The Garmin Garage
If you are not crazy about the vehicle that represents you on your Garmin 770, head over to the Garmin Garage and find something that is a little more "you." There is a large variety of options from which to chose, such as "Walkin' Scooter," a happy, stout little guy, to "Mud Slinger," a wheelie-popping dirt bike and everything in between.
To download a new vehicle, connect the Garmin 770 to your computer. Find the vehicle you want and click on Download. Click Open from the download window and then click Extract. Once it is extracted, navigate to the Vehicle folder on the Garmin 770. Unplug the Garmin 770 from the computer. Touch Settings on the Garmin 770 and select Map. Choose Vehicle and select the vehicle that you downloaded.
There are other downloads available for your Garmin 770 on the Garmin site, as well. Check out the Bundles page, from which you can select downloads that include multiple vehicles within a specific theme. For example, download the Service Vehicle bundle and you get a wrecker, a taxi, an ambulance, a school bus, a fire engine and a police car.
