Hi I have a 2007 (57 Plate) Seat Leon, I'm trying to work out how to be able to play music through an aux output. The radio itself doesn't have an aux output, but does have a 'CD/AUX' button. There is an aux cable coming out of the glovebox and a micro-usb port (i think), but this does not work and i have a feeling this is something to do with the bluetooth hand-free phone thing which is installed, which i know doesn't make sense but it's the only thing I can link it too in my head, that also doesn't work from what I can tell. I see on other forums that if you do have an aux output installed it can drain the battery and also the stock radios installed before 2008 won't support aux anyway. Is there any way of getting this aux output installed without having to buy a whole new radio and the thing that's required to not drain the battery or am I better off burning a whole load of cd's? Replies will be greatly appreciated, cheers!
