My company has a fleet with eight Nuvi 50LMs. The two most recent updates, "nuvi 40 and 50 Language Text" and "Proximity Alert Text, All languages, GLX" download and install just fine, at least according to Garmin Express. But when I plug in the GPS to the PC a 2nd time, Garmin puts the updates back as if they weren't installed. I tried installing a second time, and closing/reopening Express, all to no avail.
This has happened to all eight 50LMs. Any suggestions?
Thanks,
