Sooo, I got my 3rd replacement NAV VI LM in September 2021. Got about 1000 “bike miles” out of it. Just sent yet another email to firstname.lastname@example.org to get my 4th replacement sent to me. I have consistently requested a NAV V (which actually work!) replacement, but to no avail. Stay tuned for the continuing saga of “The Ghosts of BMW NAVs Past”….
