hi is it possible for this unit to pre warn you, if for example your heading on a course to hit a rock, or a preset shallow depth? or do i have to keep watching the sceen while im driving fast on my boat? And is this unit automatically updated for my waters, or do i need to download some updates?
You’ve posted this in the Garmin Connect forum which has nothing to do with your query. Sorry but unfortunately as yet there isn't a forum here for device issues like this. Please contact Product Support
