How to Switch SiriusXM to Another Car (Radio ID + Steps)

To switch SiriusXM to another car, you either move your service from the old vehicle to the new one or link the new vehicle to your existing account, and you need the new radio’s Radio ID (also called the ESN) to do it. Trial subscriptions are the exception, because SiriusXM’s help center says a trial cannot be transferred. This guide covers the Radio ID, each situation (new car, used car, sold car, portable radio), the contact options SiriusXM lists, and what to avoid.

Facts below come from SiriusXM’s own help pages, read on 2026-10-14. Phone numbers, steps and fees change, so confirm in your account before you act.

Switching Your SiriusXM Service to a New Vehicle

SiriusXM’s transfer page describes two options: remove your old vehicle and transfer service to the new one, or link the new vehicle to your existing subscription. It says all you need is the Radio ID, ESN or VIN of the new vehicle, and that transfers and linking are handled by phone, chat or through your online login.

If you are moving a portable radio instead, the receiver travels with you but still needs an antenna cable that reaches. The pick below is a 3 foot extension for plug-and-play receivers.

Which Situation Are You In?

This table pairs each case with what SiriusXM’s pages say to do. It summarizes those pages and is not a guarantee for your account.

Situation	What to do	Where, per SiriusXM
Same portable or dock-and-play radio moving to another car	Keep the radio, move it to the new car and confirm it receives a signal	The “more than one vehicle” page says these radios can move between cars and home
Factory radio in a new car, old car sold or traded	Remove the old vehicle and transfer service, or link the new vehicle to your plan	Transfer page: phone, chat or online login; Radio ID, ESN or VIN of the new car
Factory radio in a new car, old car kept	Add the new car as another radio on the same account	“Add Car + Streaming” in the Online Account Center, then enter the Radio ID
Used car that may have an active trial	Send an activation signal; if that fails, start a new trial	“Activate Trial in Vehicle” help page
Lifetime subscription	Call or chat with a Listener Care agent	Transfer page says only phone or chat
Trial subscription	Do not expect it to move; add a follow-up plan to the new radio instead	Help center article on trial transfers; add-vehicle page

If you want SiriusXM in two cars at once instead of moving it, see our guide on having SiriusXM in 2 cars.

Understanding Your SiriusXM Radio ID

Every transfer or add-a-vehicle request starts with the Radio ID, so find it before you call or log in. SiriusXM’s Radio ID page says that for most radios the ID displays when you tune to channel 0. The page also calls it an ESN or RID. If channel 0 does not show it, the page says SiriusXM can help you find it through the help center.

The same page lists maker-specific routes for radios that do not use channel 0. These are examples from that page, not a full list, so check it for your model year.

• Ford and Lincoln SYNC 3 (select MY20): tune to channel 0, then Apps, Sirius Travel Link, Subscription.
• BMW: in Sirius mode, hold the SAT button for more than 3 seconds (listed for 2003 to present).
• Mercedes-Benz: Audio, SatRadio, Service.
• Mazda Connect (2014 or later): select XM as the source, then channel 0 from the channel list.
• Mitsubishi: press SAT.

Length differs by radio: the page states a 12-digit ID for pre-2014 Mazda models and an 8-digit ID for Mazda Connect models, so copy the ID exactly as shown. If it is not on the screen, your owner’s manual or the maker is the next stop.

How to Contact SiriusXM for a Transfer

SiriusXM’s contact page lists online chat, offered 24/7, and phone support with call center hours of Mon to Sun, 8 am to 8 pm ET. It asks callers to have the account number or Radio ID (ESN or RID) ready. The phone number itself did not display on that page when it was read for this guide.

Different official pages list different numbers, so each is reported as written, and which is current for your case cannot be confirmed here:

SiriusXM page	Number it lists	What the page says it is for
New Car Transfer Service	855-227-6738	Transfers; hours shown Mon to Fri 8 am to 10 pm ET, weekends 8 am to 8 pm ET
Trial benefits page	(866) 635-2489	Transfers and adding a vehicle
Lucid vehicles FAQ	1-855-596-9555	Buying by phone and Listener Care support

Open SiriusXM’s own site yourself and use the number or chat shown there. The old shortcut address siriusxm.com/turnkeytransfer, which still draws search traffic, redirected to a SiriusXM account login page when checked, but that login page would not load, so what it offers today is not described here.

Moving Your Subscription When Buying a New Car

With a factory radio in a new car, the radio is new to SiriusXM, so the move is an account change, not a hardware change. SiriusXM’s trial page says you can transfer service or link your new vehicle to your existing plan, and that it will pause your billing through the end of your trial. It also says you will not lose any of your trial subscription when you transfer service, and that the length of a trial depends on the vehicle you bought or leased.

A separate help center article answers whether a trial can be moved to another vehicle with a flat no. The pages do not reconcile the two, so ask an agent which applies to you before you cancel anything.

If you are keeping the old car, the add-a-vehicle route is the one to use. SiriusXM’s page says to sign in to the Online Account Center, select “Add Car + Streaming” on your dashboard, enter the new vehicle’s Radio ID and follow the prompts. Its “more than one vehicle” page adds that this may qualify you for the Family Discount, though it lists no amounts. Lifetime subscriptions are the special case: the transfer page says they can only be transferred by phone or by chatting with a Listener Care agent.

