The easiest way to add an infotainment system to a vehicle that lacks it usually comes with a car radio.

The idea is that you anchor the old telephone to the dashboard of the car in a safe way, a support for the air outlet also works for you: choose the fixing that you prefer; always with the precaution that it does not hinder your visibility at the wheel. Ideally, the old mobile should remain connected to the USB/car cigarette lighter so that it receives electricity while it is running (especially if its battery no longer lasts long).

Once you have the mobile looking in the car holder, and it is connected, It’s time to transform that old Android into a complete Android Auto. For practical purposes it will be exactly the same as having the vehicle operating system in your own car. And you only need one application: Headunit Reloaded. There is a trial version to check that it works on your old phone (it lasts 10 minutes) and the paid version for 4.89 euros.
