here is the thing... its not hard to change from 3 series to 1 series. There is no 3 series XM kit either
BMW changed everything to fiber optic in 2005. The new MOST system is different from the electronics before. the E90 AND E87 may not be that different, but blitzsafe gave up on developing for the MOST system... thus no one hs a OEM looking XM configuration
