I can confirm that in Firefox 6.02 the map control labels are not being displayed. If I hover over the controls it will show the choices and I can click on these buttons to change the view but the labels are not being displayed.
How to fix Garmin Connect and bring back Google Maps
Mozilla Firefox:
Install Greasemonkey Install Garmin Connect Google Maps
Yeah, I had that greasemonkey script installed but since it doesn't change the Player map I uninstalled it. Gfix doesn't change the maps in the Player either though, so maybe it's not that simple to do. In my email to Garmin, I took the opportunity to complain (politely) about the switch to Bing. The response was very obviously a canned response that had been sent MANY times :(
