Dual XNAV3550

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 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.

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.
