- MK4 steering setup, the factory LC70 path or a PVS wheel kit and receiver (how-to, before “it’s broken”).
- Buttons dead after you thought setup was done → MK4 steering not responding. Other cars and SWC modules → SWC pairing · Steering hub.
Quick answer
If you've got the factory LC70 wheel, your audio keys use the OEM Android steering-learn path. With a PVS aftermarket wheel kit you need the bundled wireless receiver and its learn sheet. A bare MK4 doesn't ship that receiver, so check which wheel you've got before you chase settings.
Problem
- Your steering buttons should control the MK4, and you need the right setup path.
Symptoms
- Your steering buttons do nothing, do the wrong thing, or you're not sure which setup path applies.
Cause
- If you're on the factory LC70 wheel, that's a different path to an aftermarket wheel and adapter chain.
- You get the PVS wireless SWC receiver with a PVS wheel kit, not with a bare MK4 on its own.
Fix Step-by-step
- Factory Toyota buttons: use the factory path. You don't get a separate PVS wireless receiver.
- Use the bezel keys for volume, home and media.
- Third-party wheels: use a supported adapter. We can't guarantee every brand.
- Re-run steering learning in Android settings if it's offered.
- PVS wheel kits: follow the receiver learn and button pairing sheet.
Notes
- Buttons dead: Not responding (troubleshoot)
- Volume or phone audio odd: Bluetooth no audio, Phone pairing
- Harness: Wiring
- First boot: Setup
- General SWC: Steering wheels hub

- Wheel and kit: factory Toyota audio keys, a PVS wheel kit or a third-party wheel (tell us which).
- Vehicle: model, series and year.
- Photos: the SWC harness plugged in at the MK4, the PVS wireless receiver if you've fitted one, plus the LED or blink state during learn if the sheet mentions it.
- Where you're stuck: which step number on the supplier sheet fails, and what you see on the MK4 screen at that moment.
