Just installed a 187b unit with rear usb into my Polo MK5 6R, as it is a 2011 model i thought it wouldn’t have any battery drain issue but i left it overnight and it has likely drained my battery to the point where the power steering wouldn’t even work.

To check if the radio was on even without ignition, i have put in the wireless CarPlay adapter and it was constantly receiving power. I have now put the old radio back in as a control to make sure that it was 100% the radio’s fault.

It seems like i need a CANBUS emulator, but i’m not paying $44 for one from rcd330.com

Can anyone recommend any other similar products that would do the same job? Or even another solution? Fitting a new CANBUS would be just too much of a hassle.

Thanks
