Backup camera image missing red, yellow, green proximity lines (1 Viewer)

[DIFF LOCK]

I have a 2004 TOYOTA Land Cruiser with factory navigation and backup camera. I see images of the backup camera screen on both older and newer Land Cruisers and they have the colored proximity lines clearly showing. Mine doesn't have these. Is this a feature I need to activate in a hidden menu?

If you see those lines in older Land Cruisers, they probably have a newer backup camera system. I have never seen those lines in 100 series factory system.
