that is useless for you one member got told by lexus to fit sat nav to his car he would have to pay nearly 7k!!you need the whole wiring loom to fit this...if you give stav a pm im sure he'll sort you out...you can sent him the unit and a sony sat nav and he'll build you one for some pennys..i have one of his sat navs fitted and its never let me down..
then you can sell the sat nav boxes
