mkiii nav blank screen radio ok
My symptoms - blank nav screen but radio, cd working fine all buttons both sides operational. The nav screen was working fine. (went off during a journey actually). I have updated the screen from 4:3 to 16:9 but was still using the original mkii nav unit. This set-up has worked fine for several months until now.
Things I have tried - shutting down and removing from power overnight, powering back up and re-installing with older os (v17.1, v18). Nothing.
My thoughts: Does the nav computer need to have the original screen when re-loading software? Or does this point to the screen being faulty? Or is it the nav drive dead?
Any ideas?
