Just Open Box and Go

Navigate with Ease

The data card includes Garmin Mobile XT navigation software, City Navigator® NT street maps and a hefty points of interest database. Easily look up addresses and services and receive voice-prompted turn-by-turn directions to the front door. With 3D map view, automatic off-route recalculation plus more, you'll never ask for directions again.

Take It With You

The compact and portable smart mount combines a high-sensitivity GPS receiver, Bluetooth hands-free kit, adjustable phone cradle and 12-volt phone charger all in one. It easily adjusts to fit a variety of smartphones, and moves from vehicle to vehicle, making it convenient to take on business trips or vacation.

Make Hands-Free Calls

With Garmin Mobile 20’s wireless technology, you can talk on your phone safely via the smart mount’s built-in speaker and microphone. Easily look-up and dial numbers from your phone's address book or the extensive points of interest database — including hotels, restaurants, stores, attractions and more.

Enjoy Garmin Online™ Services

Get the most out of your smartphone and Garmin Mobile 20 by adding Garmin Online — free and subscription wireless data services for Garmin Mobile customers with Internet access on their phones. With Garmin Online real-time services, you can route around traffic tie-ups, receive alerts as you approach safety cameras, view the local forecast, find the cheapest gas prices near you, plus much more.

See and Navigate to Users

With Garmin Mobile 20's PeerPoints™ feature, you can text message your position to any other phone as well as view and navigate to the location of Garmin Mobile XT users in your group. Simply send your current position via text messaging to your Garmin Mobile XT partner's phone, and your location shows up on your partner's map page. PeerPoints is the perfect feature to keep track of friends and family at an amusement park, lake, or other outdoor group activity.
