The BACK CAMARA /SCREEN/ GAGES, COMPASS.
Somehow we ended up with every thing mirror image, not a big problem unless U need a quick fix on how the car is doing in a turn, then a little unnerving.
Reading the book, no help. Using the r-l, then L-R etc could get the car on its side upside down bu t never to natural same for the compass, gages.
Turned on off, both on the Jav & the dash. etc.etc.
Found something said might be a switch on the Camara [which had been replaced] no luck.
Opened the Center hatch, maybe a switch on the CPU. No luck. With that open saw a on/off switch on the side of the monitor. Turned it off, the other 2 switches Off. Spoke to the electronic gods. Turned every thing back ON, all 3 off switches.
Started working the R-L buttons. Went back to Normal that switch on the side must allow ttl. Reset of the CPU.
JUST A FYI
