Step 4
That box is not present on cars with CDR24
it IS present on ASK and BOSE cars

if you have CDR , skip that step

 

No luck imma fraid

spliced in the unused yellow trigger wire to the PCM on the combined RCA/trigger wire included in the camera kit
hooked up the 12v to the camera via ciggie lighter
then hooked the trigger to the car + via ciggie lighter

Odly enough auto config, briefly showed Camera detected
but then it failed to show any image, nothing happened.

ran auto config a second time.. now it no longer found it.

suspected maybe the trigger wire in the RCA cable was bad.. so connected a test wire straight to the yellow wire
right to the 12 out of the ciggie lighter
still no go, no camera detected..

Have errands to run, and need to let it rest, i'm very impatient in such things.. If i try to long I'll get to frustrated and reach for my brute force fix tool, which is a hammer. And that won't help either

 

it just dawned on me.
could the trigger be an open connection to ground
eg instead of applying 12v, it needs ground?

or perhaps it only works when you power the camera off the pccm.. I'll have to test that seperately, but need to make a connector first

 

That is kind of what I figured, and what I did…which still doesn’t explain the lack of solid FM reception. Admittedly, I havent tried it outside of my shop so perhaps when the weather improves and I can pull it out that will be a better indicator.

 

That's the same method and scenario I'm getting. #1183
Also USB port doesn't highlight on media screen, or Android Auto the same.

 

I got more cables and stuff coming in for the USB and other stuff
once it all comes in i'll pull it out properly for a bit more testing

 

all needed is a confirmed 12v+ to pin6. Which will flip it to reverse camera mode (don’t need camera plugged in or powered)

was this done ?

 

Not sure if you're following exactly as myw stated, but as I follow he's saying he believes pin 6 is the trigger input (this is not the yellow wire on the factory harness) and when pin 6 is triggered (via reverse light blue/black wire) - power is then enabled on pin 8 which is where the camera should be powered.

 

ah, i thought yellow was factory trigger for tiptronic that went to 6
did not pull pccm out all the way this time, will do so when i get the rest of my stuff for the rear usb, on monday and pull it out properly, get all pins checked properly and do it all in 1 go

 

this one id have to respectfully disagree with - the 8" screen looks perfect in the spot. i am revising the design for the next iteration of my android pcm where i will use 20mm ***** while keeping the (max possible) 8" screen as is - there is more then enough room, and i had it designed that way to begin with. TBH, even 8" is pretty small for todays standards + 7" screens were available as oem since 2007.

Don't forget with the 2021+ AHD front + reverse cameras, the image looks like modern oem backup cams with the 720p HD screen. not a major deal but having used both - it looks alot more pleasing.

 

I could go to the same shop that figured it out and get the rear camera installed. I can watch how they do it and report back. I even bought the same camera from rydeenn and I’m in LA. I’m just not keen on paying money since I’m used to DIYing this kind of mod.

 

you should try hooking up the rear camera rca to a monitor or TV just to make sure the camera is outputting

 

already did that before trying it on the car, the camera is fine
just need the trigger

 

no need (at least not yet) - the main thing for the manual cars is to confirm the ability to flip the pccm+ into reverse camera input mode via the acceptable / acknowledgement of the 12v+ input in the reverse trigger pin. even if the screen turns black with the 'no video input detected' display then we are completely good.

based on the rest of the thread the fakra video input will work fine provided the harness isnt broken.

 

pin7 currently outputs 3.3v (confirmed) - based on the chart its a PARKING (gear) indicator. i suspect its useless for manual cars and will never change (unless the reverse trigger is activated) as there is no transControlUnit to indicate the car is in any gear.
