With the key in the off position:
• Connect the 16-pin harness with stripped leads into the interface.
Note: The potentiometer which is located on the 16-pin harness side of the interface is for future applications.
• Connect the 6525 harness into the interface, and then into the vehicle.
• Connect the climate extension cable into the connector behind the radio trim panel with climate controls,
and then into the vehicle.
Note: This harness must be connected for the climate controls to function.
• Connect the white round cable removed from the radio chassis in dash disassembly, into the Axxess interface.
Note: If this is not connected, the factory display screen will not function.
Attention! For models with a 4.2-inch screen, please update the interface via the Axxess Updater
available via axxessinterfaces.com. Select "4.2-inch screen" once prompted.
1. Locate the factory antenna connector in the dash, and complete all necessary connections to the radio.
Metra recommends using the proper mating adapter from Metra.
Note: If using the AXXESS steering wheel control interface (sold separately), connect it after you program
and test the 99-6525, with the key in the off position.
2. Initialize the kit by turning the ignition on until the radio comes on, then turn the ignition back off, then
back on again.
Note: If the 99-6525 loses power for any reason, this step will need to be performed again.
3. Test the aftermarket radio and climate controls for proper operation.
4. Mount the completed assembly into the dash using the 99-6525 radio trim panel with climate controls, and
then reassemble the dash in the reverse order of disassembly to complete the installation.
