Technical Grande Punto Radio 12v ACC

[afonsosriv]

I just bought a second hand 2008 grande Punto and was installing a Bluetooth device in the aux module of the radio, the problem os that the radio doesn't seem do have ACC (accessory 12v), i could only find VCC (Battery 12v) which is always on and I don't want the Bluetooth device draining the battery. Radio Diagram and Info in the attachment, do you know where can I find the 12v ACC? The device is currently connected to the "Ub" port which I assume is the VCC.

Thank you in advance.
