When I looked at my fuse box there was no fuse in the slot
designated for cd player.
As was mentioned earlier in this Thread
Posi Taps for t connectors I ordered a few .
I am impressed by there quality and easy to use ness.
Fuse numbers function will vary by year consult your fuse map.
mine is 17 for the TCU and 18 for the cd player in an 06.
Also the fuse map was still in my car stored on the back of he
glove box rear cover.
If you looked at the BMW cd changer install part of the process is
to reroute the fiberoptics for cd changer into the active most loop
at the Most Hub. If you see no red light shinning out of fibers
going to the cd its not in the Most Loop.
Easy to check the light through the fibers just by shinning a flash
light in and looking for it to come out at the other end.
Also you may find these useful especially the first two.
