I have a turbo Corvette and am looking for a clean way to display boost pressure (PSI) and air/fuel ratios, and maybe more parameters ( like fuel pressure) without installing tacky looking gauges on my pillar or dashboard. I decided it would be a good idea to display them through a Android headunit as it'll offer a clean look, room to grow (won't need to buy more gauges for additional parameters).
The information will go from sensor > controller box > bluetooth OBD2 adapter > headunit (via bluetooth).
I will need almost instantaneous information so I can catch something quickly if it goes wrong.
Would this be a good idea or should I stick to gauges?
If you're curious, this is what I am planning to use to transmit the data: http://www.plxdevices.com/SM-AFR-Gen4-Wideband-AFR-with-MultiGauge-Link-p/897346002870.htm
I use a setup for this in my Mazda, Bluetooth OBD to my eonon headunit using torque, the response depends on the adaptor and the ECU, so in my case it's fast enough with sub second refreshes depending on sensor. RPM, A/F, fuel rail pressure, etc are instant. Coolant is per second refreshes.
I'd use it with my Supra but the aem infinity doesn't have an OBD port so I had to go a different route.
I'd pick a USB OBDII reader over BT. You could always try it first on a phone or tablet and see if it meets your needs - the bottle neck will likely be the ECU itself (or how frequently it outputs data to the OBDII port) or the OBDII adapter not the Android device.
Here's an initial review for the Ownice K1 (2gb ram/ 16gb Rom android 8 version) and from what I can tell, the first one to appear in English.
Background: This is Ownice's new budget model. No built in 4G support, no DVD slot, 4 core processor, slightly lower internal components (Amplifier, Tuner), TFT screen.
I ordered it on the 11.11 sale for about $200 with DHL shipping and added another 9$ for an external Mic. I ordered the version customized for Ford Mondeo/Galaxy/ S-Max.
Also ordered from other vendors: Ownice TPMS system (has not arrived) , Huawei E8372 4G wingle (arrived shortly after the K1 was installed), and reverse camera that replaces license plate light
Ownice shipped it three days later and it arrived in LA four days after that. From there it was brought to Israel by my kind brother.
Initial Impressions: came well packaged with protective film on the screen. Construction seems good. This is a slim unit and nearly all the connectors are breakouts from proprietary pin-outs on the back.
Installation:
Installation into a 2013-14 S-Max was quite easy as it simply uses the same mounting holes as the OEM unit, and the included connector is wired for the Ford quadlock harness. That said, it included no documentation whatsoever.
1) Connect three rear break-out connections to the back (Quadlock harness, A/V in/out cables, External mic input) and plug the included canbus decoder into the harness
1a) Notice that on harness wiring there is a wire that has a locking connector in the middle that comes disconnected. Assume this is for the reverse camera and connect it
2) Connect quadlock, revers camera RCA. External Mic, GPS antenna, and radio antenna
2a) Notice that they did not include a correct antenna adapter, run to local car audio guy and overpay for an adapter
3) (Spend next six hours wiring in a reverse camera through hatchback (not so easy!)
4) Shove all the wiring behind the unit (plenty of room there) and screw it in, replace trim, voila.
Future items:
5*) 4G wingle arrived a day later so I have only used it with the K1 in hotspot mode, which works fine. I have not gotten around to attaching it directly via USB
6*)TPMS system ordered from DX.com has not arrived yet.
In Use: In the realm of chinese android head units it is no faint praise to say that a unit simply works as one would expect it to, and this unit really does just work 99% as it should. I'll only point out some highlights and a few small disappointments:
+Unit powers on as soon as key is in ignition, stays on after car is shut down until door is opened (just like OEM)
+The reverse camera comes on BEFORE the unit is fully booted (right after the splash screen) so no significant delay there (this was a very pleasant surprise)
+No need to attach extra reverse wiring from reverse camera to car wiring, reverse is already wired via quad-lock
+Steering wheel controls work as they did with OEM unit (but mode button cycles through all inputs, even if they are not installed)
+My existing BAFX bluetooth OBD2 connected fine and works with the included version of torque
+Sound quality with OEM speakers is fine, at least on par with OEM head unit (despite what I've read about ST TDA7388)
+External mic is sensitive enough to work installed in hidden OEM mic location (grill behind map light)
+GPS reception/accuracy is better than my phone's
+Screen splitting works, and is useful
+Push the right knob in and the screen goes blank
-Radio tuner is not as good as the oem unit (I expected this)
-Bluetooth popup to answer calls does not appear for whatsapp calls
-Touchscreen could be a tad more sensitive
-built in media player does not seem to support WMA (thanks to yahoo music (RIP) I have a lot of WMAs) so I mostly use VLC
-No printed manual, onboard manual app does not work, and I can't find any manual online, so it took some futzing and going through the C500 manual to figure a few things out.
That's about it. I don't spend that much time driving these days so haven't gotten around to exploring all the settings and features, but so far I'm quite satisfied.
I appreciate the review; some follow-up questions...
Please tell me if steering wheel controls (up/down track) work on all music apps or just the stock one. Also let me know if you hear any background clicks/pops/noise when WiFi is being accessed. How is the Bluetooth calling quality - can callers hear you ok? Finally can the stock radio and Bluetooth apps be used split screen?
Thanks!
Jeff

