Well this week i got a bit fed up of the alana headunit and had a few quid spare so bought a Sony CDX-GT200, yes its not the best but I got a decent price for it and a few little things thrown in so anyway it comes in the next day or so. I have searched this before anyone asks and this is more a confirmation post, I have heard I need to swap the red and yellow wires and thats pretty much it. Is there anything else I should be aware of and anything else I might need
