Hello all, I was just curious if anyone new what the "memo" on/off did on an X5 Radio/Navigation system? There is no mention of this in navigation manual.

Just to clarify, if you have navigation system, when you go to settings, you can scroll through on setting the langauge, miles, clock , date, and the last setting shows "memo" on/off. When you click "on" you see couple of swiggly lines on the bottom of the screen. What is being memorized?
