So, I'm driving today on the speaker phone w the nav system running in the 2016 LC. The call gets dropped, the screen freezes. Can't get it to do anything didn't respond to touching the screen, tried using commands from the steering wheel buttons. No result except the little center screen said "processing". Then about 15 mins later the big screen goes blank then says something about a disc and a graphic came on the screen that said something like "reloading, don't turn off power". Anybody else experience this. Is this just something that happens and I have to live with or take it to the dealer or is some other action required?
