Voice Search in the Car: CarPlay, Android Auto and Your Business

A family is southbound on I-35 outside New Braunfels. The kids are hungry and the mood is turning. The driver presses the steering-wheel button and says, "Hey Siri, find tacos near me." Siri reads one name and a distance, and asks whether to get directions. The driver says yes. Nobody in that car will ever know what the second-best taco shop was.

Car requests are the bluntest kind of voice search. The person asking is busy, moving, and not in the mood for a conversation. They come in a handful of shapes, and each shape leans on a different part of your listing.

Notice how little of this involves persuasion. A driver doesn't hear your slogan. The car is not going to describe your warm and welcoming lobby. In the car, marketing is a set of fields filled in correctly, and the business with the fewest wrong fields gets the visit.

CarPlay is the iPhone, projected onto the dashboard. When a driver asks Siri for a business, the answer comes from Apple Maps, which you manage through Apple Business Connect. Some drivers run Google Maps or Waze inside CarPlay and search there instead, but Siri's own spoken answer starts with Apple. The full Apple side is in the guide to getting your business on Siri.

Android Auto is the Android phone, projected the same way. Its assistant has been Google Assistant, and Google has been moving it to Gemini on a schedule that depends on the phone, the region and the car. Either way, a local answer comes from Google Maps and your Google Business Profile. The Google Assistant and Gemini guide covers that profile in depth.

A growing number of cars also ship with an assistant of their own. Some have Google built in, which reads Google's data. Some have Alexa built in, which means the same Yelp and Bing sources described in how Alexa finds local businesses. A few carmakers run their own voice systems on top of a licensed map. You can't control which one your customer bought. You can make sure each source tells the same story.

At a desk, a customer who sees questionable hours might call to check. In a car, they won't. "Open now" is built into many driving requests, said aloud or not, and an assistant that believes you are closed will simply skip you. It will not mention you were close. It will not apologize.

Hours go wrong in boring ways. The holiday nobody updated. The new Saturday schedule that made it onto the door but not onto Apple Maps. The "temporarily closed" flag somebody switched on during a remodel and forgot. The second location that inherited the first location's hours. Every one of these sends drivers somewhere else, quietly, for as long as it stays wrong.

The phone matters for the same reason. A driver who says "call them" is not going to redial a dead number, look up another, or leave a voicemail on a full mailbox. The assistant dials once. Whoever picks up has the customer.

Every map turns your street address into a single point. Apple and Google do this separately, with their own data, and they don't always land on the same spot. Most of the time the difference doesn't matter. At certain kinds of properties it decides whether the customer finds you or gives up.

The trouble spots are predictable. A suite in a strip center, where the pin lands in the middle of the parking lot or on the anchor tenant. A corner lot whose address is on one street and whose driveway is on the other. A medical building with four entrances and a parking garage. An office park where every building shares one street number. A rural route, or new construction the maps haven't caught up with. A shop whose customer entrance is around back, behind the loading dock.

In each case the driver follows the pin, arrives at the wrong place, and has to figure out the rest while traffic waits behind them. Some will call. Some will circle. Some will see the competitor's sign across the road and take the hint.

Owners like to draw a circle on a map: we serve everyone within ten miles. Drivers don't think in circles. They think in minutes, exits and left turns. A tire shop three miles away across a highway with no nearby exit is, to a driver, farther than one five miles away on the same road.

Neither Apple nor Google publishes exactly how distance is weighed for a moving car, and both have reasons not to. What is clear from ordinary use is that the answer depends on where the car is, which way it is heading, and what roads connect the two points. "On my route" searches make that explicit. Plain "near me" searches from a car seem to behave much the same way.

That means your real competitive area is lumpy. It bulges along the roads that lead to you and pinches at rivers, rail lines, toll roads and stretches with no turnaround. Rush hour can shrink it. A new interchange can grow it overnight.

You can't move the highway. You can make sure that inside your drive-time shape nothing about your listing gives the assistant a reason to pass you over. If you serve customers at their homes rather than at a shop, the logic is different again, and the near-me guide covers how service-area businesses are placed. For the screen version of the same contest, the Google Maps guide explains the three-pack.

The point is to hear what a customer hears, from where they are. A test from your desk tells you what the assistant thinks of your desk.

Pick the three or four roads that actually bring you business: the highway exit, the commuter route, the road past the big-box store everyone visits on Saturday. Have someone drive them while you ask from the passenger seat, once with an iPhone in CarPlay and once with an Android phone in Android Auto if you can borrow one. Ask in the customer's words, not yours. Then, still parked at the end, say "navigate to" followed by your exact business name and see where the route ends.

Do one run early in the morning and one shortly after you close. Open-now filters show their teeth at the edges of the day. If a competitor wins on one road and you win on another, that is useful too. It tells you where your drive-time shape actually ends.

In order: hours, phone, pin, parking and entrance, then everything else. Hours and phone decide whether you are named at all. The pin decides whether a named customer arrives. Parking and entrance details decide whether they arrive in a good mood.

The free Voice Search Visibility Check shows what Google, Apple Maps, Yelp and your website currently say about your hours, phone and address, which is most of what a car will read. For the map side specifically, the Map Pack Audit looks at how you place on Google Maps. If the Apple and Google records disagree with each other, our write-up on the Google setting that decides whether Siri recommends you is worth five minutes.

If you would rather hand it off, voice and ambient assistant optimization includes pin checks on both maps, profile cleanup across Apple, Google, Bing and Yelp, and spoken tests from the roads your customers use. The voice search guide shows how the car fits with the kitchen speaker and the phone.
