Sat Nav screen gone bonkers (Z4M)

[ian in lancs]

My Sat Nav screen went bonkers tonight! Never happened before and turning the ign off & back on again seemed to have sorted it. Anyone else had this?

Yup, the screen in my e46 did this twice in a week about 2 years ago. Each time I shat my pants, turned the ignition off and on again and the screen was fine afterwards. Never did it again and I had forgotten about it until I saw this thread.
