audio prompt for next interval

Is there a way to get my head unit to count down or give three beeps to warn me of the start of the next interval?

I hate having to always look down at the head unit wondering when the next interval will be.  Of course, the other part is knowing what am I ramping up or down to.  It's hard to read the little description at the top of the screen while not crashing into something.  It this part is not that important when the intervals are greater than a couple of minutes as I have time to glance down and see what the targets are.  But when I am supposed to do an all out sprint for 6-20 seconds, I don't want to look down.
