Question related for parking sensors on Outback 2012. I have parking sensors in color of bumper so I will say that is factory bult-in. But that is just guess. I was in repair shop they check and sensors work when I put in reverse, but no beep beep sound and nothing happens on screen. I can not find in cabin any button related for engage or disengage parking sensors. I see somwhere some kind of service screen where is option for parking sensors but I dont know how to accses that screen. I have module with Denso dvd navigation. Its 2.0 diesel Swiss market. VIN no. JF1BRDLZ4CG113184 trim code J80 option code ECNE.  Nothing in instruction manual. Anybody knows something about how to enable sensors, some kind of combination of buttons or acsessing that service screen something else? Tnx for help.

Update, I found how to acsess to diag meny on Outbac 2012 Denso dvd unit. Start your car and everthing must be off on the display push left and right side three times. L+R L+R L+R there is diag meny. Some things about camera can be changed. But main part about parking sensors locked. Cant find a way to acess to that part of menu, service part.
