Garmin trotted out its latest line of nüvi navigation devices at CES this morning, including the 3590LMT. This ultra-thin device was on display at Pepcom this evening, sporting sleek curves and a commodious five-inch display. With the 3590LMT, users get access to Garmin's Digital 3D Traffic feature, giving them access to both real-time traffic updates and historical data. Joining the 3590LMT is Garmin's dedicated Smartphone Link app for Android, which provides users with the latest fuel prices, allowing them to plot out the most fuel efficient and cost-effective routes. The app is available for free, but the 3590LMT, unfortunately, is not. It'll hit the market next month, for about $400.
