How to open your Volkswagen Beetle Cabrio garage door without Homelink?

There is an alternative way to open your garage door from your Volkswagen Beetle Cabrio without using Homelink, called Android Auto. Your Volkswagen Beetle Cabrio is certified by Google to use Android Auto.

 Android Auto is a piece of software that allows your android phone to interface with your  Volkswagen Beetle Cabrio ’s built-in entertainment and information system. Android Auto increases convenience and reduces distraction by putting commonly used apps, that would be necessary or especially useful while driving on your car’s infotainment display. By doing so, Android Auto minimizes the need to actually handle your android phone while driving.
Also you will need to buy and install an ismartgate device, a small hardware add-on. The ismartgate needs to be wired to the control board of your existing garage opener and connects to your ismartgate app via Wi-Fi.
