Ok… So after hours of research, I found a solution to adding an aux adapter on pre 09/2002 DSP business sound systems.
Here is a pic of X5chemist’s business CD player head unit.
In the pic you see all of the numbers referencing information regarding the part. His business cd build is 02/2006, with a software version of 47. Also, the e24 means it can decode MP3’s as well.
Here is a pic of my business CD unit that arrived today.
The pic shows mine is the same, although a month newer. The CD unit’s harness was direct plug and play. On power up everything was normal with DSP, radio, and CD changer no coding required. Steering controls work as well as dash display. Time to try CD mode. With an MP3 disk loaded and CD mode selected, track 01 began to play. Success!!
So this modification essentially converted my pre 09/2002 sound system, to a 03/2006 reaping all the benefits of the 2006 model DSP E53 factory system. What makes this special is, this was performed on an 01/2002. My E53 has the pre 03/2002 drivetrain and parts from the original design, now with the entertainment electronics from the final design. The best of both in my opinion.
I have ordered the genuine BMW aux adapter, and will finish installation when the part arrives. More pics soon.
Big shout out to X5chemist! Without your posts, I probably would have never gained this knowledge. Thanks!!
