That's what I thought initially, but I know that other X5 owners have this working. For example:

The manual shows installation of the unit in an eject box that looks exactly like the one in my X5. Also, since this emulates a v60, shouldn't this work anywhere a v60 is used?

I am currently trying to find an old v60 that I can use to test the normal functions of the eject box and CPT system...
