Yes, I could 'just'.. if I had the car.. :P I just have the Radio.. I'm wirring a CDR-220 radio in my Sched..
No point of trying this on my 987, the radio system is completely different. and I don't feel like taking the dash appart.. :P
But I asked to a buddy who is specialised in Car Electronic, and he told me that usually the VSS (Vehicule speed signal) is Digital (Hall Effect), he din't know if there was a standard. Unfortunally, he's specialised in Toyota/Nissan/hyunday, not Porsches.. so he could'nt help me more than that :P
I was thinking I could 'fake' the Vehicule Speed Signal input of the radio (if it was a voltage with a reostat) to add myself a 'remote volume control', but I guess I'm gonna pass my turn on that one..
