I came from another GSP and I really liked the beep notification before the intersection change.
When I was approaching a turn in an intersection, I would get a beep a few feet ahead. It is extremely relaxing, I find, to be notified before a turn.
On the other hand, it's extremely frustrating to have to constantly look at your GPS when you do long rides of 300km and more, and extremely irritating to have a beep 100-200m later.
Is there such a notification option on the Garmin?
