Hi. Trying to get the aux working on my cls 320 2009. It's radio only with cdc not command touch screen. Have plugged the lead in the back of the radio and plugged it into my dab. But can't get any button to work to go to the aux input. If I press and hold the cdc button it just starts to ay the cds, it's the same with all the buttons. I have held the button down for 10 seconds on each but no joy. Any ideas or does the radio not have that function.
Thanks
Thanks
