Recently got this headunit but since putting it in for some reason it don't save the memory, it'll save for a couple of hours but after that all the radio stations and presets go back to default, weird thing tho is the time is fine, playing music from usb is fine plays where it left off, but when I get in the car in after leaving it for the night I'll get in the car in the morning and radio and presets all back to default, any help is much appreciated

I've been told the red Acc wire doesn't connect to anything as its got a canbus

It's in a 2009 a3 8p sline
