Hello! I don't own an X5, but I do own a BMW. My 2000 323i has keep me busy for the last 3 years. If I could afford it, I'd sell my tahoe and get an X5
In any case, I do alot of work on BMWs (specifically DDEs) and have done more and more work on X5s. I've always looked at this board, but never become a member, so now here I am. If you guys have any questions about lighting or aftermarket electronic installs, let me know and I'll help out the best I can.
Here's the most recent X5 DDE setup that my co-installer and I did yesterday:
