Photo 2/36 | Alpine Direct Fit Kit 01 | Here is Alpine’s ’18 X-Perience Toyota 4Runner demo vehicle, complete with custom vinyl wrap to draw attention from the outside. But it’s really the audio system on the inside for which Alpine is known.
Photo 3/36 | Alpine Direct Fit Kit 02 | This is what the Toyota started with: a factory head unit with many integrated functions, but nowhere near the screen size and capabilities built into the Halo9.
Photo 4/36 | Alpine Direct Fit Kit 03 | The side trim is removed to access the HVAC panel. This piece is held on with clips, so it comes out fairly easily.
Photo 5/36 | Alpine Direct Fit Kit 04 | Then the HVAC panel is removed to access the factory radio bolts, and the bolts are loosened using a 10mm socket.
Photo 6/36 | Alpine Direct Fit Kit 05 | The full center panel containing the stock radio and vents is pulled out and can be setaside after unplugging the factory radio harnesses and other connections.
Photo 7/36 | Alpine Direct Fit Kit 06 | Some parts need to be removed from the factory unit. Starting with the top tray, the two small screws are loosened and set aside for future use. The top tray is also saved and reused.
Photo 8/36 | Alpine Direct Fit Kit 07 | The vents are removed by unsnapping them from clips. These are saved and will be fit onto the new unit.
Photo 9/36 | Alpine Direct Fit Kit 08 | Moving to the smaller parts, the air vent adjuster cover is removed and the screws and adjuster covers are saved.
Photo 10/36 | Alpine Direct Fit Kit 09 | The wiring harness for the clock is removed and put into the growing pile of factory parts that will be replaced with the upgraded Alpine kit.
Photo 11/36 | Alpine Direct Fit Kit 10 | For the last step on the old unit, the hazard light switch is unclipped and set aside.
Photo 12/36 | Alpine Direct Fit Kit 11 | The steps taken to remove parts from the old unit are now reversed—beginning with the installation of the air vent adjuster covers in the Alpine bezel, along with the top tray and air vents.
Photo 13/36 | Alpine Direct Fit Kit 12 | The kit comes with the head unit already attached to the dash piece, so once the factory parts are screwed or snapped into place, the fully assembled Alpine kit is ready for install.
Photo 14/36 | Alpine Direct Fit Kit 13 | The system comes with a full plug-and-play wiring harness and all the necessary adapters to work with your factory-installed options.
Photo 15/36 | Alpine Direct Fit Kit 14 | To begin the wiring process, the hazard light switch snaps into place on the front of the Alpine bezel.
Photo 16/36 | Alpine Direct Fit Kit 15 | On the back of the unit, the clock wiring harness that was set aside earlier can be plugged in, followed by the main Alpine harness.
Photo 17/36 | Alpine Direct Fit Kit 16 | In order to use all the available factory options with the new unit, the backup camera adapter is plugged into the harness and the SiriusXM adapter is plugged into its corresponding plug.
Photo 18/36 | Alpine Direct Fit Kit 17 | The cable for OBD2 is routed down to the OBD2 connector. This will give the user access to factory gauge readouts and other functions.
Photo 19/36 | Alpine Direct Fit Kit 18 | Next, it was time to choose a location for the Bluetooth microphone. The Alpine crew chose to put it just outside the upper cabin controls located on the headliner. Then they ran the cord and tucked it behind the factory panels to route the cable down to the radio cavity.
Photo 20/36 | Alpine Direct Fit Kit 19 | The Alpine main harness was then plugged into the 4Runner OEM radio wiring. Each individual harness connection is different, so it’s just a matter of matching them up correctly.
Photo 21/36 | Alpine Direct Fit Kit 20 | The USB adapter is then plugged in and will allow access to plug in external devices.
Photo 22/36 | Alpine Direct Fit Kit 21 | After running the wire down from the headliner and putting the upper factory control unit back in place, the Bluetooth microphone can be plugged in.
Photo 23/36 | Alpine Direct Fit Kit 22 | Then the factory radio antenna adapter and radio antenna amplifier are plugged in.
Photo 24/36 | Alpine Direct Fit Kit 23 | To finish off the connection of external options, the GPS antenna adapter is attached to the factory wiring. The other end of the GPS adapter is plugged into the Alpine radio, giving it Navigation and other functions that rely on global positioning technology.
Photo 25/36 | Alpine Direct Fit Kit 24 | Alpine’s full iLX-F309FRN setup is connected and ready for installation. The connections are checked one final time to make sure everything is snapped into place correctly.
Photo 26/36 | Alpine Direct Fit Kit 25 | The full Alpine radio assembly is lined up and the clips are snapped into the factory holes.
Photo 27/36 | Alpine Direct Fit Kit 26 | Using a driver and a 10mm socket, the crew bolts the bottom of the kit to the Toyota dash using two out of the four factory 10mm bolts.
Photo 28/36 | Alpine Direct Fit Kit 27 | Then, the HVAC panel is connected with the factory wire that was previously left inside the HVAC cavity on the dashboard. The 4Runner factory HVAC panel snaps into place below the new radio panel.
Photo 29/36 | Alpine Direct Fit Kit 28 | The side bezels that were first removed to start this process are now snapped back to their original place, completing the install.
Photo 30/36 | Alpine Direct Fit Kit 29 | The ignition is turned on to confirm the radio comes on and make sure the HVAC controls function correctly.
Photo 31/36 | Alpine Direct Fit Kit 30 | After the radio initializes, the crew starts to scroll through the customizable gauge and tire pressure screens.
Photo 32/36 | Alpine Direct Fit Kit 31 | The 4Runner is turned on and shifted into reverse to check the backup camera functionality.
Photo 33/36 | Alpine Direct Fit Kit 32 | The HALO9 has a built-in parametric equalizer, giving each user individual adjustments for sound quality.
Photo 34/36 | Alpine Direct Fit Kit 33 | There are also sound curve presets for popular music types if you’re not into messing with adjustments manually. As if the HALO9 isn’t badass on its own, the Alpine crew threw a few more surprises into the 4Runner.
Photo 35/36 | Alpine Direct Fit Kit 34 | To complete the demo vehicle, a custom-installed 12-inch X-Series subwoofer resides in the cargo area on the passenger side.
Photo 36/36 | Alpine Direct Fit Kit 35 | On the driver side, a custom-installed set of X-Series amplifiers appears to float above the factory side panel, leaving plenty of room for cargo while supplying power to the doors and subwoofer.
