Map data transfer requires installation of Trip and
Waypoint Manager and the USB Interface Cable
to transfer MapSource data from a computer to the
microSD card in the Astro 220. To transfer other data
to the microSD card, use the USB Mass Storage feature
explained on page 68.
You can purchase high capacity microSD cards at your
electronics supplier or pre-loaded MapSource detailed
map data cards from your Garmin dealer. See the Garmin
Web site: www.garmin.com/cartography/
MapSource products.
Use Garmin MapSource for transfer of both your own
and your dog's tracks from the Astro 220 to MapSource.
Highly detailed dog tracks can be transferred from the
DC 20 via the Astro using the "Transfer Dog Unit Track"
option from the Dog Info page Option Menu.
To install or remove the microSD card:
1. Remove the Battery Compartment Cover from the
back of the unit and remove the batteries.
