FAQ: Are there special key combinations I can use?Yes, there are. If you press the following combinations while turning the power on, you get access to special screens/functions:
 | + : Show the diagnostic screen (shown here on the left)
+ : Erase all user data
+ + : Factory reset, erase all user data and the GPS almanac (does not function in firmware 2.12beta and higher)
From a mail I got from Robbie Kay: Here's the reply I got from Garmin about the master reset: The Master Reset sequences are being removed from our units (they can damage the GPS receiver board if used too often), and we can only perform them via a software application. I believe the latest version of the GPS V's software does not have a Master Reset sequence.

This will only work when you have a waypoint named "HOME" though, even when the V is set to another language.

Another shortcut is to press twice to get the backlight on, where once only displays the backlight/contrast menu.
