I just got finished tearing apart my 2012 level 3 GL1800 to no avail! I took apart every connection on the passenger hook up and then took a part all connections for the driver. I do have a cellset, ground loop isolator in line to run phone, GPS and XM radio. I bypassed all of those connections and basically went back to bone stock to make certain it wasn't anything to do with my cellset that is causing my lack of muting capabilities.
I have to YELL to get the intercom to mute, even close to 19-20. My wife would go hoarse to be able to break the radio when talking with the intercom on!
I took my friends 2013 and added his helmets / my helmets to his bike and basically it's the same way! This is very frustrating to say the least!
It has been mentioned that 01-10's are different than the 2012/13/14? For those of us with a 2nd Generation GL1800, is there anything we can do to try to alleviate this problem....obviously, I'm not the only one having this problem... there has to be more out there like me?
Is there a recall on any part of the audio electronic system that would fix this situation that anyone may know of?
Thanking you in Advance!
