Yes, ACC parts costed below 900, including steering wheel (heated
, DSC, ICM, ACC sensor and brand new lower grill.
Night Vision hardware was sth around 1500$, but I was quite lucky to get almost complete set from one seller.
As far as I recall somebody was writing that DSC ACC has 2 extra sensors inside. No clue for what reason.
As far as I recall KAFAS is only preparing brakes, by raiaisng the pressure, so when you press the pedal is brakes sooner.
