Nees to install this radio,please help as the original radio did not work,im not sure if its a fuse a wire or the device itself i,may need an adapter for this new 1 too out of a astra, please help guys much appreciated
If the fuse is ok then no need to change it. The oem radio is earthed on the antenna. After market radios aren’t so the iso cable has a seperate earth cable that you need to connect to the chassis
