As a follow up to the steering wheel adaptor, it appears almost all the buttons work. One button needs to be held down for a second or two before it works. The real weirdy is one of the preset buttons. It only appears to work when the tuner is at a certain preset. At all other times it is ignored. This can even be demonstrated with the Button Codes Display. Spose I should finally update to 2.0 Final and latest hijack...
