Hi.
Does enyone have solution for title problem. Dension and connects2 products are tested. Works other way good, but without sound. DSP is the problem?
Does anyone have shematics for the radio?
Unit is model CD54 manufactured 21.02.2003 sw version 9.50
Does main unit sends audio to amplifier in digital format?

If you're not getting any tunes through your AUX, it's probably down to the DSP being a bit tricky. You might need a special gadget that'll take your AUX's sound and change it to a type that the DSP amp can understand.

Do you have any idea where to get that kind gadget?
