I've seen some of the threads concerning the lack of Aux in on the 2007 Bravo, but I don't feel any the wiser, if anything, I'm more confused than ever. Firstly, how do I know if I have Blue and Me fitted? I don't appear to have Aux option on my head unit - it just scrolls between Radio and CD. I don't mind getting a replacement head unit, but how do I know it has the Aux capability before purchasing? I have pictures and model/serial numbers of several secondhand units, but I don't know how to tell just by looking, or even if there is a visual indicator. Help!
