- MK4 steering setup, factory LC70 path vs PVS wheel kits / receivers (how-to before “it’s broken”).
- Buttons dead after you thought setup was done → MK4 steering not responding. Other cars + SWC modules → SWC pairing · Steering hub.
Quick answer
Factory LC70 wheel audio keys use the OEM Android steering-learn path; PVS aftermarket wheel kits need the bundled wireless receiver and its learn sheet - a bare MK4 does not ship that receiver, so match your wheel type before chasing settings.
Problem
- Steering buttons should control the MK4; you need the correct setup path.
Symptoms
- Steering buttons dead, wrong, or unclear which setup path applies.
Cause
- Factory LC70 wheel path differs from aftermarket wheel + adapter chains.
- The PVS wireless SWC receiver ships with PVS wheel kits - not with a bare MK4 on its own.
Fix Step-by-step
- Factory Toyota buttons: use factory path - no separate PVS wireless receiver.
- Bezel keys still do volume / home / media.
- Third-party wheels: use supported adapters; PVS cannot guarantee all brands.
- Re-run steering learning in Android settings if offered.
- PVS wheel kits: follow receiver learn + button pairing sheet.
Notes
- Dead buttons: Not responding (troubleshoot)
- Vol/phone audio odd: Bluetooth no audio, Phone pairing
- Harness: Wiring
- First boot: Setup
- General SWC: Steering wheels hub

- Wheel + kit: factory Toyota audio keys vs PVS wheel kit vs third-party wheel (state which).
- Vehicle: model, series, and year.
- Photos: SWC harness plugged at the MK4; PVS wireless receiver (if fitted) plus LED/blink state during learn if the sheet references it.
