Just thought I'll create a thread for all of us to share some tips and tricks we use for our cars.I'll start:1) I like to turn off my iDrive (my 320i does not have navigation) when driving, so instead of pressing the 'Options' button then selecting 'Turn off display', I hotkey number 8 (by pressing and holding on to number 8 when turn off display is selected). So now, I just press number 8 and the iDrive display turns off.Any other tips and tricks to share?
