Sorry for the delay. Been dealing with emissions testing issues and home issues. My settings. My button mapping is the same as yours.
Weird. The place I'm hosting has these upright. If you right click and open these in a new tab they are upright. But you can see how I have it set. |

Thanks for posting those! I finally figured out what was wrong with my steering wheel controls and having the correct CANBUS setting from that menu helped.
On the back of the head unit, apart from the wiring harness than connects to the CANBUS adapter, there are 4 sets of wires coming out from where the Bluetooth and WiFi antennas are: they are labeled CAN OUT, CAN IN, IR, and KEY. When opening the unit from the factory they had the CAN OUT and KEY wires connected. I played with the different combinations and when I connected CAN OUT and CAN IN the steering wheel controls worked! Also, about the celsius/farenheit and km/miles conversion when the CANBUS first connects: there's an app on the head unit called Car Info I believe. If you open it up you can get to this screen where you can set those and it will change the dash and HVAC setting as well. You can also activate seat heaters from that app (although it doesn't change the "C" on the notification bar of the head unit which is kind of funny. I doubt it's 64C in my garage). Thanks for your help! I hope you get yours working the way you want. |

Haven't been back in a while. Thanks for the info. The units have been annoying me but I haven't delved into the settings much. I've been pretty happy. It's nice to have a backup camera and retain SWC. For some reason my HU seems to reboot sometimes, and sometimes not. It doesn't lose settings just doesn't fast reboot.
I'd do it again if I had the chance. I might see if this will work in my daughters 2008 Mini. Can't find much info on that Canbus but she could really use a backup camera and Waze. |

I used this rectifier for the camera:
https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 This mount: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 The CANBUS adapter from joying for the 3 series, and I got this generic backup camera that attaches to the license plate since the convertible (mine) has a different trunk handle than the coupe so the trunk handle backup cam that Stubbie Blue used doesn't fit. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 |

Went ahead and finally installed my Joying 8.8" unit over the weekend along with the e90 CAN adapter and the trunk handle backup camera. As expected, already running into a few small issues.
Overall still getting used to it, and dialing in the settings. Any pointers / recommendations are always welcomed. Adapter cable to route USB from the original location is on the way, and I've already wired up the OE AUX port. I'll try to get some pics up to help those trying to keep these functional. |

Alright, so a bit of an update:
Still waiting on the adapter cable to connect the OE USB to the headunit to come in from China. Haven't gotten around to shifting the screen over yet either. If I can't get the CAN issue sorted sooner than later, I'm tempted to unload this for a name brand non-android unit along with conventional steering wheel adapters. The settings not saving along with the cheap gong sounds are beginning to wear on me. |

thats really odd on the canbus controls. Also, do you have the constant power tapped into constant fuse?
You don't hear of people having issues with the steering controls on the dedicated units and the harness they provide is supposed to remedy that for the universal units. |

In regards to the steering wheel controls, I wasn't sure if the CAN settings inside the radio for BMW forces certain options, but the flexibility to map them to my liking would be nice. |

Thanks to these posts that sparked my idea about using a joying unit. I did a quick DIY as my way of giving back. I have a more in depth review I will post soon too. Thanks to everyone who has shared their info!

I've been messing with my Joying head unit a bit the last week or so and ironed out some issues I had with it.
First, what isn't working - every time I turn on the car it still changes miles to kms and Fahrenheit to Celsius. I don't think this is lack of power to the head unit but I suspect has something to do with the CANBUS adapter? When my CANBUS adapter wasn't working or wired correctly (with steering wheel controls and whatnot) it didn't change the units on startup. As soon as it was connected correctly the problem started occurring. I finally have my backup camera installed - that went pretty smoothly and works really well. I had to wire it to constant 12v from the battery (whatever came from the head unit wasn't sufficient) but the backup camera I ordered from Amazon actually had the relay with it so I didn't have to buy one separately. The CANBUS even curves the reverse lines with steering inputs as if it was OEM. Using the ZLink app on the head unit to launch Android Auto doesn't give you full screen on my unit because the screen is too wide (running Android Auto natively does the same thing). In addition, you can only launch it on ZLink through USB. After a lot of Googling I found that Android Auto is scalable to any size screen but it's up to developers/manufacturers to implement it correctly, which Joying hasn't done here. It leaves a "window" off to the side that just shows the Android Auto logo which is a waste of space and just doesn't look great. However... There is an app on the Google Play store called "Head Unit Reloaded" (HUR) that was developed on XDA Developers and is a container to launch Android Auto like you would on any other head unit - that is, it runs everything through the phone including the GPS, audio, phone calls, messages, internet connection, etc. This developer has also created a companion app for Android phones so you can wirelessly run Android Auto. It's a little involved to set up and get working but now that it works I'm loving it. As you can see from my picture it scales to use the entire screen now! As soon as you launch the HUR app it senses the phone and then launches Android Auto. |

I haven't been back to this thread a while. My only real issues are still the units always switching back to metric issue. All my SWC worked from the getgo. The unit seems to sometimes keep it's memory, and sometimes not but it's no big deal. By that I mean it quick boots to where I left off sometimes, and others it seems to go through a full boot. No real problems I just wait another 20 seconds before I start driving.
On rare occasion my camera will have a blank screen but it might happen 1 out of 10 times driving it. Lastely, the iPhone mirroring through USB or BT works well and I usually connect via USB so my iPhone will charge. Overall, I can't complain. Thanks again to Stubbie Blue and others input. |

Hi, I'm in the process of ordering the Joying 9" unit with the E90 canbus harness and was wondering is it straight forward hooking the harnesses up together, ie which wires go with which and what about the canbus in/out plugs on the back of the unit.
Thanks for all the information you've posted on here, I'm sure I'm gonna need it. |
