other than a dealer visit is there a diy way of activating the drl function...mines a 05 touch screen head unit ...i dont know whether the stuff in the back is bmw or not but its got landrover labels all on it....
Daytime running lights. Not sure how it was with the BMW system, but on recent model years with Ford/Denso electronics (touchscreen navigation, etc.), I'm afraid the only way to get those enabled in markets where they are not mandatory is through diagnostics - either at a dealer or an indy shop equipped with them.
I know I've seen someone compile an inclusive list of the dealer-only selections and it's in the forum somewhere. I looked in my saved files, but apparently I didn't save it. It was a year or so ago. If you do a search, it'll come up somewhere.
It's hard to get one from a dealer (mine, anyway). On my first service at my local indy mech., He and I went through the menus while he had Testbook hooked-up, because he had nothing in writing on what selections there were. I took my choices as we went through them. Some I expected thanks to this forum, and there were a few unexpected that came up too.
DRLs is an option on the '03 as well, and I planned to have him turn it on, but he talked me out of it.
