Hey guys.

I came across an ACM (audio control module) from a 502A. These of course come with HD Radio and the Sony system.

The question is, how do you add it to a non 502A? Here's my conundrum:

HD radio only exists on Sony's systems, which means they have a DACMC (Digital audio control module C) because all functions on the sony are digitally controlled.

This means that stuff like balance/fader and more importantly, volume, is controlled by the DACMC digitally. This is to say in layman's terms that when I connected the ACM to my 302A, it came up at full blast (and OMG does it distort bad at max volume), but with HD radio and all other features.

I tried using the as-built from a 501A and the everything now functions normally (including volume) but I lose the HD radio tuning.

Is there a way to program the ACM with the as-built from a non-sony (302A thru 501A) which wont include the DACMC and retain HD radio?

Thanks

 

I'm in to know as well. M

 

I would guess there is probably only one bit that needs to change to enable it. What one I'm not sure as I have not tried to find it yet.
