Hello, until Catymag answeres to you, let me add that I used this method several times... with Garmin folder on EXTERNAL SD card, the card out of phone into the card reader, and all garmin programs (mapsource, basecamp and webupdater) see the card as a garmin device. The simplest way (that I do) is to have a Garmin folder on a usb stick, in this folder you copy the garmindevice.xml file. Hope to be of help.
