Sorry Mark,
But I have two (Mk2 and Mk2a) Players with 2.0B7 and V156. But If I choose form the "Knob Press Redefiniton" "NextSrc" there is no action on my quick press. But if I change to all other definitions it works.
Also if I have it on the PopUp0 Menu, I can see this name but after pressing the knob nothing happens. It goes back to the normal player screen.
I think that the Device have to go to the AUX mode, if the Tuner is not present. Or not?
Let me try it tomorrow in my car.
I really estimate your work! And the only think I try to do, is helping you to develop a great work.
bye
