Installation Recommendations
- Disconnect Battery Before Work: Always disconnect the vehicle battery before removing interior trim or electrical modules to avoid short circuits and protect vehicle electronics.
- Access Location: The module is typically mounted behind the radio, inside the glovebox or in the center console depending on model and equipment level. Remove surrounding trim panels and the head unit to reach the connector block.
- Connector Handling: Release locking tabs gently and avoid pulling on wires. Inspect connector pins for corrosion or damage before fitting the replacement.
- Configuration And Pairing: After physical installation, pair phones and USB devices. In some vehicle configurations the module may require software initialization or adaptation with PSA diagnostic tools (DiagBox) to restore full telephone and multimedia functionality—perform by a qualified technician if needed.
- Reassembly: Refit trims carefully and check that no wiring is pinched. Reconnect the battery and verify that Bluetooth, phone, and USB functions operate normally.
