On my P30 I had to enable developer options and switch USB configuration from charge only to MTP while connected to the car. This allowed Auto Android to work. Switch back to USB charge only.

This should work as the Honor is basically a Huawei:

"Choose About phone, locate the Build number, then tap on it 7 times successively until you see a pop-up message saying 'You are now a developer' at the bottom of your phone screen".

Also, are you using the cable that came with the phone?

 

Hiya,

No I was just using a black micro USB cable that I had kicking about. Do you think that will make a difference?

 

It worked! Thanks, I tried it with the white cable, having switch the USB configuration, and everything is working.

Thanks for your help.

 

Android auto is a bit picky about what cable is used.

Not that it will only accept "quality" cables, i have had chinese "wish" cables that worked ok and more expensive cables fail.

I am still hoping someone will make a "cabled android -> wireless android"

Something like a chromecast that you can plug into the USB port and it will work as a bridge and enable wireless android auto on non-wireless android auto units.

Right now there are plenty of cars with android auto, but very few supports wireless android auto. From what i have heard, not even the new HMI units for the 2020 forward astra's have wireless android auto, which is quite a shame...Especially since those cars have wireless charging.

Would be awesome to be able to have the phone in the pocket, and have AA, connect automatically via wireless, and if you needed to charge the phone, just pop it into the hole in the centre console, that has wireless charging.

No more fiddeling with cables, and no more connectors in the phone and on the cable, going bad, because you accidentally bent the connector, while it was inserted into the phone.

Google would be the perfect to do this dongle as they know the most about the AA and AA wireless protocols.
