Good notice David ! It's must be the button on the middle.

You say it is usefull but not essential. If i dont have this button, how can i whitch between "computer, nav, phone" and radio ?

I have another question, but nobody have the answer, if it's working, what will be display on the radio screen ?? Nothing ? Only Radio info ? Radio and nav as today ?... We will see in a few weeks.

I'll make a lot of picture during installation.
