Hi Team.... I want to first tell you that I actually did read each even every page of this thread (some more than others) - you folks are amazing.
but from this thread I cannot fully tell if its safe for me to purchase a 4000NEX and upgrade it fully to a 4100NEX. My only reason for doing this is to have Android Auto working (and not losing all kinds of other function)
Are we there yet? (and definitely willing to make a donation if required) and is there still hope to actually get there?
