1991- Early 1994 BMW vehicles which have CD Changer Controller radios and are fitted with a 14-Pin data cable which is terminated in the trunk are compatible with the Pioneer CDXM30 after market CD Changer when installed in conjunction with PIE Part # BMW-PIO/M CD Changer Interface Convertor. One end of the BMW-PIO/M adaptor plugs
into the 14-Pin OEM CD data cable and the other end plugs into the Pioneer Changer's 2X7 chassis plug. Use of the changer's after market data cable is not necessary and is superfluous.
