[Q] Co-Pilot voice output acting funny on my Desire

I am pretty new to Android and still trying to get all the grips on I need. As of now, there is one thing that really bugs me badly.
I use the device for Sat-Nav driving a lot, I have a semipermanent installetion in my car from my previous smartphones. Basically just a power feed and a 3,5mm Jack that come out of the dash panel where the device holder is mounted. I recharge plug in for recharge as needed. The audio jack goes into the device, from there to a so-called Fastmute box behind the dash which is connected to the stereo head unit (the loudspeaker output cables running away from the head unit to be specific. The Speaker lines are interrupted by the box and just pass through whatever audio is being played back by the stereo. However, once there is current on the 3,5 audio jack (i.e. speech from the SatNav) the music immediately goes mute and you can hear the turn instructions in perfect quality through the car speakers. Once the signal fromthe satnav dies down stereo music comes back.
For my taste this beats most commercial, fixed systems.
Now, since I am on Android weird stuff happens.
On a first testrun shortly after I gut the Desire (which was o2 branded stock 2.1 at that point) I noticed that I do not get any announcements through the fastmute. Checked the jack, opened the dash to check internal wiring, retried a mp3 player. It's all good on that side. The accouncements come through the device speaker, hard to hear, easy to miss a turn etc. I do not why or how, but it seems that the audio routing takes a route different from other audio. This had me pretty much meh!
Well few days later, now with a ModaCo R8 custom ROM and Froyo I was hoping for good luck and gave it another whirl. Of course, no dice. When I plug in the jack of the supplied headset (which I assume doubles as a handsfree) I get the symbol for that in the upper symbol bar. When I exchange that headset jack with the regular 3,5mm jack the symbol looks different, but still vaguel like a set of speakers.
But now here comes the completion of the mindfaq... I had the SatNav volume at about medium (so barely hearble with driving ambient noise) when the phone went and I took the call through the Bluetooth Handsfree instaalled in my car and was distracted by the call (the car came euipped with the BT Handsfree from factory, so the stereo goes to "pause" and the conversation is routed into the vehicle speakers.. A few minutes into the call I suddenly hear a perfectly well understandable, clear turn instruction hopping into the phone conservation. I was extremely intrigued and was hoping that I discovered that CoPilot can route instructions either into A2DP or more likely emulate a "call event" that results in routing the audio into the according BT profile.
However, after that singularity I tried reproducing this for a god part of an hour, driving a route that forces many instructions from the SatNav, all the while calling my own answering machine fo have an connection established.
Sorry for the lengty explanation. Questions:
1 Has anyone ran into this before? What was your solution? Bear with it, switch SatNav software, avoid listening to music in oder to not miss any turn directions?
2. Is there a hack, hidden configuration that would enable me to _force_ this audio routint into the direction of the BT Handsfree, making it think it is an incoming call?

As a fellow co-pilot user I share your frustration.
You will probably find that it's nothing as technical as it not routing to bluetooth or whatever.
Co-pilot has a nasty habit of messing with it's own volume setting when a headset is plugged in. It tends to reduce itself down to zero without notification or cause. You would try to reset the volume, but firstly, it wont go more than a third of the way up, and secondly, it will simply jump back down to zero again on it's own.
They know about this issue and their response is not to use it with a headphone jack!
It is rather annoying!!

[Q] Help with new Headunit not powering off and some other minor problems

Hi all, new guy here with some problems.
I've bought a new headunit to replace my factory Skoda Stream Radio CD.
My car is an Skoda Octavia mk2 vRS year 2007, so any VW headunit should be OK in my car.
New headunit is a Joying Android 4.4.4 RK3188 with latest official firmware (June 2015).
I was trying to install it this morning for the first time and found several problems.
The most important one is the headunit doesn't power off even with my car completely shutdown and closed.
Headunit install instructions state there are two different methods to connect the headunit.
First and preferred one is using CANBUS decoder box, so headunit power is controlled through CANBUS decoder.
But if headunit doesn't power on when you turn on the car (that's happening to mine), you have to use second method: unplug CANBUS decoder box and connect ACC +12V red wires so that headunit gets powered.
With this second method the headunit starts up OK, but when i turn off the engine, take out the key or even close the car with remote control, headunit doesn't power off at all. I even tried to wait for 20 minutes but with no results. So i had to remove new headunit from the car to avoid battery drain...
I have upgraded firmware from Abril to June version so i got a new feature that allows to delay shutdown after ACC is off.
I set it to 30 seconds delay but still nothing. Headunit stays on.
I already asked to seller, and i'm waiting for an answer. But i thought maybe i could get some valuable ideas here at the forum.
Still don't understand why headunit is not powering on with CANBUS decoder connected. My car should support it, my factory Skoda Stream Radio CD is able to show climatronic info on display.
Other problems i found:
- Headunit buttons don't light even if i turn on car headlights. If i set button's colour in Settings\Elements buttons light for a pair of seconds to show new color, but then they go off again.
- I wanted to set Skoda logo at boot at Factory Settings but asks for a pin/password. Thought it was 126 but it isn't. What is the pin for Factory Settings?
- There's a slight buzzing coming from speakers when i turn on car headlights. That buzzing is not there with Skoda factory radio unit.
Long post, thanks in advance for your answers. :good:

