HU-650 Grom audio parasitic draw
After the car is switched off and to sleep the grom unit (without bluetooth) keeps drawing current (connected usb keeps blinking) when disconnected parasitic draw is gone .Its connected via the back of the HU-650 unit .
Any guesses?

Ok i pulled the amplifier fuse (30 amp) nr 11 side of dashboard .
Grom is switched off now when car is asleep.....everything else is still working even the radio settings when turned on again no quality/volume loss
Also when i put the fuse back in with the radio on...no difference or current trough the fuse(no milli volts).
Im happy for now..
Out of curiosity where is it used for? external amplifier? volvo amplifier?
Without the fuse everything seems "amplified"
