1. No, there's no way to modify the firmware.Yes, we know it. thx!
Let me say it by a other way...
We need a AUX INPUT DIRECTLY at the PXA-H800 (at EQ/Div -Mode).
does anyone have a firmware mod or so?
Thx to all!
2. You cannot get AUX access any other way.
Please, re-read the responses from Bill and I above.
You have 4 options so far for getting an AUX input. 5 if you add using an analog-to-digital converter to send it via a TOSLINK connection with the head unit in CD mode.
If you absolutely must in only using the built-in AUX inputs, you'll have to disconnect the Ai-Net connection and use the RUX controller.
What is the requirement for using ONLY the built-in AUX jacks?
