When I was driving our rig yesterday I noticed what looked like a little oil can icon displayed on the Panasonic CRT rear-vision camera on our 2003 Holiday Rambler. Our rig has a TripTek computer, so I'm assuming the TripTek is what put this icon on the display. However when I look through the the TripTek operator's manual there's no mention of any icons being involved. Ours is a model 2500-3T TripTek. Does anyone have any info about how this icon came to be displayed on our rear-vision camera? Thanks in advance...
P.S. I find the display of the current gear in the Coach Data screen to be helpful, it helps me to know if I'm in 6th gear or not.
