Bought a 2003 Z4 with homelink buttons on the bottom left of the rear view. It has power (LED lights up). How do I program it?
Didn't see a video specific to an '03 Z4, but there's probably one there that should get you going. It helps to have a later model garage door opener. Homelink apparently won't program old Genie openers, my mom's dates to the 70's, possibly older - no go on that, https://www.youtube.com/results?search_query=2003 bmw z4 garage door opener Or, look up you owner's manual here - procedure presumably would be there - http://wedophones.com/Manuals/BMW/
Go to homelink.com and put in your vehicle and opener. Should give you step by step on how to program. Newer garage door openers will not work with older vehicles without a adapter.
