Your Garmin help, please

This was forced onto my device last night...

Changes made from version 5.20 to 6.00:

Added support for Varia Vision. Pair with this sensor by turning it on and adding it by selecting Settings > Sensors > Add Sensor > Varia Vision. Choose it from your list of sensors to configure its display settings and data screens.
Improved stability of ANT+ and Bluetooth connections to address dropout issues.
Improved navigation by leveraging enhanced map data in 2015.30 cycle maps.
Added the ability to automatically download software updates over Bluetooth. You will be able to download the next software update after this one by pairing to a smartphone with the Garmin Connect Mobile app. Updates can be installed when you are prompted after they are downloaded. If you choose to wait, a ready-to-install update can be found in Menu > Settings > About > System > Software Update.
Fixed an issue causing some manual activity uploads over Bluetooth to fail.
