MLink Installation Guide
Disconnect the Battery
All models
Locate the battery in the trunk. Remove the terminal cover and disconnect the negative (-) terminal. Wait at least 2 minutes before proceeding.
Hybrid models (MHEV / PHEV)
If you have a hybrid model, it has a second 12V battery at the front of the vehicle. Disconnect it as well before proceeding.
Steering Wheel Button Installation
Remove the airbag
Insert a 10mm socket into the access holes on the rear of the steering wheel and undo the two airbag bolts. Carefully pull the airbag forward and disconnect the connector.
Remove the front T20 screws (2x)
Using a T20 Torx bit, remove the two screws on the front face of the steering wheel.
Remove shift paddles (if equipped)
Pull each shift paddle toward you to unclip it, then disconnect the connector.
Remove the rear T20 screws (2x)
Remove the two T20 screws on the rear of the steering wheel.
Remove the steering wheel trim panel
Using a plastic pry tool, carefully release the trim panel that holds the OEM volume and phone buttons. Disconnect any connectors.
Remove the top steering wheel cover
Lift the top cover away from the steering wheel hub.
Install MLink buttons
Seat the MLink button unit in place of the OEM trim and secure with the T20 screws. Route the wiring harness down through the steering wheel column.
Reassemble the steering wheel
Refit in reverse order: top cover, trim panel, rear T20 screws, shift paddles, front T20 screws. Reconnect the airbag connector and press firmly until it clicks.
Controller Module Installation
Remove the center console trim
Using a plastic pry tool, carefully remove the center console trim panel to expose the gear selector module.
Undo the 4 x T20 bolts on the gear selector module
Remove the four T20 bolts holding the gear selector bracket.
Connect the MLink harness to the 4-pin connector
Locate the 4-pin connector on the gear selector module. Unplug it, then plug the MLink harness in-line: car-side -> harness -> module.
Disconnect the 18-pin connector
Disconnect the 18-pin connector from the gear selector module.
Release pin 12 from the 18-pin connector
Using a toothpick or pin tool, press the retaining tab on pin 12 and gently pull the wire out from the rear of the connector.
Insert pin 12 into the MLink harness
Push pin 12 into the corresponding slot in the MLink harness connector until it clicks.
Reconnect and tuck the module
Reconnect the 18-pin connector to the gear selector. Tuck the MLink controller into the center tunnel, away from any moving parts.
Reassemble
Refit the 4 x T20 bolts on the gear selector, then reinstall the center console trim.
Reconnect Battery and Verify
Reconnect the battery in the reverse order of section 1. PHEV models: reconnect the front 12V battery first, then the trunk battery. Start the vehicle and verify that the MLink buttons respond correctly.
Configure Button Profiles
Download the MLink app
Download the MLink app from the App Store (iOS) or Google Play (Android).
Enter configuration mode
Press and hold both M1 and M2 buttons simultaneously for 6 seconds. You have 30 seconds to connect via the app before the controller resumes normal operation.
Connect and configure
Open the MLink app, go to the Connect tab and tap Scan. Select your controller, then navigate to Profiles to set the desired drive mode for M1, M2, and M1+M2. Tap Update Controller to save.
Troubleshooting
Airbag does not sit flush after reinstallation
The airbag clips onto three spring-loaded pins. If it appears uneven, remove the airbag again, locate the T20 bolts holding the spring mechanisms, and make very minor adjustments - a small turn is enough. Reinstall and check.
