So I was hooping there were some parameters for camera power shutoff delay and reversing camera "post-roll".

If I was super-ambitious (I'm not), a diode and a capacitor could solve the 2nd problem.

One can dream!

You may be able to do this: if your front camera is unused, you can connect the front camera signal cable from the MMI to the rear camera signal cable and enable the front camera timer for up to 15 sec or less in the menu. This way after the gear goes from R back to D (and possibly into N) the rear cam will still get a signal for that period of time. This would only work if the MMI senses going out of R vs. going into D. The manual (see below) seems to indicate the going into D from R or from P will enable the front cam signal line for the selected number of seconds. So may not work when coasting in N after R.

But you can also setup where if you switch into R, the rear cam signal stays in a HIGH state with a relay or timer holding it until the MMI detects you switching into D (i.e. the front cam gets engaged). And that would break the timer/HIGH signal going to the rear cam signal cable.

Have you selected the right pins (2,3 & 5 ON)?

I used the reference stating 1 and 2 on as seen in pic. I just tried 2,3 and 5 but that didn’t work (wouldn’t even display CarPlay)

Okay, I just have 2 and 3 set to ON, not 1, only difference between our systems should be the screensize (6.5 vs 8.8"). Try setting 1 to off, remember to restart the unit by holding in back.

Edit:
The reference I have is from this threads first page. Your unit is for EVO not NBT.

May want to try to Enable/Disable Carplay U/D key as well. Reboot and try.

Do your steering wheel keys work?

My steering wheel controls work (volume and scroll wheel). However I do not have a CarPlay U/D option to toggle

Tried this and same result as original (CarPlay boots and displays then display shuts off). Thank you for the continued help!
I’ve emailed tech support the issue including the video, we’ll see what they reply with

When you push the BACK button on the controller are you able to switch back and forth between the MMI and the OEM display view?

Also, your VOICE command button on your steering wheel should activate Siri while in MMI view mode if pressed 3 sec.

The Menu button and the number 8 preset do the same. This is the only way I can get the CarPlay to come back momentarily before it kills the display again. I haven’t tried the voice command, why do you ask?

There seems to be an issue with the MMI reading some of the CAN-bus signals.
May want to map out what works vs does not to narrow down the problem if it's a setting issue vs a corrupt firmware.

Try Carplay via USB and see if it does the same.

Before firmware reinstall, could try to remove BT pairing from OEM HU and also from MMI. And setup from scratch.

Gotcha, all functions work (including Siri) and same result when CarPlay via usb and after removing and retrying BT pairing.

Does the mmi automatically switch to the factory rear view camera when you shift into reverse? Or do you have to manually exit out of the mmi menu?

What is the right wiring for the front camera? I've just fitted one a few days ago but I had to wire it as if It were the rear camera because it was the only way I found where It switched on after the rear camera switches off. I'd like It to power on as soon as I selected D in the gearstick. I Wired positive to camera acc+ (yellow), negative to ground (Black) and trigger wire (placed near to RCA) to the rear camera cable (Blue wire in mmi I think)

I haven't wired for front camera yet, but for rear view I only wired the red wire on the RCA cable to 12v yellow wire (backup/rearview 12v), didn't wire ground or trigger and it works fine for my automatic transmission.

For front camera my plan is to wire the red wire on the RCA cable to 12v ACC, nothing else. They is what I've read should be work.

I mean, as long as it works for you, no need to fix it

Awesome that is great to know, and this is the factory camera right? Does it also switch back to mmi as soon as you are out of reverse?

Also I have a few other questions if you do not mind:

1) how do radio controls work - does it work while the mmi is still engaged?

2) Can you skip songs while in apple car play or android auto with the radio or steering wheel buttons?

3) Do the steering wheel scroll wheels work on the mmi? Or is it soley just the idrive wheel now?

Thanks

I'll try this option but how can it work without ground wire? I Don't Know if the problem is that my rear camera is OEM and it shows image always before the after market front camera

The RCA plug also has ground. I don't know how it works with OEM camera, but maybe try that and select how long the front camera should be engaged for after reverse in MMI settings.

12V ACC what's ACC means? Accumulator?

You need to use the cable and 12V internal switched by can bus wire from MMI box. The MMI box switches between the 2 cams. Both 12V wires are marked. One for rear 12V other for front cam supply. I've made a Youtube movie so you can see the automatic switching between the two cams while driving the car. Check the thread if you like to see it. Have fun.

1) yes, car automatically switches between oem rear view cam as it should
2) yes, all controls still function outside for the MMI
3) all controls work outside of MMI and momentarily work within CarPlay until it freezes and then kills the display
4) steering wheel controls work momentarily in CarPlay until it freezes and the display dies

I've used the wires from mmi as I wrote in my first post, yellow for supply and I used rear supply too connected to the trigger, the one nearest to RCA from camera wiring because only with the yellow wire the camera was always on Although I set 7 secs in mmi menu.
I have other issue related to my mmi. Checked and it's Always the same, everytime the car is unlocked for a few minutes when I open a door a short circuit sounds through the speakers. I think that the mmi is powered on and when I open one of the doors the head unit wakes up and starts the Hi-Fi OEM amplifier which produce the srhriek sound

He has a problem on his system, maybe software, maybe hardware related. Everything works fine for most, I've haven't had any issues.

Yeah the chinese has no proper built mute circuit in it. It delays the smooth respons of the audio circuitry. So I think you have to live with it. Or build a delay with two transistors if you're a handyman.
