I thought I was going crazy: trying to start navigation by voice would answer "Let's go!" and then do nothing. It had to be my unit! Who would be so bad not to find an issue like not being able to navigate on software <i>made to be used in a car</i>!<p>Turns out: Google! There is a known issue - now ongoing for over a month - that prevents users from starting navigation using the assistant.<p>The workaround? Unplug the device, set the destination on the phone, plug it back in. Now, try that with wireless Android Auto.
