Using the current Garmin Express (for Mac version 7.20.0.0) the software, Express offers to update the timezone map on two different devices without success claiming there was an error installing the update (e.g. D2 Delta and D2 Delta PX). I followed all of the online help / suggestions including reinstalling Express without success.
More detail. Tried updating through Connect on an iPhone, which claims to have updated the D2 Delta. Back on Express now it shows downloading the file and updating, showing update complete in green. Just to sync and show the update again.
This all with the most recent version of Express for Mac 7.20.0.0. My take is that a bug was introduced into this version.
Thoughts?
