How to install an app on an Android head unit
The MK4 runs Android 13 with the Google Play Store on it, so you install apps the same way you would on a phone. Sign in to a Google account first. Almost every "Play Store will not work" report comes back to that step or to old software.
What this gives you
Navigation, music, offline maps, touring apps, diagnostics and messaging all run on the unit itself rather than being mirrored from a phone. That is the difference between a screen that shows your phone and a screen that is its own computer.
Before you start
- A Wi-Fi connection, a phone hotspot, or a SIM in the unit. The Play Store needs internet.
- A Google account. Any existing one works.
- The current software on the unit. An out of date build is the most common reason sign-in fails.
Step by step
- Get the unit online
Go to Settings, then WiFi, and join your home network, a phone hotspot or a Starlink connection. If you are using a SIM, insert it into the card slot and make sure the 4G antennas are connected.
- Set the time zone, the date and the time
A wrong clock blocks a Google sign-in, and the error it gives you does not say so. Set these before you try to sign in, not after it fails.
- Open the Play Store and update it before signing in
Open the Play Store, press the three dots for the menu, and select Update. Updating the Play Store first prevents most login and app problems.
- Sign in to your Google account
Follow the prompts. If you have just done a factory reset and get "Something went wrong", it is almost always the clock again. Set the time, then power the unit off for ten seconds so the time sticks, and try again.
- Search for the app and install it
Search by name, tap Install, and it appears in the apps grid. Open the apps grid with the four square icon.
- Update your apps from time to time
Google system and service updates are what keep the unit stable, so it is worth opening the Play Store now and then and letting the updates run.
If it does not work
If the Play Store will not sign in at all, or the unit keeps rebooting, install the latest software update for your unit and try again. That fixes it in almost every case, and it is a free fix rather than a fault.
Worth knowing
Netflix is worth one caveat: it may restrict playback on uncertified Android devices, which is a decision Netflix makes and not something the unit controls.
