The 480 does this as well (in addition to going "ding" at the turn now

Yes, that would be a nice feature. It is somewhat distracting to have to
look down at the unit. However, the count-down feature is nice, since one
look at the GPS and the count-down can be taken over mentally.

It's even more fun if you have a GPSS autopilot. Watching the thing
fly the holds and PT's by itself always amazes me.

My aircraft is also equipped with GPSS so this feature will be interesting
to test and eventually use.