1) Steering wheel controls work with all aps.
2) Haven't heard any noises caused by wifi
3) Bluetooth call quality is good, definitely go with the external mic
4) Yes, those apps and most others work in split screen.

Thanks for the answers. One more question, sorry. Does Ok Google work, and/or can you use Google to initiate a call just using voice or microphone button plus voice? Many units "understand" the request to call but fail to be able to put through the call.
Thanks again!

Sorry for the delay in replying.
As far as OK google calls, since the head unit's Bluetooth functionality works as a microphone/speaker, when you run a google now command on the HU, it thinks you want to make a call using the HU, but it has no phone function of it's own, so it cannot place the call. What would be needed is a button on the HU that activates the phone's google now listening. I don't keep my phone in constant listening mode, so not sure how it would work in that situation. Hope that helps.
Here's a few more observations, not entirely good:
1) The steering wheel next and previous track buttons are reversed.
2) There is a problem resuming Bluetooth streaming from my phone. If you push the play button on the HU Bluetooth app after a restart it will freeze and force a reboot.
3) GPS reception is generally excellent with very quick fix, but occasionally for no apparent reason upon startup it will take 5 or so minutes.
4) Even disabling all of automatic time setting, the unit will inexplicably get an hour ahead when booted and then correct a few minutes later.
5) I can't figure out if there is a way to get the Huawei 4G USB router I bought to function as a modem or only as a hotspot.
Hi Doncres,
I've just finished installing my own Ownice K1/G10 unit for my Hyundai Santa Fe.
Installation was a little bit trickier since in order to use the car's original gps antenna, microphone and rear camera I had to cut some wires and change connectors, as well as installing a stepdown DC-DC converter to get the weird 6.5v power required by the original rear camera.
I've been playing a little bit myself with the unit and, given that I'm quite satisfied with it, I would like to know whether you experienced any of the following little annoying problems:
- handsfree call via bluetooth: remote party is always complaining about a small amount of echo
- general audio volume low even at maximum volume (+30), especially for bluetooth phone calls
- the bluetooth active call popup rectangle gets always in the way, even when the rear camera is triggered by the reverse gear, giving some troubles when parking the car and talking to the phone
- Netflix app not working: I had to install an old 2015 version targeting Android 4.4
- parking assistant lines on the rear camera view have wrong perspective angle in comparison to my camera's viewing angle, thus resulting in a projected trapezium rather than a projected rectangle (i.e. the lines are not parallel to actual parking lines); I know I can disable them, however I'd like to change their perspective angle to match the camera
I read somewhere that there are two hidden service menus on Ownice units: the first is accessible via car settings (the "1260" menu) and this works on my unit
The other should be accessible by dialling a specific string in the phone app, however it seems I cannot start the phone app since the K1/G10 comes with no 3G/4G hardware. Any idea on how to enter such menu?
Thanks,
Alberto

