BMW / Mini antenna adaptor

I need to find an adaptor that will convert the antenna connection in my Mini to the kind on the empeg tuner. I can get one that goes from the Mini to an american style antenna plug but then I would need a second adaptor.

If you don't know where I can get one does anyone know what the plug on the empeg tuner is called ?

I think this is what you want.

Notice I said think. Wait for a 2nd opinion before ordering.

That looks like the adaptor that comes with the empeg tuner. I should have taken a picture of the back of the stereo.

The antenna plug looks like a XM radio antenna connector like this . So I need one that goes from that to the kind on the empeg tuner.

The ones I have found have the goofy plug on one end and the kind most american head units use on the other. I could use one of those but I would need a second adaptor to connect it to the empeg tuner.

Here is another one. I need this with the female end replaced with the end to connect to the empeg tuner.

Couldn't you just use that along with the antenna adapter that came with the empeg? I know it's not ideal, but....

Yeah if I can't find the cable I am looking for I will have to use two adaptors.
