I Have A Garmin Gps. How Do I Upload The San Disk (sd), Which I Purchased?
Put the card into the GPS receiver. There should be a slot on the side of the unit for the card. Just slide it in. If you have an outdoor handheld unit that does not have a slot on the side, open the battery compartment, remove the batteries and look behind the batteries for the slot.
To upload maps to the card, either copy the appropriate files using Windows Explorer (the GPS receiver will appear as a removable drive) or use whatever Garmin mapping program you have to send the maps to the receiver.
