car stereo CDX-MP37

[fbraun]

guys

I have a MP3 player and I'd like to connect it to the "BUS AUDIO IN" sockets on the rear of my CDX-MP37.

I was looking for an electrical scheme but could only find the one for the CDX-MP40. I do not know if the CD-changer sockets, including "BUS CONTROL IN" are the same for both models.

Anyway, on the schematic diagram of the CDX-MP40 I got the impression that it would do to just apply +12V (or other voltage?) to pin 5 of the said "BUS CONTROL IN" to get the CDX-MP40 to recognize the "BUS AUDIO IN" sockets.

Could anyone check if my assumption is correct and if the CDX-MP40 is similar to the CDX-MP37?

thanks
