GNC 255 no NAV audio

I just installed a GNC-255 using its internal intercom. I did a test flight. The COM is working fine, and the NAV radio is working fine for navigation (picking-up VORs and the HSI is reading correctly). However I’m not hearing any NAV audio (morse-code ID for VORs) on the GNC-255. I tried several VORs but not hearing the audio for any of them. Following hte manual I pushed the NAV button to activate ID and I turned the NAV audio level up, and verified that the display was showing “ID” active. Has anyone else using a GNC-255 through the internal intercom experienced this?
 
This thread can be deleted. I found the answer - there's a setting int he radio for "mix nav audio" which allows the NAV audio to be mixed with the com audio and heard through the headset.
