Garmin to Magellan
With this program all types of the maps can be uploaded to Magellan mapping receiver via serial port (primary and secondary basemaps, detailed maps). Magellan GPSRs have 2 different protocols for the PRIMARY basemaps (for 2 MB receivers (Green/Yellow) and for the others), both of them are supported by the program. Normally the program automatically enter to the map upload mode; but if control to the receiver is lost (i.e. there is some error in the *.img file) map can be uploaded from the hidden menu (98) mode("!" button). Upload flow can be controlled with "debug log" window.
Select PORT settings, or "auto", select file to upload, select type of the map, press "Send".
