HMG feedback

I have the sc-25 receiver. Now that the 1.5 version is out, how can I
display what ever that shows on the front panel display of the receiver in
the home media gallery mode on roomie remote as a feedback.

While that model is not in the supported range for the new feedback, any feedback the receiver is capable of providing will be on screen. We ask all of the models to give us all of the feedback, so the absence of any particular portion of the feedback means it doesn’t provide that. You may find with that model that you will get feedback for things like AM/FM tuners and other radio functions, but full HMG feedback is very unlikely that far back.