Hi, I'm not sure I can really help other than to confirm a few of the the issues.
-Don't think I have an echo issue, but there seems to be a delay until a caller first hears me.
- I get very good volume. I would assume this is an issue of whether the built in amp is a good match for the speakers. Could be an issue with the impedance.
-Yeah, the call button overlay is sometimes annoying, it can block nav screen as well and no way to hide
-I noticed that Netflix was no showing in the app store, but not a big use for me
-the camera I bought has built in guidelines so I disabled them.
-no idea bout the service menu
The only issues that really bother me are:
-the occasional GPS not acquiring satellites, which I now think may be from a defective antenna. I ordered a replacement and we'll see if that helps.
-the fact that if I have an app like stitcher playing, i then get in the car and it stops it when it connects to the BT, but when I go to the BT music app it will either resume fine or if I pres play it will crash the entire device and force a reboot. Mostly I just run streaming apps on the Unit so not much BT streaming anyway.
Also, my TPMS unit finally showed up 2 months after ordering it from DX.com. Looking forward to installing that some time in the next couple of weeks.
Hi.
I am newbie, and i may be wrong in posting the question.
I got 2 din touch Android for Nissan Murano 2018 - model K1, 2 / 16 GB. Ownice 8227L.
On the manufacturer's website, the model has not been supported by software updates for a long time.
Last owner tried to update it with different firmware versions, including those downloaded from this site, and from 4pda. initially did not save the software that was on it from the factory. Now - it has a version of Android installed in which the radio does not work. Everything works, sound files from usb card play, except the radio.
Help me please, where can I get the firmware on it to make the radio work?
Hey There!
I have a PX5 Android Radio (xtrons) built in my Mercedes-Benz E-Class (W211). This car has a display built in the speedometer, where you normally can search for another frequency or play the next DVD track.
I can play the next song with steering wheel buttons with the PX5, it even shows a small "AUX" text when AVIN is open, or "BT" when i play music via bluetooth. With the media player open, I can see the time of the track and can move forward and backwards.
Would that be possible with Spotify installed on the px5 to? Maybe with an android application, that sends the text via the canbus to the display? If that would work, it would be even possible to show Navigation on it.
Hopefully somebody could help me find a documentation or sth, so I could try to code such an application.
I have the same car with a PX6 head unit. It seems it's not possible to display any track info from Spotify or navigation info in the speedometer display.
Do you have the Harman/Kardon Logic 7 sound system? If so, are you using a fiber optics adapter with your head unit?

I don't have the Harman/Kardon Logic sound system. It should be possible to write Text or pixels to the Dash Display via the canbus. It already displays "BT or AUX" so there also should be existing code that does this.
It would be mind blowing to have the Navigation Info in the Dash Display among with Radar Detection etc...
Hi, I have a CC2 Plus radio to Renault Megane 3 .After installing the radio, the outside temperature, i.e. from the canbus, is not displayed.
I wrote to tech support teyes said they disabled this feature and that it will no longer be enabled. Only the one downloaded from the Internet is displayed, not the canbus temperature sensor. Does anyone know in any way it could be displayed on the radio screen
Not MTCD, requested move to [Android Head units].
Op, suggest a read of the forums and a little familiarising before posting.

was it actually working before
i noticed the same just installed the unit few days ago
did you managed to do something about the joystick near the handbrake or edit the controls on steering wheel ?
Yes, it showed temperature from sensor ( magistral can bus ) but Teyes switch off this. I haven't got joystick but I saw videos on YouTubute and it working with this radio. when it comes to the output on the steering wheel, turn it down, turn it up and set the applications on the button. an image is also displayed when the door is open.
does your original radio was the single color screen one or tomtom navigation type?
Want one with built in GPS chip, can take the abuse of a off road 4x4 , Has at least a volume knob.
It has to be mounted securely it can't float like the ones I see. I'll be adding apps for navigation, engine monitoring , camera inputs at least 2ea etc.
Outputs for a Amp, wifi for phone and usb for a I pod. Cell chip?, Plus non can bus.
Ideas?
Thanks
