    Product Details

    Mr12volt P600 for Porsche is installed on the OEM radio via Fiber Optical system (MOST). It therefore delivers high quality sound just like your original CD. And with this seamless integration, you can control your songs from your favourite app (such as Spotify, Deezer, Pandora, iTunes, YouTube...) through your radio buttons and more importantly the steering buttons.

    Compatible Porsche Models: 

    911 (996 MK2/997) 2003 - 2011, Boxster 2003 - 2010, Cayman 2003 - 2010, Cayenne 2003 - 2010.

    Compatible Head Units: 

    PCM 2.0, PCM 2.1, CDR 23 (with CDC), CDR 24(with CDC).

    Important Compatibility note:

    If the Porsche has a BOSE system, Mr12volt will work out of the box, otherwise it must have an external device, such as a CD changer, Satellite, external Navigation or Phone module in order to function. Without it one of the mentioned functions must be programmed by the dealer to activate support for Mr12Volt unit.

    For CDR24 there must be a factory CD changer installed, otherwise the P600 will not function correctly.

    Installation note:

    • If the Porsche has a external CD changer, an optical loop connector (1x pc supplied in this kit) is needed to bypass it. (CD changer will be disabled after bypass)
    • If the Porsche also has an OEM external phone module, an additional optical loop connector is needed to bypass it in order to have the phone buttons on the steering to function properly. (Package comes with 1x optical loop connector, you will need to purchase another one if you have both CD changer and Phone Module)
