Hey Stubbie-
After a disastrous experience with the Xtrons unit - it cooked itself once properly wired - I'm going to follow in your footsteps. I got the Joying unit and it looks like a quality piece of equipment. I'm just waiting for the Metra din plate to come in so I can install. One question - did you relocate your OE headunit or leave it out? If you removed it entirely, did you end up with the SOS error message in the OBC? Further, if you had that issue were you able to code it out? Thanks!

Stubbie, can you help me with steering wheel programming? I have the RadioPro set to Pioneer/Other, and I am in the steering wheel controls menu but it doesn't seem to be recognizing the steering wheel inputs. Above each column of buttons are little numerical displays that show 255 and intermittently change to 254. Wondering if I have a loose wire? But I can't find programming instructions.

Leave the RadioPro on the default Pioneer programming in the beginning to test it, and you can customize it later. When you press a button on the steering wheel the red light on the RadioPro should come on. Then on the Joying SWC screen, some of the numbers should change to like 50 or something, and you can assign it to a function while still holding down the button. If that doesn't work, check the wire (blue/yellow from RadioPro to brown wire of Joying) or try restarting the Joying headunit (swipe down from top and the middle icon I think). |

Bumping again and giving more props to Stubbie on this one - thanks for your suggestion! I had it wired right but I think the RadioPRO just needed a reset. Did that and was able to program steering wheel function immediately!
Now, a new issue. External bluetooth microphone stopped working. Figured I pinched the wire somewhere when installing. Removed it only to find that not only does it look fine but a replacement microphone also does not work. Internal microphone works as long as the external is disconnected but callers tell me they hear a lot of echo. Any ideas?

https://www.joyingauto.com/blog/post...oid-head-unit/ A different mic probably won't work because Joying uses a 4 pole plug (Tip Ring Ring Sleeve) with the mic probably wired on the 2nd ring and sleeve, while a standard mic uses the tip and the sleeve with no rings on the plug. I actually don't use the Bluetooth much because even with the external mic, callers still say they have trouble hearing me, especially with road noise. |

I found a thread on xda-developers at some point about changing the bluetooth audio codec setting and it making a marked improvement. Can't find the thread again but I may play around with it when I have some time and see if I can make progress. Worst case scenario I can get a stand-alone bluetooth handsfree setup I suppose - everything else works pretty damn well.

Thank you so much for your exquisitely detailed post. My son and I could never have done this (would never have done this) without your post. Not easy but it's done.
My question is about the back up camera. Everything was working well in the garage, even with engine running. Once we got all the trunk trim pieces in and everything buttoned up, we got static on the display trying to back car out. Weird. Why? Anyway, I ordered the filter you suggested. Can you please show, or explain, how this gets wired in? It's the last piece of a long puzzle. Thank you. Thank you. Thank you. |

You have to disconnect the backup cam red wire from the relay and insert the PAC CSS12 in between them. It 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. |

Thank you for the great guide! I followed it to the T but unfortunately do not get any sound. I plugged in the old BMW headunit in halfway through to make sure sound works which it did just not wen connecting the Joying unit.
Any tips or configuration I missed? |

If there is no voltage, I think some units are not setup to turn on an external amp by default. On the Joying unit, go into: - Settings - Factory, and the password is 3368 - Amp enable, and it should actually be set to "No Amp" - You may have to restart the Joying (swipe down from top of screen and tap the middle power icon) Also go into: - Device - Sounds - Amp should be On |

Hi,
The head unit link that you provided in the original post is no longer a valid link, would this be the same thing? https://www.joyingauto.com/newest-8-...-4gb-64gb.html Thanks in advance. |

The one you linked: https://www.joyingauto.com/newest-8-...-4gb-64gb.html has a PX5 CPU 4GB RAM 64GB ROM, Android 8.1 but it doesn't show the fast boot feature, which I found to be very handy. This one: https://www.joyingauto.com/joying-la...-with-dsp.html has an Intel Airmont CPU 4GB RAM 32 GB ROM, Android 8.1 and it does have fast boot, so I would rather get this one. |

It is actually the PAC RadioPRO RP4.2-BM21 which is specific for BMWs and takes care of interfacing to the wiring, steering wheel controls, warning chimes and PDC. |

Didn't have enough time to check if there was any voltage on the AMP wire but did try to connect it to the PAC 12v programmable wire without much success either. Not sure where to go from here, I've sent a mail to Joying and hope they might have some suggestions |
