CDR23 into MY1999 ?

Recommended Posts

  • Admin

The CDR 23 anti-theft will check the DME for the correct handshake to operate -- problem is your DME does not have that capability.

MY1999 has DME 5.2.2 for C2 and DME 7.2 for C4.

CDR 23 requires DME 7.8 which started in MY2003.


Besides the CDR 23 has MOST (fiber optic communication) so it likely will not work with your CD changer either.

Thanks Loren - confirms what I thought.


Though I understand that a CDR23 can be made to work without any handshake (for a price)  - DND Services in the UK can flash the MOST-BUS to achieve this. http://www.dndservices.co.uk/porsche-cdr23.html


Was interested because I saw this :  http://www.ebay.co.uk/itm/PORSCHE-911-996-9m-Carrera-Club-Sport-GT3-style-Track-Car-Huge-Spec-/301712979420?hash=item463f7eb5dc


Obviously not working a CD changer..
