its awkaward to explain this but you need a little jiggery pokery . There should be 2 wires which need connecting the right way. on the standard block there fine for the vauxhall radios but not other makes. happens a lot this on vauxhalls, as you will find that the radios memory of saving your stations or cd tracks wont work either. ill have a look at mine and try to see what colours the wires are in mine later on., if somebody with better knowledge dosent post first., it shoudl be 1 or 2 wires which are seperate to the blocks with the singular fitments on. they need switching around.
