. First, the vehicle mount is only for windshields; there is no dashboard option like the one provided with the Delphi NAV200. In California and Minnesota, it's actually illegal to use windshield suction mounts while a vehicle is in use, so drivers in those states, or anyone who wants to mount the unit on their dash, will have to purchase the adhesive disc as an optional accessory. Also missing is an AC adapter. Sure, this is largely an in-car device and a car charger is part of the deal, but if you're trip-planning at home or using the unit's multimedia capabilities, having that extra power source is key.
