M072 (S160) Android Head Unit Install/Info

[Tonto]

Hi guys, i've just ordered the M072 unit. I have one doubt about it, though. Do i really need the external microphone? Because it seems the unit has two small rounded holes next to the screen (left side). I've had a chinese unit on my previous Astra H which also had those small holes which were the unit internal microphone, so chances are we don't need to plug the external microphone. Can you confirm this? I'm asking this because the external mic it looks ugly to me.

Btw: awesome @tonto looks amazing and i've just ordered the dual USB socket to replace the rear lighter. But i have here a doubt:

Straight forward really! I took off the rear trim and snipped the cig lighter wires and took it out. The spliced the new wires from usb socket into existing wires.

How did you remove the rear trim? I'm afraid of breaking something...

Hi,

Slide front seats forward and on the rear trim you will see the line where you can slide a trim tool in to prise it open, it was a little stiff at first but does come off. Once you start you'll realise it's very simple.

Where I've circled you can see the line where trim joins.



You don't get much room once it's off until you unplug the wiring for cig lighter.
