Well I went back into MyGarmin and then ran the Garmin Map Updater v3.1.19 and then selected Central and Eastern Europe. The current estimated install time is 2 hours. I'll see what happens.
I have flailed around with Garmin Map Updater, Garmin MapInstall, and Garmin Lifetime Updater. If this works I'm relatively sure I can't repeat what I have done.
Is there any reason why this needs to be so painful?
