Garmin has announced slick new additions to its nüvi line of personal navigation devices with its 3700 series. Available in three models - the nüvi 3760T, nüvi 3750 and flagship nüvi 3790T, the slender units are just 9mm thick and feature a 800 x 480 pixel, 4.3” WVGA glass display with capacitive multi-touch functionality that lets users zoom in and out of maps by double-tapping or pinching.

Maps and menus can be viewed in landscape or portrait mode, the view can be changed from 2D to 3D perspective and maps can be rotated 360 degrees using a two-finger drag or twist. There's also a screen lock for when the device is nestled away in your pocket.

Garmin says the 3700 series features the "highest sound quality in the nüvi lineup" courtesy of a secondary speaker located on the powered suction cup mount. The 3790T also adds a customizable “wake-up phrase” which is used to start voice-activated navigation so that your attention need never leave the road (or sidewalk).

Other key features include a speed limit indicator for most major roads, lane assist with junction view (a big time-saver on complex freeway systems), auto-adjust time zones, optimized routing via the company's trafficTrends™, myTrends™ and ecoRoute™applications and a "Where Am I?" function which locates nearby hospitals, police stations, gas stations and the like. When on foot, cityXplorer content assists with getting about using information on local bus, tramway and rail systems.

All three models measure 4.8"W x 2.9"H x .35"D (12.2 x 7.5 x .89 cm), weigh 4 ounces (113.4 g) and have up to 4 hours battery life.

Pricing starts at US$349.99 for the nüvi 3750, the nüvi 3760T costs US$399.99 and the 3790T costs US$449.99.
