Thread: Why does my aerial not work?

I have installed an Alpine unit which has the same ISO connector as the standard stereo but it does not work... I have been told that whilst the Symphony II uses the other connector as well this is not needed. All the adapters I can see on the market are to convert either ISO to a banana type which is no good to me or the other one to banana type, which again is no use...
Anyone?

You have to supply power to the antenna amp as well which the symphony does, so you need a phantom power adaptor like this... which is ISO to ISO

Thanks, I found one in my draw and it is working!