Buying a Used Car With SiriusXM Already in It

A used car adds a question the other cases do not have: what is already on that radio. SiriusXM’s “Activate Trial in Vehicle” page covers pre-owned and certified pre-owned cars. If the dealer told you a complimentary trial came with the car, the page says the trial should be active at the time of purchase. If you received no trial information and the satellite radio is not working, it says to try sending a signal first and, if that fails, to start a new trial through its pre-owned trial page.

The signal steps on that page are specific. Power on the radio and tune it to channel 184 for Sirius radios or channel 1 for XM and SiriusXM radios, make sure the antenna has a clear view of the sky, and then tune to channel 4 to check. The page says that if you hear audio, no further steps are required. A Radio ID is required to send the signal.

What the pages read for this guide do not say is how a previous owner’s paid plan is handled once the car changes hands. Do not assume it carries over to you or that you can use it. Treat the Radio ID as the starting point, and ask SiriusXM what is on that radio before you pay for anything.

What If You Sold Your Old Vehicle

When the old car is gone, the cleanest result is that SiriusXM no longer lists it on your account. The transfer page’s wording is to remove your old vehicle and transfer service to your new one. The trial page tells you to remove any old radios you no longer have, and SiriusXM’s Lucid vehicles FAQ gives a self-serve path: log in to My Account, select Manage for the vehicle whose service you want to move, then choose Transfer subscription from the Modify dropdown and follow the prompts.

Do this before you hand over the keys if you can, while the old Radio ID is still easy to read. If you use the SiriusXM app in the car, our guide on connecting the SiriusXM app to your car covers that separate setup.

Moving a Portable or Aftermarket Radio Between Cars

A portable or dock-and-play radio is the easiest case for the account, because the Radio ID travels with the radio. SiriusXM’s “more than one vehicle” page lists dock-and-play radios as units that move between cars and home. For a radio you already own, it says to register an account if you are new, open the Subscriptions tab, click Find subscription, enter your Radio ID and follow the prompts.

The hardware side is where moves go wrong. SiriusXM’s help center says a Sirius- or XM-Ready vehicle was equipped at the factory with a radio capable of receiving SiriusXM, but that you may still need an antenna or tuner and should speak with your dealer. For a receiver you are moving yourself, check that the new car has a compatible antenna connection before you plan the day around it. If the cable will not reach, the extension cable in the box above is one option, with the listing’s own limit: it is described as working with plug-and-play receivers and SXV tuners, and not with boomboxes or powered speaker systems.

For help picking a place to mount the receiver and route the cable, our guide on how to use a Sirius radio in a car covers the everyday setup.

Fees: What SiriusXM’s Pages Actually State

Older versions of this article said the transfer is normally free. That claim is removed, because none of the SiriusXM pages read for this guide (transfer, add-a-vehicle, trial) states a transfer fee. Other websites quote dollar amounts, but none could be confirmed on a SiriusXM page, so they are not repeated here. Ask the agent for the exact cost and any plan change before you approve it.

Topic	What SiriusXM pages say	What is not stated
Transfer fee	No amount listed on the transfer, add-vehicle or trial pages	Whether any fee applies to your plan
Family Discount	May apply when you keep the old car and add the new radio	The discount amount
Trial during a transfer	Billing is paused through the end of the trial; trial is not lost	How it interacts with the “trials cannot be transferred” article

Troubleshooting After the Switch

If the radio shows no audio after the account change, work through the pages’ own steps in order. First, confirm the antenna has a clear view of the sky. SiriusXM’s lost-signal page then gives a power cycle: turn off the vehicle, including the radio, open and close the driver side door, and wait 3 minutes before turning the vehicle and radio back on. Next, send a signal request with the radio on and tuned to the preview channel (184 or 1, as above). If the signal still does not return, that page says to contact your dealership support line and ask for the radio reset process specific to your vehicle, ways to check the antenna, and any other vehicle-specific steps.

Checklist Before You Call or Log In

1. Write down the new radio’s Radio ID (channel 0 on most radios), or the VIN of the new car.
2. Have your SiriusXM account number or the old radio’s Radio ID ready, since the contact page asks callers for the account number or Radio ID.
3. Decide which route you want: transfer and remove the old vehicle, or link the new one and keep both.
4. Check whether any of the plan is a trial or a Lifetime subscription, because those follow different rules.
5. Ask for the exact cost, effective date and any change to your plan, and write down the confirmation.
6. Test the radio on the preview channel with a clear view of the sky before you leave the driveway.

What to Avoid: Third-Party Transfer Services and Scams

The FTC’s imposter scam guidance advises not to send money to someone you do not know who contacts you unexpectedly, not to click links or call numbers in unexpected messages, and to contact the organization using details you already know are real. Apply that here: do not pay a website or caller that offers to “transfer” your radio for a fee unless you reached it from SiriusXM’s own site, and do not give a stranger your account login. Report scams at ReportFraud.ftc.gov.

SiriusXM’s own transfer details are on its New Car Transfer Service page, which is the page quoted throughout this guide.
