I've got mine last week
A professional installed the unit, there was few problems with it:
- One of the pins was shorter in a connector, didn't connect when he plugged in, and no sound because of it, but he fixedd the issue.
- The right - left labels were switched on the connectors, but he realized so it's fine now.
- The wheeldrive buttons are working, but a cannot use the buttons around the knob, are yours working out of the box, or you had to configure them?
- If i call somebody through bluetooth, they don't hear me, but i hear them, wonder if it's an external microphone connection problem, or settings related. I have the BC8 option checked, and the BC6 unchecked. The internal mic is working, i installed a sound recorder to try.
