Audi Q7 4L MMI 05-15 Installation and Purchase Instructions

1. Before you order – how to ensure that your Q7 has MMI High

Signs of MMI High	Signs on MMI Basic / other
Color screen (6.5-7”) in the center console	Monochrome (red/gray) display or no display
Joystick on top of the dial + “RETURN” button	Rotary knob only – no joystick
Software version starts with “HNAV, HNav_EU/US” or “xx-HU” (see Setup → Version )	“BNAV”, “RMC” or no “Version” menu
The DVD navigation is located in the glove compartment (2G) or under the rear seat (3G)	RNS-E, Concert/Symphony or MIB radio

2. Contents & necessary tools

Included in the box	You must have it yourself.
10.25″ Android 13 screen w/frame	Torx T20/T25 screwdriver
Plug-and-play Quadlock/MOST wiring harness	Plastic trimming tool
LVDS video cable	Possible radio removal tool
CAN-bus box + microphone	10 mm key for battery terminal
(Optional) RCA cable for rear view camera	Spritus cloth for wiping fingerprints

3. Preparation

1. Park the car with the wheels straight.
2. Turn off the ignition and disconnect the negative terminal on the battery - this will avoid short circuits.
3. Apply the handbrake; be aware that the radio may ask for a security code if you later reconnect OEM devices.
   

4. Dismantling the original screen (≈ 15 min.)

Step	Do this.
4.1 Remove the air vent panel	Use plastic tool: pry at each corner and pull straight out. (Shown in video)
4.2 Unscrew the OEM screen	4 × Torx T20 behind the ventilation holes. Lift the screen forward.
4.3 Remove LVDS and power connectors	Press the locking tab down, pull straight back. Set the screen aside.

Tip: If your car has a BOSE/Bang & Olufsen amplifier, there is a fiber-optic (MOST) cable connected to the LVDS connector. Leave it in place - the new screen will loop the signal through.

5. Connect the wiring harness

1. Quadlock: Pull the OEM connector out of the MMI unit and click into the male → female bypass connector on the new network – no wires need to be cut.
2. LVDS: Connect the included video cable male/female.
3. CAN box: Mounted between Quadlock and screen; the box translates steering wheel buttons and parking sensors.
4. (Optional) Connect RCA to aftermarket rear view camera – the purple/white “REV” wire provides 12V when in reverse.

6. Installing the new 10.25″ screen

1. Click the metal clips on the frame into the original holes.
2. Push the screen in from above; make sure that the cables are not pinched.
3. Use the same 4 Torx screws to secure the screen.
4. Replace the air vent panel – press until it “clicks”.

7. First start-up & setup

1. Reconnect the battery → turn on the ignition.
2. The screen boots in 10-15 seconds. Select Settings → Car Type → Q7-MMI-High for correct CAN profile.
3. Set date/time → select Danish language.
4. Bluetooth pairing: “Audi-BT-Q7” → PIN 0000.
5. Apple CarPlay / Android Auto (cable): Use the USB port in the glove compartment. (Wireless module available for purchase → activate in the menu).

8. Integration of additional equipment

Accessories	Connection	Remark
Rear view camera	Yellow RCA “CAM-IN” + violet reverse trigger	Supports guide lines
Dash cam / DVR	USB or AV-IN	Recordings can be viewed on the screen
Front camera	“AV-F” input	Automatic display <15 km/h
MOST amp	No change – sound still goes through OEM amplifier	Use “MOST-AD” if you switch to an external amplifier.

9. Frequently Asked Questions

Question	Answer
Does the car need to be coded?	No – the CAN box learns steering wheel buttons, OPS sensors, etc. on its own.
Does BOSE/B&O work?	Yes, audio is transmitted digitally via MOST.
Do I keep car info menus (oil, service, etc.)?	Yes, they will appear in the “Car” app on the new device.
Can I keep the CD changer?	Yes – but if you remove it, the MOST loop must be closed with a bypass adapter.
Guarantee?	The device does not affect factory settings; can be removed in 10 minutes if the car is to be serviced/lease-returned.

10. Quick troubleshooting

Symptom	Possible cause	Solution
The screen does not turn on.	No 12 V ACC / battery disconnected	Check fuse #27 (radio) and Quadlock
No sound	Fiber loop broken	Check that the MOST connector clicks correctly; if necessary, use a bypass loop
Steering wheel buttons not working	Wrong CAN profile selected	Settings → Car Type → select “Q7-MMI-High” again
Rear view camera black image	No 12 V for camera	Measure purple reverse trigger; provide separate +12 V if necessary
