I found one and ordered it.. I’ll let you guys know how well it works.. If nothing else, at least I have the camera part of the system..

Any update on your findings? Did it work?

Any update on your findings? Did it work?

No because what was described as the camera system was just a power adapter. Found the system for about $900 from dealer but don’t want to buy that until know it will work and whether dealers can potentially install the other 2 fins. Seems like dealers have no idea and trying to talk to Toyota engineers is like talking to the wall. The response I got from them at Overland East about the small gas tank was frivolous. They have no idea what the real mpg is nor the range. They probably all drive a Prius and small gas tank is NBD. End of rant!

Tks for the update, but that sucks. Let us know if you find anything else out.

Do you have the PN for the camera?

@Gurvy522 if you still want to play around, here's where you can look for the trailer ECU (pulled from service manual):

?? Just need this box? No antenna? I found price around $400 for Telematics box. I am assuming the rest of the speaker box and seat belt assy is not needed.

Thanks, Interesting info.

Antennas would still be needed. Not sure about whether associated wiring harness is already in the truck as well.

Curious as to where you found the telematics box (and associated full part number)? I was having a rough time finding it.

bought a copy of the factory service manual.
and supporting your statements that the antennas and wiring are separate. It has those diagrams as well.

Some fun additionals for you Gurvy (if you confirm the module is behind the seat and buy a camera) - here are the troubleshooting steps for seeing the camera

Wireless camera image is not displayed when the AUX menu icon is pressed.

Confirm that 12 V power is being supplied to the wireless camera or that the internal battery is more than 30 % charged​

Confirm that the wireless camera is paired with the trailer camera ECU (communication telematics box)​

Confirm that the audio and visual system is operating correctly.​

Confirm that the panoramic view monitor system is operating correctly.​

Proceed to "Trailer Camera Image is not Displayed or Blinking Intermittently"​

DESCRIPTION

The display signal from the wireless camera is transmitted to the display.

WIRING DIAGRAM
CAUTION / NOTICE / HINT

HINT:

• Perform pairing after replacing or removing and installing the wireless camera.

• Inspect the fuse for circuits related to this system before performing the following procedure.
• Inner rear view mirror may flicker if wireless connection is poor. Due to inherit wireless limitation (out of performance range or scope) .

PROCEDURE

1.​	CHECK TRAILER CAMERA SYSTEM (CURRENT SIGNAL STRENGTH)

(a) Ensure the trailer camera system is tested without obstacles blocking line of sight or strong nearby Wi-Fi interference.


(b) Navigate to AUX menu screen on the multi-display and enter the diagnostic menu.


(c) Locate wireless signal strength menu parameter and take note of current signal strength when camera is 914.5 cm (30.00 ft.) behind the rear of the vehicle.


(d) Check the flicker condition is present when the wireless camera is 30 feet behind rear of vehicle.


OK:


Flicker does not occurs.

OK

​

END (TRAILER CAMERA SYSTEM IS WORKING WITHIN THE DESIGNED PERFORMANCE SCOPE)

NG​ ​

2.​	CHECK TRAILER CAMERA SYSTEM (CURRENT SIGNAL STRENGTH)

(a) Bring the wireless camera closer to vehicle rear until flickering stops or signal strength improves.


(b) Move back away from vehicle rear until flicker or signal strength is equal to the original recorded value.


(c) Check the distance from the telephone antenna assembly is 914.5 cm (30.00 ft.) or more.


OK:


The distance from the telephone antenna is 914.5 cm (30.00 ft.) or more.

OK

​

Curious as to where you found the telematics box (and associated full part number)? I was having a rough time finding it.

Found a couple different ones. All about the same price. Tried to narrow down using search with specific vehicle and no luck.

Only one antenna I see? I thought it added 2? I am seeing about $300 for the antenna.
