Installation; Programming; Final Assembly; Audio Level Adjustment - Metra Electronics 99-6520B Installation Instructions Manual

INSTALLATION

Attention! For models with a 8-inch screen, update the interface via the Axxess Updater available
at axxessinterfaces.com. Select "8-inch screen" once prompted to. Instructions to update the
interface are available at the end of this instruction booklet.
With the key in the off position:
1. Connect the 16-pin harness with stripped leads, and the 6520 harness, into the interface.
2. Connect the factory "White" 4-pin harness removed in step 4 of Dash Disassembly to the
"Black" connector from the interface.
Note: The display screen will not function without this connection.
3. Connect the 6520 harness to the wiring harness in the vehicle.
4. 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 an ASWC-1 (sold separately) will be used, do not connect it until the interface is
programmed and fully functional.

PROGRAMMING

1. When the interface first boots up, the factory screen will go through a boot up sequence for
a few moments. Do not touch any controls during this process.
2. Test all functions of the installation for proper operation, before reassembling the dash. For
amplified models, also refer to the "Audio Level Adjustment" section.

FINAL ASSEMBLY

AUDIO LEVEL ADJUSTMENT

For models with a factory amplifier:
1. With the vehicle and radio turned on, turn the volume up 3/4 of the way.
2. With a small flat-blade screwdriver, adjust the potentiometer clockwise to raise the audio
level; counterclockwise to lower the audio level.
3. Once at a desired level, audio level adjustment is complete.
