That is strange, both AUDs shows the same SW part and configuration numbers.
What is you OEM settings for 028 ?
If it's 01, put it to 02.
If it's 02, (less likely) put it to 04. and reset the IHU and AUD.
If still you cannot hear from pin 02 (-) and 09 (+), either your IHU does not have the software to enable the AUD or the AUD you both is faulty.
Send an email to support, they might have the pre-amp software for your IHU to enable it.
