Mr12Volt P600 Porsche MOST Fibre Optic Bluetooth Adapter for PCM 2.0/2.1, CDR23/CDR24 - Hands-Free Calling & Music Streaming - Fits 911 996/997, Boxster, Cayman, Cayenne - OEM Integration, USB/SD/AUX, BOSE Compatible

Factory-style wireless upgrade for Porsche optical audio systems

Give your cabin modern connectivity without ruining the original look. The Mr12Volt P600 integrates with the Porsche fibre optic network so you get crystal-clear digital sound, proper button control on the dash and steering wheel, and a tidy install that feels like it was there from new.

We have fitted and used this kit extensively at MJ Modifications and it has been a standout, reliable retrofit. Customers consistently praise the OEM operation, call clarity and audio performance through the original amplifier and speakers, including cars with BOSE.

Part number: P600

Key benefits

• Wireless calling routed through the car speakers with the included microphone for clear conversations
• Stream music and apps with track skip and play/pause from factory controls
• USB and microSD playback for MP3 and WMA so you can enjoy a music library without a phone
• 3.5 mm AUX input for additional sources
• Text display and menu browsing on radios that support metadata
• USB device charging direct from the module
• Retains original sound quality by using the Porsche optical ring rather than low-grade FM transmitters
• Discreet installation with no cutting of factory wiring

Important notes before you buy

• Cars with BOSE amplification typically work straight away on the optical ring.
• Non-BOSE cars must already have an external device on the MOST loop such as a CD changer, satellite tuner, external navigation or phone module. If none are present, a dealer will need to activate a compatible function to enable the interface.
• CDR24 systems require a factory CD changer to be installed or enabled for correct operation.

Installation guidance

• If an external CD changer is fitted, use the supplied optical loop to bypass it. The changer will be disabled after bypass.
• If an OEM phone module is also present, a second optical loop is needed to bypass that module so steering wheel phone buttons work correctly. One loop is included. Add another if both CD changer and phone module are fitted.
