AUX INPUT FOR STANDARD AUDIO E 53
 

Does anyone have good pics/diagram of where the auxiliary input connection goes in the head unit/CD player? I have an '03 E53 standard audio NON NAV NON DSP. I can't find this anywhere on this blog. THANKS!

The actual aux input cable connects on the back of the business CD into one of the connectors. Search for Au Input and it you'll find a number of great posts on it along with pictures.
