Android Auto is brilliant, right up until you need to do something, flying down the interstate at 60 mph, where Assistant refuses to behave, and taking your eyes off the road even for a second turns your vehicle into a homing weapon of great destruction. Google’s default settings for Android Auto are essentially a one-size-fits-all compromise. But anyone who spends more than thirty minutes a day commuting knows that repeated interaction with your infotainment system need not be so frustrating.

Thankfully, the settings are still permissive if you know where to look and what to change, so the Android OS prioritizes your ease of use. It beats switching to CarPlay, replacing the vehicle with one that packs Android Automotive, or even swapping out the head unit. A few hidden developer toggles, some basic automation, and a little common sense can strip out the daily annoyances. Here are the four exact tweaks I rely on.

Precise day/night mode control

When will Google fix this?

Android typically nails switching to dark mode when the sun goes down, but Android Auto, including the app drawer and various music players, often stays blindingly white long after dusk. This happens because Android Auto relies on the device's OS telling it when to switch. This implementation has been reported broken for years on end, but on the bright side (pun intended), you can trigger dark mode based on your vehicle's lights instead.

This system relies on a physical ambient light sensor or the headlight toggle to trigger the UI theme by default. If your vehicle doesn't have automatic headlights, the software will flip the switch when you manually turn the lights on. Google used to have an Android Auto Developer setting to have this behavior Vehicle Controlled or Phone Controlled, but the toggle was removed with AA15. Now, the Day/Night mode option for Maps in the basic AA settings relies on thevehicle headlight state when set to Automatic switching.

Using this is better than getting flash-banged by Maps on a nightly highway run in the rain, but hopefully Google fixes device-level switching controls so that when the OS goes into dark mode, your car infotainment UI changes too. For now, note that maxed-out in-car screen brightness settings may also override dark mode, regardless of the headlights' state.

Eliminating the double ringtone

And the instant state of panic that follows

When a call comes in, the car's speakers ring loudly, while my phone violently vibrates against the hard plastic of its receptacle, and I find that infuriating. It typically happens with WhatsApp voice calls that aren't automatically detected in Android Auto. Another related issue affects me when I'm on a WhatsApp call as I pull out of my driveway. The phone's standard Wi-Fi radio desperately clings to my home router’s dying signal rather than switching to mobile data, while Wi-Fi Direct maintains a steady connection with the Android Auto head unit.

I killed both these birds with one stone using programmable automations via Tasker or MacroDroid. I created a simple macro with a Bluetooth connection to the Android Auto head unit as the trigger, mapped to two actions. First, set the phone to silent with vibration disabled. Second, turn off Wi-Fi. I also added an exit trigger to reverse these settings when I disconnect from the head unit.

App drawer without the clutter

Especially with sideloading support

By default, Google clutters your dashboard with every single compatible app installed on your phone. GameSnacks, Angry Birds, something you opened last in 2022, it's all dumped onto your head unit without a second thought. Despite the limited selection of Android Auto-compatible apps, this clutter quickly becomes a massive headache. I realized this when I needed to pull up Waze instead of Google Maps while doing highway speeds and tolerating Assistant's incompetence. It's plain dangerous.

Open the Android Auto settings on your phone and tap Customize launcher to fix this. Be ruthless and uncheck the garbage you never use in the car. Once you've purged the bloat, drag and reorder the remaining apps based on frequency of use, or in a large vehicle, proximity to the driver. This way, you can launch your preferred media app with a quick glance from the corner of your eye without leaning out of your driving position.

Voice match in the car

For bulletproof recognition from Google Assistant

Circling back to Assistant's incompetence, it typically starts with the summon. If your Android device isn't responding predictably and promptly, you might need to retrain your voice model to improve success rates. Usually, the microphone in your car might struggle to detect "Hey Google" accurately if you're using an aftermarket head unit without a physical, dedicated steering wheel button for Assistant. It could be anything from low-quality mics and low-gain settings to your distance from the microphone in the car, causing the problem, even if on-device hot-word triggers work beautifully.

The solution lies in retraining Google Assistant Voice Match when you're seated in the car with Android Auto connected and the car's features, like the A/C and engine, running as they usually would. This forces Assistant to learn your voice profile layered directly over the specific acoustic background noise of your car's cabin. The improvement in trigger accuracy is immediate. The best part is that I've found it works well with Gemini for Android Auto, too.

Android Auto is yours to customize

I'll admit Android Auto isn't exemplary in the personalization department, but spending a few minutes dialing down these settings and setting up automations can smooth your transition from the device to your vehicle's infotainment system, and then back again.
