If you have an old tablet sitting in a drawer, barely used, you can give it a new lease of life by turning it into an Android Auto display in your car. This Google system lets you use GPS, manage calls, control music, and even receive messages without having to touch your phone while driving.
Instead of spending money on a dedicated vehicle display, reusing an old tablet is a cost-effective and practical solution. In this article, we'll show you step-by-step how to do it with the help of an app that turns your tablet into a fully functional Android Auto.
Why use a tablet as an Android Auto display?
Android Auto is a very useful platform for driving, as it integrates popular apps like Google Maps, Spotify , and WhatsApp into its interface . However, not all cars have a screen compatible with this system, forcing drivers to use phone mounts or invest in additional devices.
Reusing a tablet offers several advantages:
- Larger screen size: Unlike a mobile phone, a tablet allows for better viewing of maps and controls.
- Zero investment in hardware: If you already have an unused tablet, you can take advantage of it without having to purchase additional equipment.
- More immersive experience: The large, touch-enabled interface improves navigation and makes using Android Auto easier.

- Enough power: While you don't need the latest hardware, a decent processor will ensure a smooth experience.
- Car Holder: Purchase a suitable mount to secure your tablet to your dashboard without compromising visibility.
- Car charger: Keeping your tablet charged while driving is essential for extended use.
