Good News! ( for us Android users ); I just found out that the "Cue Sheet" app has been updated. Seems there is now a "Pro version" ( $3.99 ) available as well which can do voice prompts. I just upgraded to the Pro. Can't wait to see how this works. Sadly, if it works great it will mean that I will no longer need the Garmin.

Crossing my fingers hoping this app will do as it says. If it works I will sing it's praise.
Looks like I too might be in the market for an external battery ( if this app works )
