One thing I'm exited for is using the voce guided turn by turn on my motorcycle. Up until now I have used the tomtom app, but inputting addresses and finding points of interest in tomtom is a real pain. I use a Bluetooth kit in my helmet so I can get interact with Siri and hear directions just fine. My question is can I ask Siri for directions and have the routing start without having to physically touch the phone? For instance. Could I pull my bike over, activate Siri and say "give me directions to my brother's house" and have the turn by turn kick in without having to interact with the screen?
