2012 Impreza 2.0i HB

Default Non-navi head unit (CM631UD) Camera adjustment

Just in case this isn't common info (i don't think anyone has posted the details), here are instructions for accessing the service menu for the Impreza Limited (4.3" screen, HD Radio, no navigation) radio to configure and adjust the rear backup camera.)

i should note that i didn't figure this all out on my own: it was through many helpful posts here and elsewhere (STI/Forester/BRZ forums) and just a bit of experimentation on my own that allowed me to figure out what to do for this install and how to adjust the rear camera)

To access the service menu:
Ignition key to ACC
Turn Head Unit to Audio OFF
Hold Preset 6 button and simultaneously
Rotate TUNE/TRACK/CH knob clockwise about 5-6 turns
See Version Information screen (release #6 button)
Press knob (MENU/ENTER)
See Firmware Upload screen
Press knob (MENU/ENTER)
See rear camera marker adjustment screen

You are now ready to adjust the rear camera or can just use this screen to view the camera without putting the car into reverse.

1. To adjust guidelines positioning
Hold MENU/ENTER knob/button
Four red arrows should appear indicating that the parking guides can be adjusted
(release knob/button)

Use following these controls to adjust lines:
- TUNE/TRACK/CH knob - move lines up (CCW) or down (CW)
- >> Move lines right
- << Move lines left

Press MENU/ENTER - this will exit the line-adjust mode

2. To turn on and off various features using Numeric Keys

(when not in line adjust mode)

2 - switches between French/English warning
3 - choose between one of four Parking guide marker/line styles
5 - move the warning text to either top or bottom of the screen
6 - turns parking lines/markers on or off

Exiting Service menu
Finally, Turn ignition key OFF and wait 60 seconds or more to write new settings. Do not turn on ignition key or disconnect battery during that time.

ps. i wrote incorrectly in a prior post: you cannot apparently turn off the warning text. you can only move it to the top or bottom of the screen from what i've figured out. on the other hand, the lines can be adjusted and/or turned off as noted in the above instructions.
