The Nissan Path

Hi all,
I've been battling with this for a couple of weeks now. I am not getting any signal through my radio... which i wouldn't normally be bothered about but im using an FM Transmitter to play audio from my phone.

I've read around and thought it might be the antennas in back passenger windows and from what I understand, the require a 12v supply?? Does this have its own fuse somewhere?

I've also read that there is a antenna amplifier located somewhere in the vehicle but I cannot find any documentation as to where this is situated.

Any help would be gratefully received.

Thanks
J
