2020-2024 Toyota 4Runner Upgrade Guide: Cameras, Audio, Throttle

The 2020-2024 Toyota 4Runner upgrades in this guide all work with the equipment your truck already has, because these are the final years of the 5th gen 4Runner and owners plan to keep them for decades. Toyota never gave this truck a modern stereo, the hood still hides a small parking lot in front of the bumper, and the pedal takes a beat to answer. We can fix all three without cutting a single wire, and every piece comes back out without a trace.

Add a 4Runner front camera to the factory screen with the CS10B

Park a late 5th gen 4Runner nose in anywhere and you will feel the problem. The hood sits high and flat, so curb stops, planters, drive-through curbs, and anything below about waist height vanish long before your bumper reaches them. At the trailhead the same blind zone swallows the rock you were trying to straddle. Owners learn to guess, and scraped valances prove how well that works.

The CS10B front camera interface replaces the guesswork with an actual picture, and it is the upgrade we recommend before anything else on this truck. It is built for 2018-2024 Toyota models and puts a live front camera image on the display your 4Runner shipped with. No added monitor, no replacement head unit.

You get two ways to use it. The first is on demand: press the included switch when you want the front view, check your clearance, and return to your normal screen. The second is automatic: the CS10B can be programmed to turn the front camera on by itself at parking lot speeds, so the image appears while you creep toward a parking block and clears once you are moving again. Many owners run it both ways, automatic in tight lots and on demand at the trailhead.

The install is more approachable than it sounds. The interface module connects behind the factory radio, the camera mounts low on the front of the truck, and a cable runs between the two. Nothing in the factory harness gets cut. Pair the interface with the BCAM13 wide angle front camera or the BCAM11B. The two are interchangeable fisheye cameras that show the full width of the front end in one view, corners included.

Be clear about what the camera does not do. It is not a parking sensor, so there is no beep and no distance readout, just an honest picture. It does not record like a dash cam, and it needs a working factory screen, since the interface adds a video source rather than repairing a failing display. Browse our front cameras collection for more options, and confirm your screen on the CS10B product page before you order.

One 4Runner amplifier platform covers every 2020-2024 truck, JBL or not

The factory audio in these trucks is polite at best. Turn it up on the freeway and the sound gets louder without getting better. Speakers are only part of that story. The head unit sends a low powered signal, so a 4Runner speaker swap alone rarely delivers what people expect, and even the optional JBL system runs out of headroom once road noise climbs. The real bottleneck is clean power, and that is what an amplifier fixes.

Our headline pick is the ENA-3T3, the highest powered plug and play amplifier kit we make. It fits the entire 2020-2024 4Runner range, JBL and non JBL alike, so you do not need to decode your audio package before ordering. It connects between the factory head unit and the speakers with OEM style connectors and includes dedicated RCA outputs for a powered subwoofer later. If bass is not in your plans, the ENA-2T3 is the same full range fitment without the subwoofer outputs.

What changes after the install is the part owners talk about. Vocals separate from the mix instead of blending into it, volume you used to avoid becomes volume you use, and the system finally keeps up with all terrain tires at 70 mph. Your screen, steering wheel controls, and factory features all stay, because the kit amplifies the factory signal rather than replacing anything.

2020-2021 trucks have a second option

If you drive a 2020 or 2021, you can also use the ENA-3T1 with a subwoofer output or the ENA-2T1 without it. These come from our 1987-2021 Toyota, Scion and Subaru family, and they work with JBL vehicles as well as standard audio. Between the two families it is a genuine coin flip on sound. The practical difference shows up if you have JBL and want a subwoofer, which we cover next. Confirm your exact year on either product page, or run your truck through the parts finder on the Beat-Sonic homepage.

Adding a subwoofer, including on JBL trucks

The ENA-3T3 route is the simplest. Its RCA outputs feed any powered subwoofer, and the kit includes a remote turn-on lead so the sub wakes and sleeps with the ignition. On a non JBL truck the sub follows your factory volume knob naturally. On a JBL truck that RCA feed plays at a set level, so you adjust the sub with its own bass knob.

If you have JBL and want the sub to track the factory volume knob, pair the ENA-2T3 with the ACS-T02 powered subwoofer controller, which is built for Toyota JBL systems and adds volume synced outputs. One planning note: the ACS-T02 pairs with the T3 kits only, so a JBL owner with subwoofer ambitions should pick the ENA-2T3 or ENA-3T3 rather than the T1 family. For an under seat sub, our EAZ-C02 power seat harness supplies clean power from the power seat connector, no cable through the firewall.

Here is what these kits do not do. The Encore Alpha series has no DSP and no app tuning; it is straightforward clean amplification, which is exactly what this truck needs. The amp also enhances a working factory system rather than replacing it, so a failing head unit or dead factory amplifier needs repair first. Every amplifier kit carries a 2 year warranty.

ShiftPower SP26: a 4Runner throttle controller without the hype

The drive by wire pedal in the 4Runner is tuned soft, so there is a noticeable pause between your foot and the engine. You notice it most rolling into a gap in traffic, where the truck pauses before it answers. The ShiftPower SP26 covers Toyota and Lexus models including the 2014-2024 4Runner, and it changes that pedal mapping. It plugs in at the accelerator pedal connector in minutes, with no change to the engine itself.

Here is the honest version. A 4Runner throttle controller adds zero engine power. What the SP26 changes is how quickly the throttle delivers the power you already have. Sport style modes make the truck feel awake around town and confident when merging. Eco mode goes the other direction and softens the mapping, which helps improve fuel economy for many drivers by smoothing out heavy footed inputs. Softer settings also make low speed crawling easier to modulate on the trail. The SP26 carries a 3 year warranty, unplugs to stock in the same few minutes it took to install, and the whole range is in our ShiftPower collection.

Sound deadening: the cheap multiplier

A body on frame SUV on all terrain tires generates a lot of road noise, and that noise eats audio quality at any volume. Sound deadening material on the doors and floor is the least glamorous item on this page and one of the best returns per dollar we sell.

The material adds mass to thin panels, which cuts resonance and road roar. The factory system sounds fuller, an amplified system sounds dramatically better, and doors close with a solid thunk instead of a clang. Find the material in our sound deadening collection. The smart part is timing: if a door panel is already off for a camera or amplifier install, deadening that door adds minutes, not hours.

Where to start: the order we would do it

After years of these trucks in our bays, here is how we would sequence it. Start with the front camera if the 4Runner is your daily, because it changes every parking maneuver from day one. Start with the ENA-3T3 if audio is what bothers you most; it is the upgrade owners tell us they should have done years earlier.

Either way, book the camera and the amplifier together. Both connect behind the dash, so one appointment covers both and the trim only comes off once. Have deadening done in the same visit while the doors are open. The SP26 is the easy add at any point; it installs at the pedal in minutes. Nearly every product here has an install video on our YouTube channel, so you can preview the whole job before committing a weekend.
