Unlocking the E9X backup camera!

He is saying that a member on that forum once asked a question, "Does the shifter show where reverse is?" or something to that effect.
oh lmao my bad slow moment there tought u were asking me about my screen shot I took of the camera working (actually from a video), i was like what is he talking about lmao, yeah I actually read some of those comments and man there are some characters there
Have you tried the electronic steering wheel with the DCT? I'm about to do that, what were the problems exactly?
Nope, however i plan on it. I would think it would be fairly simple but knowing BMW's complexity in their electrical system it wont.... Only thing i could see going wrong is the signal that the DCT outputs to the emulator may be different than the others. However if this works for both manual and auto, im almost positive it should work for the DCT since they're looking for the same signal since its just coming from the CAS and FRM module.
Also doesnt seem to bad an investment when i reverse park and not be paranoid about shoving my exhaust straight into a curb or stopper....

Yeah its nice. I also bought a front camera to mount in the grill, will make parking next to a curb much easier.
How are you planning to incorporate the front camera to the display? I assume only one camera can be displayed at a time unless we are able to incorporate a system similar to the f30 that does a full 360 view of the vehicle. You could use a hardwired or design your own controller switch i guess.
I don't use the same emulator as you, I use an aftermarket camera display. I had xcarlink before and it can do this, and so can Avin, which is what I have now.
I see, makes much more sense. Looks like a perfect system to integrate it. I look forward to seeing how it turns out for you.
I would think of doing something like this but at the same i want to keep the OEM look.
You can use the oem backup menus, there is just no need or reason to. You get dynamic backup lines with the aftermarket stuff also.
Great Thread.
I am considering the backup camera for my 2011 335i E93. I read as far as I could but I still have few questions :
- I have factory CIC ( C1A version) with front and rear PDC. Is emulator a must for me ?
- Most of the ebay camera links expired( sold out), so if anyone recently purchased one, please recommend or share the link.
- someone mentioned I must use the extension MOST harness- I did not understand that clearly as to whats the difference between tapping on to existing connectors vs using an extension ? I know extension would make my job easy.
Thanks in advance.

The emulator is required no matter what version CIC you have, as the hardware is not present in any E9X/E8X as far as I know. The emulator just activates some dormant software already in the CIC. The hardware is the missing portion. I'm pretty sure its an E60 thing and above and it comes in a much bulkier package that doesn't fit these cars and is certainly very expensive.
I had one from autofocustech, the camera went bad after some time, I'm not sure why. I bought a new one from technetronix and it has been holding up, at least so far.
You don't need to use the extension, but you'd be silly not to in my opinion. You have to splice onto these wires, you don't want to do that to your factory wiring if possible. Just buy the extension and go to town on it, you can buy a new one if you mess up or revert it back to stock later.
Thanks.
So I got the emulator (autofocustech china) and the harness as well. Camera I bought from amazon.
Hooked up as per the instructions and coded. I was impressed that just after installing and coding everything started working. Switched to reverse gear and instantly image came up- almost no lag.
But...if I switch to neutral after reverse gear, the camera remains on. Actually PDC remains activated. I have to manually deactivate the PDC by pressing the PDC button. I cant figure out why its happening.
The white wire from the emulator always outputs 12v. Is it supposed to do that ? Even if I remove the white wire ( from the camera), PDC doesn't return to off status once the reverse gear is disengaged.
Any idea ?
I figured out it's most likely the coding and not the emulator. I removed the can L and can H lines so that the emulator is not connected and not sending/receiving any signals from cic. And guess what, the PDC screen doesn't clear up when reverse is disengaged. If I drive, after 10-15mph, CIC forcefully clears up PDC. But at idle,, it doesn't.
I am not coding it differently than what others and you mentioned. So kind of lost now.

I do know that some backup cameras will leave the reverse camera on for a short while even when driving forward(few seconds). Sometimes you have to back up twice to get to where you want to go so it just keeps it in reverse mode I suppose. As for your situation, I cannot help since I didn't end up going the OEM route.
I did some troubleshooting today.
It's confirmed that the white wire constantly sends 12V even if the reverse gear is disengaged . But when I removed the emulator, I noticed my regular PDC interface also gets stuck the same way ( does not switch off once reverse gear is disengaged). So not sure if its the emulator or some bad coding. I removed the $3AG and reset all the modules but no luck. I reverted to the stock coding but same thing. Only one thing that I didn't do was even remove the wire tapping but not sure how that's going to impact as the emulator box itself was removed.
So at this moment I am totally clueless as to where the problem is. Somehow CIC is not sensing that reverse gear is disengaged it seems.
I wonder if there was an error in the coding somehow? I wonder if this is default behavior in a 6MT?
