Cant wait to see the DIY write up on this, been trying to figure out how to do it since we got the X5 2 months ago. Hopefully your "new toy" is a orange computer that can change settings for the on board computer, call it a euro option call it what u want, all I know is Tom at EAS hooked one up to the X5 and now the DRL are off and the windows rolldown AND up remote from the key!!!
