I am re-submitting my first post because it was placed in the wrong category and might not have clear what I was asking help for. Is it possible to activate the reverse camera guide lines through settings in the Engineering menu? I will never understand why they are not standard with the camera. I've read several older threads on trying to engage the reverse camera guide lines by using the settings in the Engineering menu and I'm stumped. I get as far as the SVRC section but other than 4 other settings in that sub section, that I don't understand there doesn't seem to be a setting to turn on the guide lines for the C300 as there are with other MB models. Can anyone out there lend a hand? Thanks in advance.
