Hello, looking for some advice here. Sorry if this has already been posted/answered-- I did a search and couldn't find anything.

I installed the Octacore Android 3GB RAM MMI Navigation from RS Nav in my 2014 Q5. It works great, but there is a problem with the microphone when I am using Carplay. When I try to make a call or respond to text messages, it says it cannot hear me. Do I need to install an additional microphone or is there some setting I can change on my phone/unit?

Thanks in advance for any help!
