Hey I've been trying like a bear to get this done. I have this HU in my car http://fiatforum.com/gallery/data/2786/1_removal.jpg
I have no blu&me nor and aux input anywhere. I've read aparantly you can still get something plugged into the back of the hu enabling me to use mp3 through aux-in?
For example I'm thinking of just buying this.

And see I can fit it? Any advice? Has anyone else fitted aux to this kind of HU ? If so plz help.
