  • Montana 600 update via Express won't boot up.

    So I did a bad thing, I tried to update my trusty Montana 600 via Express for Mac. What I am left with is a Montana that gets about a third of the way through the reboot of the software update when powering on and then crashes. I have tried to reinstall the software via express with no sucess.

    Help! What do I try next???

    Go into the Garmin folder and delete the gupdate.gcd file, it's the update file. It's probably corrupted. Then try booting your Montana
