Tundra Front Camera: Add a Second Camera Input Too
A Tundra front camera solves a problem every owner of a new full size truck runs into within the first week. The hood is tall, the nose is long, and a parking block you can clearly see from outside the truck disappears completely from the driver seat. We installed the Beat-Sonic CS15A front camera interface with a BCAM13 camera on a 2026 Toyota Tundra, and the part most owners miss is that the same interface has room for a second camera.
The CS15A puts a front camera view on your factory Tundra screen through an OE look button that drops into a blank switch. It also carries a second RCA video input, so one interface can run a front camera plus a trailer, undercarriage, or blind spot camera on the same button.
Fitment First: Which Tundra Screen Do You Have
The CS15A covers the 2022 to 2026 Toyota Tundra with the 8 inch display screen only. If your truck came with the larger screen, this is not your part. We do not currently offer a front camera solution for the larger Toyota screen, and we would rather tell you that up front than have you order something that will not fit. If you have that screen and want to hear the moment something exists for it, email info@beatsonicusa.com and we will add you to the notify list. Confirm your screen size before ordering, because the two dash layouts look similar in photos and are not interchangeable electrically.
The camera in this install is the BCAM13, a universal front unit with a 160 degree fisheye lens and an IP67 rating, mounted behind the grille. You can browse the rest of our camera solutions if you are covering more than one angle on the truck.
Wiring the Interface Behind the Radio
Nothing gets cut and nothing gets spliced into the factory harness. The whole interface sits between two plugs you already have.
Getting to the Connectors
Lift the top tray out of the dash by hand. Press the release tab on the cigarette lighter plug and pull it free. Behind that tray you will find the harness bundle. Two plugs matter here. Connector A is the one closest to the passenger side, and connector B sits in the center. There is also a small green single pin plug you may need to move out of the way, and it is easy to lose track of, so reconnect it before you close anything up.
Making the Connections
Unplug A and B, plug the CS15A harness into each of them, then plug the harness male ends back into the radio. Listen for the click. Connector A in particular takes real force to seat fully, and a half seated plug is the most common reason a first start up shows no camera at all. If you would rather have room to work, four 10 mm bolts release the whole radio.
The Second Video Input
The interface provides two RCA camera inputs. The first is the front camera. The second is an optional input that most people leave unused, and it accepts any additional camera. The interface supplies power and ground to that camera through the same harness, so you do not have to run a separate power wire. The obvious use on a Tundra is a trailer camera, since your factory backup camera is looking at the front of the trailer once you are hitched. Owners also run it to an undercarriage camera for trail use, a blind spot camera, or a cabin camera aimed at a child seat. One interface, two views, no second button. The second input is off by default and has to be switched on in mode C, which is covered below.
Mounting the Switch and the Camera
The Switch
Pull the panel below the screen and find an unused blank next to the heater button. The blank pushes out from behind, so unclip the bottom edge and press it forward with a flat tool. The Beat-Sonic switch clips into that opening and reads as factory equipment. Insulate the two illumination wires separately if you are not using them. Even without the dash illumination feed the switch glows green, so you can still find it at night.
Routing
Run the switch cable from the top down rather than fighting gravity from the footwell up. A wire routing tool with a claw end makes this a two minute job instead of a twenty minute one. On the camera side, power and ground go through bullet connectors, red to red and black to black, and video runs on the RCA pair. Tape every joint. A front camera that drops out over a pothole is almost always an untaped bullet connector.
The Camera
The BCAM13 hangs from the top of the grille opening. We trimmed the two outer tabs off the bracket for more contact area. From there the harness follows the factory loom up to the hood latch, under the crash beam, past the ABS block, and into the cabin through the firewall grommet on the driver side. Have someone sit in the driver seat while you set the camera angle. Eyeballing a fisheye lens from outside the truck is how you end up with a picture that permanently leans right.
Working through the dash anyway? A lot of owners knock out a stereo upgrade in the same session, and our stereo interface and replacement kits use the same plug and play approach.
Programming the Modes
Out of the box, one press shows the front camera, a second press returns to the factory screen, and the view times out after 15 seconds. The settings live behind a press and hold sequence, and you pick one by watching the button light while you hold it with the truck starting up.
A slow red blink is mode A, the view timer. A slow green blink is mode B, automatic front camera activation. A rapid red blink is mode C, the second camera input. A rapid green blink is mode D, backup camera push to view. Let go on the mode you want, then press the button to set the value. One blink means off and two blinks means on. Press and hold again to save.
The Three Worth Knowing
Mode B brings the front camera up automatically at low speed. Beat-Sonic specifies under 9 mph, which is exactly when you are easing into a space and cannot see the curb.
Mode C switches on the second camera input. Leave it off and the second press just returns you to the factory screen. Turn it on and the second press shows whatever camera you wired to that input, which is the whole point of running a trailer or undercarriage camera in the first place.
Mode D enables backup camera push to view, which brings up the factory rear camera at any speed, including on the freeway. That is the setting that turns your factory backup camera into a live trailer check while you are moving.
Mode A lets you stretch the 15 second timer, shorten it to 5 or 10 seconds, or switch it off entirely so the view stays up until you dismiss it.
What It Looks Like Day to Day
Nothing about the truck reads as modified. The dash is factory, the screen is factory, and the only visible change is one more button in a slot that used to be a blank. Press it and you get a wide view of the pavement ahead with a clear line showing where your bumper actually ends. Pulling nose in at a supermarket stops being a guess, and you stop reversing into every space out of caution.

Common Questions
Does the CS15A fit every Toyota Tundra?
It covers 2022 to 2026 Tundra models with the 8 inch display screen only. We do not currently offer a front camera solution for the larger Toyota screen. If that is the screen you have, email info@beatsonicusa.com and we will add you to the notify list.
Can I run two cameras on one interface?
Yes. The CS15A provides two RCA camera inputs. The second is an optional input for any additional camera, which owners commonly use for a trailer, undercarriage, or blind spot camera. Switch it on in mode C and an additional press of the button cycles to that camera.
Will the front camera come on by itself?
It can. Enable mode B and the front camera activates automatically at low speed. Beat-Sonic specifies under 9 mph.
Can I see the backup camera while driving?
Yes, once push to view is enabled in mode D. The button then brings up the rear camera at any speed, which is useful for checking a trailer on the road.
Is the camera safe in rain and car washes?
The BCAM13 carries an IP67 rating, so weather and road spray at the grille are not a concern.
Does anything need to be cut or spliced?
No factory wiring is cut. The interface plugs in between two existing connectors behind the radio, and the switch drops into an unused blank in the dash.