Seems to me wrong or defected harness?
Does your car have factory amplifier? I had one that was making lot of issues. I figured out that the harness was the problem because they sent me a harness that is compatible with my factory head unit. But my car was standard trim that didnt include it. I had to cut one wire they told me to cut it. And it worked fine after that.

Thanks for your answer Scorbion,
Seller is going to send me a new Canbus box decoder. We think it must be faulty, that's why headunit doesn't power on or power off with it. Without Canbus box, ACC coming from VW harness is not a real ACC but a +12V to battery, because VW factory radio does all through canbus, and so headunit is always connected and doesn't power off.
Will update info when i get the new canbus box from seller.
Thanks

i have the same problem. can u fix it?

Did you solve this canbus problem?

Yes, new can bus decoder did the trick.
Long time ago though...

Hardware solution trumps everything
Had the same issue. Im also waiting for the supplier to respond. In the meantime, I just pulled the acc pin off the box and connected the radio to cig. lighter possitive. Works.

Default volume on startup, steering wheel controls

I have been running the Joying 3188 standard double din in my car for 3 months now. I have a couple questions, and wanted to see if anyone has run into the same issue
Any way of changing the default volume on startup? I have an Audison Bit Ten DSP in my car which I'm controlling my volume through, problem is every time I start my car the head unit starts at a volume of 12 and have to turn it up every time.
Also, I have the CarService app running automatically on startup, but if I turn off the car and the head unit goes into standby, then start the car back up within 30 minutes, CarService wont automatically start. Its only when the head unit fully shuts down that Car Service will start up again
Not a big deal, but I got N7player running on it. When I shut the car off, the head unit goes into standby and the music will continually play in the background for the 30 minutes, any way of having it automatically pause when I turn off the car?
I feel that all these problems could be solved using tasker, but I havent the slightest clue how to use it properly. Does anyone have solutions?
Thanks

FYI, i'll play with it some and see if I can on my Joying 7001
also have you gone into factory settings and played w/ the levels there? Unsure if it'll help.

Problem with reverse cam (canbus error?) - SOLVED

Hi
I have KLD unit that I've used for approx 12 months now without any issues (execpt from me playing with MCU and Firmware upgrades). I also have a reverse cam installed that has been working fine since day 1.
However a couple weeks ago the unit started to behave strangely, while I'm driving forward then the canbus suddenly send reverse cam signal to the unit and the unit goes into reverse mode. However I get the exclamation screen, since there is no live feed on the reverse cam (it's not powered on as it is connected to the reverse lights power source).
If I quickly change to neutral (still driving) and back to drive (automatic), the reverse cam screen disappears and unit works as normal. But after random 3-15 minutes it goes back into reverse cam mode, while still driving or even just standing still.
I've taken the unit out and connected it to a PSU and had it powered on for two days at my desk without any problem, so the unit it self seems in good condition. But when back into the car the problems starts again. Today I decided to disconnect it all wiring as well to check everything and look for any issues. I could not find anything "strange" with the wires.
So I started to play around with the reverse cam wires to see if anything was sending a signal while in neutral or drive. Turns out the orange reverse wire from the canbus is powering up randomly when not in reverse, disconnecting the orange wire from the canbus box takes the unit out of the reverse mode and unit works as normal (of course without reverse cam functionality). Same thing happens when I disconnect the canbus box itself completely, then of course my steering wheel buttons does not work (which they do when the canbus is connected).
I also connected the cam to the video IN and engange reverse gear then the live feed from the cam works fine when in ie. the AVIN app.
After doing all this fiddling and testing. I connected everything back correctly. However now the canbus seemed even more "broken", as it now engange reverse entirely when in P, N and D. And disables the reverse cam feed when actually in reverse
This leads me to the conclusion that the canbus some how has gone foobar. However I have no clue to what to look for. Is there a way to reset the canbus box itself, or do I just need to order a new one?
This is what I've done:
- Verify that all settings in Factory settings where correct
- Checked wiring and the car it self (car is BMW E53)
- Checked cam working and the wiring
- Loaded MCU and firwmare just in case
- Tested unit separate from the car (PSU power), working fine
The unit works fine otherwise.
As a workaround for now, I've disconnected the orange wire from the canbus box and connected the reverse cam video to video in. And just manually start AVIN when I need reverse cam
Hope anybody out here has any idea or clues for what I should look for?
Can these canbus suddenly "go nutes" or die?
Thanks

I would rather check the transmitter of the gearbox position. If it has problems it should be recorded as a fault
in your car internal memory. Maybe not in OBD, but deeper. Ask your garage to check the internal memory.

