How to Connect SiriusXM to Your Car: App, Bluetooth & CarPlay
“SiriusXM in my car” can mean two different things: the app on your phone playing through the car’s speakers, or the satellite radio built into the dashboard and linked to your account. This guide starts with the app, because that is the version that needs a connection method: Bluetooth, a USB or aux cable, Apple CarPlay or Android Auto. It then covers how to link a built-in radio, and it corrects one common claim about Android Auto that is out of date.
Quick Answer
Install the SiriusXM app, sign in, then connect the phone to the car with CarPlay, Android Auto, Bluetooth, USB or an aux cable. A streaming-only plan works in the car. The app uses your phone’s data, not the satellite antenna. To link a built-in radio instead, tune to channel 0 to read the Radio ID and add it to your account.

Getting the SiriusXM app into your car takes five steps whatever the connection. Only step 3 changes from car to car.
- Install the SiriusXM app: Get it from the App Store (iPhone) or Google Play (Android).
- Sign in with a plan that includes streaming: Use your existing login, or start a trial or a streaming-only plan at siriusxm.com.
- Pick the connection your car supports: CarPlay, Android Auto, Bluetooth audio, or a USB or aux cable. The table below matches each to what you can see on the dashboard.
- Connect the phone to the car: Do the first-time setup while parked.
- Open SiriusXM and play a channel: If you hear it through the car speakers, you are done. If not, set the stereo source to match the connection (Bluetooth, USB or AUX).
App or Built-In Radio: What Changes in the Car
Most confusion comes from mixing up the two. The table below uses facts from SiriusXM’s own help pages, as of October 2026. Plans, prices and app versions change, so check siriusxm.com before you buy.
| SiriusXM app (phone) | Built-in satellite radio | |
|---|---|---|
| How it plays | Streams over your phone’s mobile data or Wi-Fi | Receives the satellite signal through the car’s antenna |
| Works with CarPlay or Android Auto | Yes. They stream from the phone and are not connected to the vehicle’s satellite radio | Not applicable |
| Needs | A qualifying plan, and a data connection away from Wi-Fi | A radio that is active on your account (Radio ID) |
| Free Access (ad-supported) | Not available in the app, per SiriusXM | Available only through the vehicle’s radio |
| Favorites | Do not sync with the satellite radio | Do not sync with the app, web player, CarPlay or Android Auto |
Which Connection Fits Your Car?
| What your dashboard has | Best connection | Notes |
|---|---|---|
| A touchscreen with CarPlay or Android Auto | CarPlay or Android Auto | Cleanest option: SiriusXM appears on the car screen |
| Bluetooth audio (a Phone or BT source) | Bluetooth pairing | Wireless, but the phone still runs the app |
| A USB port | USB cable | Some ports only charge, so test before you rely on it |
| A 3.5 mm AUX jack | AUX cable or a Bluetooth AUX receiver | Set the stereo source to AUX |
| Only an FM radio or a cassette deck | Bluetooth FM transmitter or cassette adapter | Sound quality is lower than a direct connection |
Connecting Your Mobile Device To Your Car Stereo
SiriusXM lists four ways to listen in a car with the app: CarPlay, Android Auto, Bluetooth audio, or an aux or USB cable. If your car has CarPlay or Android Auto, jump to the next section. The two methods below work with the app on any phone.
Using Bluetooth (Recommended for Most Cars)
SiriusXM’s pages do not give brand-by-brand pairing steps, so use your owner’s manual for the exact button names. The usual flow looks like this:
- Turn Bluetooth on in your phone’s settings.
- Put the car stereo into pairing mode from its Phone or Bluetooth menu.
- Choose the car’s name on the phone and confirm any code that both screens show.
- Switch the stereo source to Bluetooth audio.
- Open the SiriusXM app and play a channel. If sound comes from the car speakers, the connection works.
If the phone will not pair at all, our guide on how to sync your phone to your car covers the pairing fixes. If the audio is the problem, check the phone’s data signal first, because the app is streaming.
Using a USB or Auxiliary Cable
A cable needs no pairing. For aux, plug a 3.5 mm cable from the phone (or a headphone adapter) into the car’s aux-in and set the stereo to AUX. For USB, plug into the car’s USB port and select the USB source if the stereo supports audio over USB; some ports are for charging only. If the car has an aux port but no Bluetooth, a Bluetooth AUX receiver like the one in the box above avoids the cable entirely.
Integration With Car Systems
CarPlay and Android Auto both play SiriusXM from your phone. SiriusXM states that neither is connected to the vehicle’s satellite radio, so a data connection is required even if the car has a satellite radio and an active account.
How to Use SiriusXM with Apple CarPlay
- Install the SiriusXM app on the iPhone and sign in.
- Connect to a CarPlay radio. Some radios need a USB cable; others support wireless CarPlay. For wireless, Apple’s steps are to put the car in wireless or Bluetooth mode, make sure Wi-Fi and Bluetooth are on, then choose the car under Settings, General, CarPlay.
- Choose SiriusXM from the CarPlay dashboard.
Per SiriusXM, a trial or paid subscription to Platinum, Music & Entertainment, Streaming Platinum, Streaming Music & Entertainment, Streaming Music Showcase or All Access (App Only) gives you CarPlay access. If SiriusXM is missing, Apple suggests trying another USB cable and port, confirming Siri is on, and checking Settings, Screen Time, Content & Privacy Restrictions, Allowed Apps. As a last step, tap your car under Settings, General, CarPlay, choose Forget This Car and set it up again.
