I bought a 360 system from bearbu a year ago and just now got around to installing it. It's on a 2016 Tesla S. This not my first wiring rodeo, but I am having a problem. The HDMI trigger signal works as per instructions, However, I get no images from the Surround View Monitoring System. No response from bearbu. Does anyone have a troubleshooting system/chart?
I'm going through something similar. Maybe we can compare notes.
I've had the system for almost 2 years. Overall it worked fairly well (although my front camera failed). Mine is on a '17 MS with the Infotainment upgrade.
Just finished a 3600 mile road trip. Once on the trip, the camera screen turned all white and I could not switch back to the OEM camera. Once stopped, I rebooted using the "switch tire size" method (wait for reboot, change back). Since it's powered by the CAN connector, I believe that method interrupts that power forcing a reboot of the 360-degree system. Things went back to normal.
Almost nearly home the problem recurred. The above approach failed, I have a white screen, and cannot switch to the OEM camera.
Took it apart once I got home. I could hear the HDMI box "click" when I press/hold lower right steering wheel button - so it appeared to be switching the video source.
Realized a bit more how this works. Tesla uses cable-like connectors for MCU video. The 360 HDMI box intercepts that cable, plus it has an HDMI input. So it should be able to route the OEM cable signal, or switch and send the HDMI signal out instead. This box also has the CAN Bus connector. So it has video in, video out, HDMI in, and CAN in.
In my case, again it appeared the 360 HDMI box was attempting to switch inputs. I also have an HDMI cable where I can mirror my phone to HDMI and I plugged this into the HDMI box directly - no joy.
My conclusion is that my 360 HDMI box has failed. Also tried to get BearBu without success. I do have his phone # and we have communicated via WharsApp in the past, but no joy this time. Honestly I was hoping to find a 360-degree box on here someone wanted to get rid of.
Considering zero parts/support, not sure I'd do this again. The features I used regularly was the front bumper cam and HDMI to mirror my phone. I ended up just taking the HDMI box out of the online config so it's essentially back to OEM, but all of the parts are still there and could easily be reconnected.
What does your screen look like? Can you hear the HDMI box click? Can you go back to OEM via the steering wheel button? Try plugging a known good HDMI input directly to the HDMI box? Maybe reboot using the tire size method?
BTW, I also discovered you need at least a regular steering wheel reboot if you change ANY video settings/cables, or it's not recognized.