So could it be errors that torque is not able retrieve via ODB?
Thanks I'll check that out.

Most manufactures have at least two layers, maybe more.

I had something similar. Disconnected the pink cable from the reverse feed on the canbus box and hooked it up to the feed behind the glovebox for the reverse lights instead.

Disconnect the battery for a couple of minutes. That will reset the computer and clear canbus.
If it returns, then the PCM is probably at fault.

Hm, tried this. No go:-/
Better get my PCM checked out.
Could it be that my can bus decoder is broken? Anyone experienced this?

Just an update:
I managed to borrow a can bus decoder box from a friend, who has a similar unit as me.
That one worked fine and I had reverse camera as normal again with his can bus decoder.
So as work around untill I get a new can bus decoder box, I bypassed the can bus reverse cam trigger on the can bus decoder.
I made own reverse trigger wire connected from the reverse camera power and wired it to the unit reverse cam trigger wire directly.
Now its all working as before.

I have the same issue. There is another way to work the CANBus decoder (like any update etc), except to bypass the CANBus with cutting reverse cable. Please help me.

I have the same issue as well. I was in the process of installing the rear view camera, after which, my headunit is now stuck in 'reverse mode'. If i disconnect the ca bus decoder box, the headunit starts functioning without any issues. I can't find any info on how to reset or program the can bus decoder to its factory settings. No idea what to do at this point, other than order a new unit.

I think I have the same problem as you. Did you end up fixing it?
If my Canbus is plugged in, it's constantly in reverse mode. The only way to get back to the regular screen is to unplug the canbus or disable reverse mode in factory settings (in which case, reverse camera is disabled)
Do I need a new Canbus? Anyone know how this would happen and how to avoid it happening again?

Problema camara reversa (CanBus)
Hello,
There is, on the market, CAN-BUS INTERFACE UNIVERSAL ADAPTER INTERVAL CAN-01 / 02SPEED PULSE PARK BRAKES ETC
It is marketed by 'Motor Solutions and' Connects2 '
The CAN-Bus interfaces are designed to turn this digital data into analog, so the installation of an aftermarket car radio becomes simple. The interface creates the following for you, and saves you time and money in the process:
Speed ​​pulse signal
Ignition Wire
Lighting wire,
Reverse wire
Park Brakes
I think it applies to 'made in China' radios, but they should consult the sellers
Regards
Mário

PX5- steering wheel control issue & reverse camera blinking

Hello everyone,
I have a Dasaita PX5 and Android 8.0 for my Jeep Compass 2018. Problem is that (1) steering wheel controls have stopped working. Used to work for a while when the unit was first installed then one day just ceased to function. And (2) reverse camera video is blinking after driving for around 20-30 mins (doesn’t blink when engine is on and not running)
I've updated both the MCU (V3.45) and system update (20190731) to the latest ones in hopes of fixing it. I also went to factory settings and tried all canbus that had "Jeep" on it and selected the right model of the car but SWC still not working including the controls at the back of the steering wheel. The only thing that's working is the right side of the steering wheel which is the cruise control function.
I had an auto electrician check it and said “there's no problem with electrical side“ and now he's saying maybe the switches are broken (which I doubt) cos when the car battery was changed not long ago (SWC already not working this time), SWC came back to life but only for short period of time.
Please help me figure this out. Any advice would be greatly appreciated.
PS: also posted on android head unit thread. I wasn’t sure if I was posting in the right one. Thanks!

I'd try to disconnect the car battery for some minutes and see if the steering wheel controls return to work at least for some time.
If so, the head unit canbus adapter might be faulty,

I'd say there's a loose connection in the power feed of the CANbus decoder. More likely the ground wire is the problem. It could be loose or broken at either ends (including inside the decoder box) or along the length. Your electrician should know how to test for that.

Thanks for the reply guys. I’ll check this out and inform my electrician. Do you think the camera issue is related to this as well? I might need to order a new canbus adapter..

The HU gets the transmission is in reverse signal from the CANbus box so if the box kicks in and out so will the backup camera.

I put back the factory unit back in (factory unit worked without issues) but the steering wheel buttons still didn't work. Does this mean that the problem lies in the steering wheel buttons and not in the CANbus decoder?
