I have got concert 1 I believe it is in my car?

I pulled it out today to find a right balls up wiring job, so I'm going to have to chop, solder and heat shrink the plugs back on properly

Chocolate blocks should be banned IMO

Anyway, Essentially I'm after a iPhone/iPod kit that will change the tracks through the head unit, that way I could leave my iPod in the car all the time hidden away or use the iPhone. Either way I just don't know which kit if any is compatable
