I had a 2010 Limited and my wife has a 2013 Street Glide both with 660's and the Harley Navigation Interface Module which allows the 660 to interact through the stock radio system. Last year the audible nav voice would periodically stop working on my bike, when this happened I would get a lot of static. Usually the system would function as normal after a gas stop which of course meant turning the bike off and then back on when we were ready to ride again. The 660 functioned as normal in the car mount. I've traded the bike in on a 2018 so I can't continue to duplicate the issue, although I continue to use the 660 in my car with no issues.
Now the 660 on my wife's bike is doing the same thing. I was thinking there was an issue with my 660 but since this has started to happen on her bike I'm beginning to think the issue is the HD module.
Dealer is not aware of any problems with the NIM but admittingly has seen very few of these installed.
Anyone one else experience anything like this?
