Sangria, thank you very much for your detailed write up for this retrofit.

I retrofitted the camera on my e92 m3 and all worked really good.

Based on the pictures I believe the e92 has more room in the trunk for the cable connector.

The parking aid lines came after the calibration with inpa and a short drive.

I used:
e70 TRSVC
cable harness from the ebay seller
chinese ebay backup camera for e90
f25 oem backup camera (modified to fit on the chinese camera handle)
x1 pdc
JBE "M" version
Where did u install trsvc module?

Ok install jbe m today and I'm still having the same issue, Pdc is not communicating with car with i borrow power and can h/l from it to power tr module. Is it a possibility that Pdc can't supply power or can h/l for tr module?
Maybe the fuse is blown for PDC? While you grab power for TRSVC.
Before I installed all correctly, for testing I grab power from Combox and can from PDC.
When you disconnect the TRSVC, the PDC is working?

Yes when i unplugged trsvc and return oem wires to pdc. Pdc works as it should. I just ordered oem wiring harness to see if that fixes the issue if it doesn't then I'll be stuck. This last time when. I connected the wires and scanned with ista p it showed up yellow and not red so i made progress. The code i got was a k can. Oh btw the doesn't recognize trsvc at all it doesn't show up in ista or inpaw

Congrat buddy. Thats why i am here and thats why i share here! Made my day!

And you are right bout the space. E93 is tight. E90 was alot better. e92 is the best i guess :)

Did you properly VIN flash the JBE3 and default code for your car?

I updated jbe with winkfp and default code jbe not the whole car

No not the whole car. Just the JBE. Well can you communicate all the other modules except the TRSVC?

If you can not communicate with the TRSVC check the Software No. If it starts with Numbers then it belongs to F series and i also had one and does not work for our cars! If it starts with Letter (A,B,D) that belongs to E series which is fine. LMK!

Wrong part. That belongs to F series and F series uses 500kb vs E series uses 100kb on KDCAN. Just like the F series CIC cant fit on E series! So i warned couple of Ebay sellers who put a title like X1 E9X on a F series TRSVC but cant correct everyone. You need to get E series!

+ I tried to Expert Flash the TRSVC with X1 files using the winkfp But since i couldnt communicate , i couldnt flash it.

Send me the VIN no. Let's see what E series X6 came from! All E70/E71 TRSVCs came with Side View or Top view options there is No single Fakra E70/E71 TRSVC in the states!

That sounds right. Got a link to any reasonable one
You can get this one. You will see top view camera error on ISTA but will work without an issue. Later on you can activate the top view , if you find the camera with harness!

I might just take you up on that offer!

Where did u install trsvc module?
hey there, I installed the trsv below the combox/media bracket with a nut and secure it with a zip tie.

I don't have more pictures of the oem camera and the chinese handle, but I had to dremel a lot of the inside where the chinese camera was to make room for the bulky oem camera.

The end result looked very similar to Sangria's camera fitment.
That's about right. Great job!
