need to add tuner for 05 cs. have the pcm, but not tuner for phone. dealer here said he wanted like 2500 us$ for this. that sounds crazy! anyone know how much and where i could get this? for 2500- i will keep using my regular cell!
Sounds right, because Porsche does not have any pre-wiring done if the option is not ordered on the car. In case you have doubts, ask the dealer how much to install the 6-disc changer (and this is supposedly partially pre-wired!).
