Quick answer

Use a short, good USB cable, ideally the one from the phone box, and check that Android Auto is on in the car. On the phone, open Settings, Connected devices, Android Auto, check Start Android Auto automatically and Start Android Auto while locked, and forget the car and connect it again.

Watch these steps Done
Check how it starts
Start Android Auto automatically decides whether it opens when you plug in. Ours was on Default (set by the vehicle).
Done
Allow it while locked
Start Android Auto while locked lets the car use the phone without unlocking it first. It was on on our phone.
Done
Forget the car and connect again
Your cars are listed under Vehicles; Google's help says to forget them and connect again. Connect a vehicle starts a new connection. Ours had no cars.
Done
Change the cable
Google recommends a cable under 1 metre, no extensions, ideally the one that came with the phone. If it used to work, try a new cable first.
Done
Check the car
Android Auto must be switched on in the car's system, and the car must support it. Restart the car's screen and check the maker's list of compatible cars.
Done

About this guide

When Android Auto will not start, the cable is the usual cause, followed by settings on the phone or in the car. On a Galaxy, Android Auto's settings are under Connected devices, not in an app.
