If you do that you'll lose the sat nav and it is so worthwhile having if you do any amount of driving. I wouldn't have a car without it now I have had it in my last Punto and this new Stilo. If you can find a decent car audio place they may be able to rig some sort of seperate jack input for you and link it up to the connections at the back of the car but I think it would be quite a job to do!
