Power consumption

The power consumption of the BT Changer module in operation is 48 mA, in low consumption mode, 1 mA

The BT Changer works in low-consumption mode when not in operation. This means that if the digital communication on the car’s CAN-BUS system stops, the BT Changer module will also go into a sleeping, low-power state until the moment some data traffic (for example, the opening of the door) takes place. The factory CD Changer also works on exactly the same principle.


BT Changer module dimensions: 65 mm x 45 mm x 30 mm
