Pass......Amazon's going Echo crazy with an Amazon Echo for your car, teamed up with Garmin to provide navigation, and other Echo functions.
I already have a nav unit in the car and don't want to use up cell data for this.
If there was a way for it to use the voice function to play music on command from my 128GB USB stick that's plugged into my head unit, I might bite. That would be kind of cool and useful for me.
