Fault with Garmin software when deleting files via USB mass storage on 37xx series. Plenty of info about it around. Just google.
Solution: Need to pull the usb cable to disconnect. Dont use the windows safe disconnect feature (that is the problem).
There is also a fault with alert settings when more than one personal POI is installed on 37xx.
