Agreed. I've tried several times to use google maps with bluetooth headphones on my bike in London. Unlike in the states, the roads are never straight for very long and there are lots of roundabouts. If you take a wrong exit, it will recalculate a new path, but without seeing the screen you don't know you messed up. I found myself wanting positive and negative feedback via audio. "Take the third exit at the round about." "Good job" or "Turned to soon. Recalculating"
