With new IPKs costing anywhere from £230 - £480 plus VAT, this is looking very interesting, the other thread offering a possible solution seems to have died a death.
I bought my 2nd hand one complete with the elusive stalk control for £60 (bargain , I thought). I would love to buy new but Rimmer Bros. quoted £480 + VAT.
I bought the 2nd hand one specifically to take apart and see whats what and with the hope that someone somewhere (if it wasn't me) would eventually figure out how to either hack it or "fix" it in some other way.
I want to use it to upgrade my car with message center, keeping my car honest at the same time (mileage wise), as it happens my 2nd hand IPK has done 177000+ miles, so there you go.
