Retrofit Car Stereo Installation- Porsche ISO Adapter Cable
Porsche ISO to ISO radio replacement adapter harness. Built in CANbus ignition interface that gives a key present ignition supply to the new radio.
This harness is designed to give CAN ignition and an optional Speedpulse output if needed on navigation head-units. It will also give audio in cars that have speaker wires in the original ISO connector. There is an amplifier turn on wire on this harness, this is for cars that have a non Bose amplifier that receives a normal speaker level audio signal from the head unit. This ISO adapter harness is suiteable for Porsche 911, Boxter (987) & cayman (987) fitted with the original CDR24 or PCM2/2.1 audio systems.
NOTE: This harness will not retain audio in cars with Bose audio systems as there is no speaker outputs at the head unit, these cars will have a fibre optic connection from the head unit to the amplifier, a different interface is required.
