For Crowz (or anyone else might know)...

I have two wiring questions while I am working on the problems I caused elsehwere. Someone removed the factory BMW radio and replaced with a JVC when I bought the X5. JVC is coming out and the XTRONS (model PB7653BP) going in. This XTRONS sure appears identical to the Seicane. I bought the Xtrons (from Amazon) before researching this thread. XTRONS documentation is awful. So because the previous owner pulled the factory radio this is not quite plug and play and is taking a slight reverse engineering. This is 90% done being wired and installed right now.

Question 1 - which Seicane/Xtrons wire is for the steering wheel control?
So regarding the photo of all the wires on https://xoutpost.com/bmw-sav-forums/...hread-114.html (page 114 of the thread) for the BMW connector: At the top left there is a blue wire on the left and green wire on the right (left bank of wires the radio operations; right bank for speakers). The question is - is the green wire for the steering wheel control or the "KEY1" brown wire that is loose/seperate from the connector? Or am I wrong on both :-)? The XTRONS comes with the CANBUS decoder as pictured.


Question 2 - where did you pick up a signal/wire from for the radio illumination? I saw one post designating BMW-Gray/Red for nighttime illumination (I see this on the Blue BMW factory connector) so I think this is correct however there was another Black wire mentioned on that thread for "background illumination" and I don't want to screw up. https://xoutpost.com/bmw-sav-forums/...ml#post1124010

I tried my best to search on these and could not find this previously answered to the letter. Thanks! -Todd
