Is it possible to tie the USB cable into the factory location? If I have to plug my phone in for carplay functionality, I don't want to be opening the glove box every time.

It should be possible but I haven't done it myself. Go on aliexpress.com and search for "BMW USB adapter". Something like this:

https://www.aliexpress.com/item/USB-...906995407.html

Pull out the USB/Aux jack from your car and check if that green Fakra plug looks like it will fit and is the correct male/female. But if you get that cable you'll also need a USB-A male to USB-A male adapter or cable to connect it to the Joying unit.

I saw this: https://www.aliexpress.com/item/USB-...804175657.html

which has a USB-A male plug, and you can buy it without the port panel for $6.99 + $2.41 shipping, but it's for a VW so I'm not sure if the green Fakra plug is wired the same as BMWs.

However, when the engine is running I get wavy interference in the video. So I ordered a PAC CSS12 noise filter and will see if that helps.
UPDATE: I installed the noise filter but I also improved the ground by connecting the bolt next to the tail light to the main battery grounding point. There's no more interference but I'm not sure if the noise filter or grounding helped more.
Stubbie: BMW is using some sort of AC signal riding on the DC. A simple rectifier was all that was needed. I found one on Amazon for $10 and it solved the problem. You don't need a switching relay. click here

That's good to know. I don't really know much about electronics but perhaps the PAC CSS12 noise filter that I used also does the job of a rectifier?

Did a DIY walk through on my camera install for my 2012 135i convertible E88 but it may help others wanting a camera with out costing a lot and involving a lot of complicated install labor.
See it here

SO MUCH APPRECIATION TO THE PO! Stubbieblue has been incredible, answering my noobie emails and questions night and day

(if you are super noob like me you may have questions)

THANKS STUBBIE! IM 100%....

P.S - I will bother you one last time for programming, i got my steering wheel working and bluetooth set up but any reccomendations for maps to work? Apps? carplay? etc Or tell me how you set up yours and ill mimic it
Hi James,

I was wondering what happened when it failed? I had the whole thing working well doing just a 'dry fit'. But then when did the actual install and ran the car, I was getting static, and now when I put the car in reverse, all I get is a black screen with the yellow guide marks. Was that how it failed on yours? I'm just trying to narrow down if it's the camera, the wiring, or something else. Thanks

Wiring for filter

Hi Stubbie,

Your thread was invaluable to doing the deed. Wasn't easy, but the Joying unit is nice. One question though: The rear back up camera worked fine until the car was running. I ordered the filter you suggested but I'm not sure how to wire it in. Is there any chance you could show/sketch how this is integrated into the wiring? Thank you. You've done some great work for the BMW community.

Sure I updated the original post to show how the PAC CSS12 is wired in.

But apparently, according to doane2u, you just need a rectifier and don't even need a relay.

By the way, jamespaoli did PM me with the same problem like you: black screen with only guide marks in reverse with car running.

You have to disconnect the backup cam red wire from the relay (yellow wire on mine) and insert the PAC CSS12 in between them.

The PAC CSS12 has 3 wires:
The red input wire connects to the 87 yellow wire from the relay
The blue filtered output wire connects to the red backup cam wire
The black wire connects to the grounding point

I also used a wire to connect the grounding bolt next to the lights to the main grounding point below that the battery negative is also connected to.

I pointed that out in several threads and the DIY install I linked to above. With the German cars you are going to need an isolation unit between the power and your camera. You can do this by using a relay, but a much easier way is to use a rectifier that blocks the BMW signal riding on the DC that is causing the static and black screen.
The one I used is the Dasaita 12V DC Power Relay Capacitor Filter Rectifier that sells on Amazon for about $10 with shipping.

You just wire it in between the camera plus and negative and the cars reverse plus wire and the negative ground wire.... very easy. If you are getting separate power for the front screen from power there, you will probably need to do the same thing.

Hey sorry guys i have been very busy with work and now dealing with my car needing a jump to start...

Lowerfredrick: My issue was when going into reverse the screen would trigger to the reverse cam with the yellow lines/black screen, would never turn on video.. I triple checked all my wiring and made sure it was EXACTLY the way stubbie has shown.

I replaced my camera 2 or 3 times, and re-wired/replaced my relay as well. I performed the test that stubbie also says where you can use the camera in wire directly to the back of the unit.

My issue was solved overall being a faulty camera, i did also connect the 2 previous cameras and use it on a TV and it still didnt show video, confirming the 2 previous cameras were dead.

I would triple check your wiring, try your camera on a TV or using the camera-in port on the headunit... If you have a volt meter you can test the power wire to the camera to see if it is getting voltage too...

Hey replying again, if it worked while doing a dry fit i wonder when you snaked the cable from inside the trunk to the reverse camera if you teared/frayed? I would test the power cable for the camera from the relay and possible put a tap on the power wire above the relay(near the camera)and test it there too
