A simple problem to solve: just use the webupdater with a Virtual Drive with Garmin folder and GarminDevice.xml of the nuvi 140/150T. The GUPDATE.GCD is downloaded in folder .System created by WebUpdater. Additional updates can also be downloaded. As we do not know which the first version of the firmware installed is desirable, but not mandatory, to change it to 1.00 or below in GarminDevice.xml
