Android Auto does a lot to make your phone more useful and safe in the car---it simplifies the interface and limits functionality, only allowing access to key apps that you need while on the go. More recently, Google incorporated an "auto-reply" feature that allows users to quickly reply to incoming messages.

By default, this action is executed with a simple tap of a button, regardless of whether you're using Auto on the phone or a dedicated Auto head unit. It works with multiple messaging services, like SMS, Facebook Messenger, WhatsApp, Hangouts, and more.

The default reply is set to "I'm driving right now." But you're not a "default message" kind of person, are you? You like a little customization in your messages. I can appreciate that. Fortunately, there's a simple way to change it.

To make matters even nicer, you tweak this all from the Android Auto app, which means it doesn't matter if you use it as a standalone app or with a dedicated head unit.

First, fire up Auto. Tap the three lines in the upper right corner to access the menu.

From here, choose "Settings."

Under the Messaging section, the top option is "Auto Reply." This is where you'll change your custom response.

Type in the desired response, click "OK," and that's that.

Unfortunately, there's no way to set custom responses on a per-app basis. That means if you plan on using the Auto Reply feature, every app gets the same one. No one is special in Android Auto's world.

It's also worth mentioning that you can disable the popup notification that displays when you get a new message by un-toggling the "Show message notifications" option.

Bam. Love it.