How to Use SiriusXM with Android Auto
- Install the SiriusXM app from Google Play and sign in on the phone.
- Connect the phone to the car. Google’s instructions: park with the infotainment system on, then use a USB cable, or for wireless pair over Bluetooth the first time with Bluetooth, Wi-Fi and Location on.
- Select SiriusXM in the Android Auto media list.
Myth check: Android Auto does not require a satellite radio plan. Older advice, including an earlier version of this page, said a streaming-only plan would not work. SiriusXM’s own help center says a trial or paid plan that includes streaming, such as All Access (App Only), is what Android Auto needs, and its Ways to Listen page lists Android Auto as a way to use a streaming-only plan. A satellite-only plan with no streaming is the one that falls short. App and Android version requirements change, so check the SiriusXM Android Auto help page for the current minimums.
How to Add Your Vehicle to Your SiriusXM Account
This section is for a built-in satellite radio, not the app. Many searches for siriusxm.com/linkmyvehicle come from people who just bought a car with a trial. Linking uses the radio’s ID, not your phone.
- Find the Radio ID: With the car on, tune the radio to channel 0. On most radios it displays the Radio ID (also called ESN or RID). If it does not, check the radio menu or owner’s manual. SiriusXM lists manufacturer steps: on a BMW, hold the SAT button for more than three seconds; on Ford and Lincoln Sync 3, go to Apps, Sirius Travel Link, Subscription.
- Look the radio up: The SiriusXM account center accepts a Radio ID, VIN or license plate. If the radio already carries a subscription, the lookup asks you to sign in to manage it.
- Add or transfer service: Sign in to your account, add the new vehicle, and remove or transfer an old radio if you are replacing a car.
- Send a refresh signal if it stays silent: SiriusXM says the radio may need up to 15 minutes to receive the signal. Keep it tuned to a satellite channel with a clear view of the sky, not inside a garage or under heavy trees.
Use the contact options on siriusxm.com if the radio still has no channels after that. The dealer can help if the radio shows no satellite signal at all.
Troubleshooting Common Connection Issues
Set up and test while the car is parked. Google’s Android Auto instructions say the same, and a phone is not something to fiddle with while driving.
| Symptom | Most likely cause | Fix to try |
|---|---|---|
| Silence, but the phone shows SiriusXM playing | Stereo is on the wrong source | Switch the source to Bluetooth, USB or AUX to match the connection |
| Buffering or dropouts | Weak mobile data, since the app streams | Check signal, switch airplane mode on and off, or reopen the app |
| Bluetooth connected but no audio | Stale or incomplete pairing | Forget the car on the phone, delete the phone on the stereo, pair again |
| No SiriusXM on CarPlay | Cable, Siri off or Screen Time restriction | Follow Apple’s steps above, then Forget This Car and set up again |
| No SiriusXM on Android Auto | App signed out or glitch | Quit the SiriusXM app, reopen it, reconnect to Android Auto |
| Built-in radio shows no channels | Radio not linked or not refreshed | Confirm the Radio ID on your account, then send a refresh signal |
Frequently Asked Questions
Do I need a satellite radio in my car to use the SiriusXM app?
No. SiriusXM says you can listen in a car without a SiriusXM-equipped radio by using a streaming-only plan through CarPlay or Android Auto, an aux or USB cable, or Bluetooth audio. The phone supplies the connection, so you need a cellular data plan whenever you are not on Wi-Fi.
Does the SiriusXM app use my phone data in the car?
Yes. The app, CarPlay and Android Auto all stream SiriusXM from your phone, not from the satellite antenna, so they use mobile data or another internet connection. The SiriusXM pages checked for this guide do not give one fixed per-hour figure, so watch your carrier’s usage screen for the first few drives.
Why is SiriusXM not showing on CarPlay or Android Auto?
Start with the basics: sign in to the SiriusXM app on the phone first, confirm your plan is one that works with CarPlay or Android Auto, and reconnect. On an iPhone, also check Settings, Screen Time, Content and Privacy Restrictions, Allowed Apps and make sure CarPlay is allowed. On Android, SiriusXM suggests quitting the app, reopening it and connecting to Android Auto again.
Can I use the SiriusXM app and my car’s built-in radio together?
They are two separate ways to listen. CarPlay and Android Auto are not connected to the vehicle’s satellite radio, and favorites you change on the radio do not sync to the app, the web player, CarPlay or Android Auto. Whether one plan covers both a radio and the app depends on the plan you hold, so check your account before you pay twice. For two cars on one account, see our guide to having SiriusXM in 2 cars.
How do I use SiriusXM if my car does not have Bluetooth or CarPlay?
If the stereo has a 3.5 mm aux jack, run a cable from the phone or use a Bluetooth AUX receiver. If it has neither Bluetooth nor an aux jack, the common fallbacks are a cassette adapter or a Bluetooth FM transmitter that plays the audio on an open FM frequency.
Conclusion
To connect the SiriusXM app to a car, match the connection to the dashboard: CarPlay or Android Auto if the screen has them, Bluetooth or a cable if not, and an adapter for older stereos. Remember that the app streams over your data and is separate from the built-in satellite radio. For the radio, tune to channel 0, link the Radio ID to your account and allow time for the refresh signal.
