I've done a lot of searching around, but I'm coming up short with this.... I'm looking for a GPS app that does both turn-by-turn directions as well as a "Live" GPS map. I believe "Live" GPS is the correct term. I want to see an overhead map view with my GPS location, following along as I move. I'd also like to have a little window showing my speed and possibly the time as well. Are there any apps on the Hero that will do this?
