Hi
I have an audi a4 1999. i am retrofitting cruise control using an aftermarket kit (not oem audi) and i need to give it a speed input. Does anyone know what signal the auto volume system on the conert radio receives. is it encoded or is it a simple pulse?
does the speedo signal receive a pulse for every revolution of the driveshaft?
jst wondering as it comes with a magnetic sensor which attaches to the drive shaft, but if i can use one of these signals then it would save a bit of time and hassle!
Thanks a lot /ubbthreads/images/graemlins/beerchug.gif
