Garmin Maps | Cloning Method: Install a Map Update Directly to the SD Card.

Garmin Express and GarminMapUpdater include methods for installing maps to a SD card for most, but not all devices. The cloning procedure described in this FAQ works for those devices not supported by the Garmin programs, namely the nuvi 3xx, 5x0, 6xx, 8x0, 8x5 and 5000 series (and perhaps others).
1. There are some other advantages to using the cloning method. These include:
You can perform the map update process without affecting your device. If something
goes wrong with the update, you still have a working GPS with the old map.
2. The map install process will be faster. This is because it installs through your
computer's card reader which is a much faster device than the USB port of your Garmin device.
3. If you keep multiple map versions on separate SD cards, you can easily test the new
map and revert back to a previous version with simple card swapping. SD cards are
cheap. Keep your old map SD card until you are sure the new map is OK.
This method will work with the older Garmin nuvi and zumo devices including the following model series.
nuvi: 2x0, 2x5, 3xx, 465, 5xx, 6xx, 7x0, 7x5, 8x0, 8x5, 5000
zumo: 450, 500, 550
