As a follow up, I was upgraded to the Nexia 9 back in August from a Nexia 7. As a side note- I will say that I actually can tell a difference in the sound especially in background noise when I compare the 2. So all was going well, then this week my Nexia 9 had the same problem again. I went to my Audi and they now have case replacements for the HA- which fixed the problem. Ends up, for some reason the external microphone barrier/guard (not the M&RIE) is not able to release the moisture in this model. Apparently the tiny mic hole in the top of the HA has a filter, but it easily gets clogged. So now they can swap out the outer casing of the HA, which has that filter built into it to protect the actual microphone. My Audi did this and it worked again right away. Atleast we now have a remedy for the future if this keeps occurring. Does anybody know if buying a can of compressed air could help clear this out?
