I've been searching high and low for this, but couldn't find any solution. My Sony CDA-CA750X has a Bus Audio In.

I tried to connect my iriver mp3 to the bus audio in. problem is i can't select Audio In mode. Only FM and CD mode is selectable. Anybody know how to override this, so that i can select Bus Audio In Mode? (that means try to fool the head unit thinking that the MP3 player is actually a CD-Changer or MD)

Refer Image for illustration.

Any help would be very much appreciated.

Also, in the manual it says "This unit cannot be connected to a digital preamplifier or equalizer" .. does it mean i can't add preamp?

Thanks.

i don't get you.. what do you mean RCA output? thanx..

ok thanx. anyway , preamp is my last option. If i'm not mistaken, the player already has a preamp built-in.

prefer to find ways to connect mp3 player straight to the unit, since it already has an audio in. just need to find ways to hack it.. any help would be appreciated!

howiechoo, you're right, it would be worthless trying to mod the HU. I'm not even a pro to do this.

malutapimau, thanx for the info, i think XA-300 is the only solution. I'll try to look for it in KL. listed price USD 99, so here should be around the same. If you know a place, kindly direct it for me.
