Hi there I have a 06 grand voyager 3.3XS stow n go and the original satnav unit does not work and I would like to change it for a 7" double din unit, I have done it on a 03, I can mod the housing to physically hold the unit! does anyone know if the is any wiring differs from an 03 (I know about the relay that needs shorting ) and are there any leads available to connect the steering wheel controls. Many thanks Dave
