SW306 Bluetooth Handsfree + Audio Streaming

The CCF parameters behind Bluetooth Handsfree and Audio Streaming

The dropdown above maps to these values in the Car Configuration File:

The Bluetooth Handsfree and Audio Streaming option sets the Car Configuration File values above. It needs a Bluetooth-capable head unit or phone module. Where the hardware is present but the option was never enabled we switch it on; software cannot add hardware that is not fitted — we check your As-Built first and set only what your car carries.

Bluetooth Handsfree and Audio Streaming — model coverage

Earliest model year the options existed on each line:

Earliest model years the CCF flag existed on each line; availability depends on fitted hardware and market. We confirm by VIN before any change.

Two ways we switch this on — both remote, over OBD

Depending on model year and architecture, Bluetooth Handsfree and Audio Streaming is enabled by one of two methods. We pick the correct one for your VIN — you do not need to know which in advance.

• CCF editing over OBD — the BLUETOOTH HANDSFREE / Bluetooth / HANDSFREE TELEMUTE FUNCTION values (block 0x17 / 0x1B / 0x3A) are written over OBD to the module holding the CCF, then that module is reset so the new configuration takes effect.
• OEM-tool online configuration — where the module holding the flag needs its configuration re-issued from the manufacturer’s programming database rather than a direct CCF value, the same result is completed remotely through the OEM diagnostic tool’s online configuration for that module.

Either route is performed over the OBD diagnostic port, remote and mobile. Where the feature needs hardware your car does not carry, the hardware must be fitted first — software cannot add it. The change is reversible the same way.
