U0496: Invalid Data Received From Subscription Entertainment Receiver Module
What to do
Check whether the subscription is actually paid before anyone charges you to look at this.
This is the satellite or subscription radio receiver. A subscription that has lapsed is not a fault — the equipment works, the signal arrives, and the service declines to authorise it. The screen usually shows an unhelpful error rather than saying so plainly, and a lot of money gets spent diagnosing an unpaid bill.
If you bought the car second-hand, this is especially likely. The subscription belonged to the previous owner and almost certainly was never transferred.
If the car was imported, that is the other common answer. These services only broadcast in certain countries, and a receiver for one that does not cover where you live cannot be repaired into working.
If it is genuinely a technical fault, it is usually the aerial rather than the receiver. Satellite reception needs a clear view of the sky, so mention anything to do with the roof — headlining work, a roof box or bars, or a leak. If the satellite navigation has also been struggling, that points at the roof aerial and makes it one fault rather than two.
Nothing about this affects driving the car.
What this code means
The subscription entertainment receiver is broadcasting data that cannot be accepted as true. See U0400 for the family's framing.
This is the satellite or subscription radio receiver, and the first thing to establish about it is not electrical: is the subscription current?
A lapsed subscription is not a fault. The receiver is working, the signal is arriving, and the service is refusing to authorise it — which is exactly what it is designed to do. The head unit generally shows an unhelpful error rather than saying so, and a great deal of time gets spent diagnosing a bill somebody stopped paying. Vehicles sold second-hand carry these codes for years for that reason, since the subscription belonged to the original owner and was never transferred.
The second thing is geography. These services are regional. An imported vehicle carries a receiver for a service that does not broadcast where the vehicle now lives, and no repair changes that.
Where the fault is genuinely technical, it is usually the aerial rather than the receiver. Satellite reception needs a clear view of the sky, so it is affected by exactly the things at U0486 — the roof antenna module and its connectors, headlining work, a roof box, and water at the roof seal. A receiver reporting an implausible signal state alongside poor satellite navigation performance is one fault at the roof rather than two in the entertainment system.
Nothing here affects the vehicle's operation.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
