Below is the answer I posted in response to the question “Will nav systems on cars  become commodities or will they be replaced with apps?” on Quora.

I believe we will see cars become just another ‘device’ that connects to the cloud. So navigation (and many many other things) will just become apps accessed through your vehicle.

I think there are greater prospects for multi-modal inputs (voice, touch, gesture, etc) inside vehicles and hope to see the future taking advantage of these prospects.
