I have the App, but I seem to be having a problem with navigation. I can be at a (known) given location 75 miles from home, plug in Go Home and the calculation appears. The map shows my progress as I drive home, but the sequence of turns, distance to turns, distance to home and ETA never appears. The route list seems locked on the right even though the vehicle on the map is shown as moving. I also hear no vocal guidance even though I paid for it and have it installed. There are no instructions that I can find in the manual that tell you how to trigger the start of the navigation process.
