Why Upgrade the 4Runner Head Unit?

We all know the factory head unit has a lot to be desired. One of the main features includes Apple Car Play and Android Auto. So much so that the new 2020 stock 4Runners are shipping out with integrated Apple Car Play factory head units.

To bring my 4Runner up to speed with this current trend, I chose to install the Alpine Halo9 iLX-F309FRN. Although being one of the priciest of options, it’s one that comes fully plug and play, with no splicing, adapting, or extra wiring to adapt to the factory harness.

Carefully pull away driver and passenger side trim pieces below the head unit. Then pull away from the climate control. You can see this done in quite a few places on Trail4R.com but here is a good one.

STEP 7. Connecting the Harness

STEP 9. Install the Halo9

Return all removed components to their factory locations, push the harness back into the cavity, and install the Halo9 into the factory location.

Initial Impressions

The Alpine Halo9 is HUGE! It dwarfs the factory head unit display. Surprisingly, it actually fits the design and style of the 4Runner’s interior.

In the beginning, I thought having a floating display would not mesh with the factory styling, but as floating screens are becoming more and more common in newer vehicles, I found it easy to get accustomed to. The screen appears to sit up high, partially intersecting the above vents, however, it has no real large effects on blocking air to the driver or passenger.

User Interface

The user interface is easy to use and navigate through.

One of the concerns I had about the unit was start-up times. The Alpine Halo9 takes about the same amount of time to boot and pair with my phone in about the same time as the factory head unit.

I haven’t felt like I have needed to wait for my phone to connect to the Bluetooth or via USB for the Apple Car Play, before or during driving.

It all works very seamlessly and it is nice to have an advanced piece of tech in the outdated 4Runner for once.

The buttons on the screen don’t have any feedback, they are touch-sensitive. I was a little worried about having a touch button for volume and such, but they are performing just as well as a true clicky button.

While driving, the larger screen is easy to navigate through, bouncing through the car play menus, running Spotify, directions, pulling up messages, all a breeze.

Previously, my phone was mounted up high in the line of sight for all of this, after running this head unit I found myself off my phone less while driving and letting the car play unit do all the work.

Final Thoughts

Alpine Halo9 iLX-F309FRN Step-By-Step Install and Review For the 5th Gen 4Runner: Final Thoughts

It doesn’t take too much to outshine the factory head unit but the Halo9 does it in a big way.

Streaming songs via USB with the factory head unit, I would run into issues with “buffering” when skipping songs in rapid succession, and the Halo9 blows through songs with ease.

One of the small little features that I really enjoyed is that there is a small strip on the bottom of the unit that adds a soft illumination to the center console area.

With the Maestro harness, the Halo9 is able to pull information from the vehicle into a gauge cluster to display a tachometer, speedometer, etc. But most importantly, it can display tire pressures! When airing up, or down, you could relax in your vehicle, and keep an eye on your pressures.

After about a week of use, I had only about two real gripes with the aftermarket unit. The large 9-inch screen fits is at home in the prehistoric platform of the 4Runner. However, driving at night the screen can at times feel a little too bright. While it has a good amount of adjustability, I wish it had a little more. I prefer driving with a nearly dark cabin, and that can be hard to ask for with such a large screen.

Connecting To OEM Audio+ Reference 500 Series

While it is a direct plug and play unit to the factory harness, I am currently running an OEM Audio+ Reference 500 series. Plugging into the factory harness worked great, putting out more power than the factory head unit, but didn’t sound too good when connecting to my OEM Audio+ system, negating the need for all the corrective settings the OEM Audio sound processor is doing. I spent a lot of time adjusting the EQ and settings on the Alpine head unit to get it close to how it sounded before, but I couldn’t get it just right.

I want to give a shout out to OEM Audio+ who reached out to me offering to help reflash their sound processor, so I wouldn’t have to fight it to bring it back to the way it sounded before. OEM Audio+ has some of the best customer service we have experienced.

These two small qualms aside, I really enjoy how simple, and minimalistic the Alpine head unit is. Apple Car play is such a joy to use while driving and makes simple tasks like selecting new songs or playlists easy while driving.

The Halo9 is a HUGE step up and feels right at home in the as a new command center for the 4Runner.

In the end, as much as I loved those features, the plug and play installation, the lack of adjustability in the screen brightness was a deal-breaker.

I have then switched back to the factory head unit, and if I were to do this again, I would probably go with a smaller screen.
