Steering wheel programming

I was able to program the buttons on my steering wheel and they all work. My problem is there was no option on the Android 4.1 Head Unit Steering Wheel screen for CH up or CH down, resulting in the next station being selected instead of the next stored channel. The only option I found to program my channel buttons was to use NEXT and PREVIOUS. Anyone encounter this or have a solution? The Unit is not rooted yet.

I finally read through all 76 pages of this Thread! YAY! Very informative, and keep up the good work. Thank y'all!

I saw your Post #2204 of the OUKU - Unbranded 6.2" 2 DIN Android Car Stereo Radio Head Unit thread. After I found out that you had a 2006 Honda Civic EX, I looked up Axxess or PAC Audio installation guides and found out that your system uses an open resistance loop. So, you wasted your money getting a third-party SWC adapter but I didn't want to add insult to injury especially with what you had to go through to program the Axxess. I can sympathize with your frustrations with it because I also hate Axxess's automatic program routines.

All that was necessary was to connect the radio's Key-1 to Pin 7 (Pink) of your Civic's connector then you would connected ground to Pin 6 (Brown) of the 20-pin connector or Pin 22 (Brown) of the 22-pin connector.

[MENTION=5389783]donaldta[/MENTION] : May i ask a question, regarding the conversations of can and your knowlegde about it?

I have an Ford Mondeo built in 12.2000. So i read, what you are writing and searched around, how the connectors in my car are built. I found a plan and was at my car to measure the two cables, which are assigned to my stearing wheel control.

If the harness is not connected to the radio, i am not able to measure anything on one of the two cables. If it is connected, the "standby" voltage is 4.75, dropping down to different voltages, when pressing a button.

This was measured on pin 10 (10 and 11 are for SWC), on pin 11 i can never measure anything. Whether a voltage than a resistance.

Is it possible, the radio gives the voltage? I tried different positions for the grounding by the measure, car and original radio. It was always the same result. Pin 10 only gives voltage datas, when the harness is connected to the radio.

I will buy some stuff to connect the cables for a try on monday. I just would like to know, if i have to buy another tool, or if it works out of the box.

Thanks for any hint!

I tried the exact connections you stated above and the SW buttons would not function properly for me neither on my old head unit (3 years ago) nor this new one. I don't know why, it doesn't make sense, but unfortunately that's the the way it ended up. Anyone having to use the ASWC-1 will need to manually program it to #11 "Metra OE" for it to work with these Head Units. Hope this helps somebody.
[Android Head-Units] donaldta:
I don't think your car uses CAN, unless you meant to ask questions about SWC. It sounds like your car is using voltage references not CAN bus to transmit the SWC signals. If you press a button and get a steady voltage reading on your multimeter then its an analog signal not digital. A digital signal isn't really all that easy to pick up with a multimeter because it takes time to measure the electrical properties, whereas a digital signal is a series of timed on/off signals which happens in milliseconds.

If all of your buttons register a unique voltage value on pin #10 then I wouldn't worry about pin #11. If anything, I would probably guess that pin #11 is ground. If you measure resistance with Pin #11 to the positive lead of the multimeter and the ground lead to chassis ground, does it measure 0 or 1? "1" means there's no connection or 100% impedance where was "0" means zero impedance and solid continuity.

As far as it working out of the box? I can't really answer that. It seems that you might be in the same boat as [MENTION=1537970]sorin129[/MENTION] with a SWC that utilizes voltage references. So, if either of you can get it to work then both of you should be able to get it to work. As far as I can tell, the AN 21-U's SWC's default mode is to measure resistance to ground. The trick for it to work for you to is if it is possible to measure the voltage values.
[Android Head-Units] ThePapabear:
Sorry, of course i meant the SWC. I´m very shure, my car is not using CAN, but i am not shure if it uses "simple" analog signals.

I will measure again tomorro on my second cable, because i can not remember if it was a 1 or a 0 on the display.

I just will give it a try on monday and then tell if it works or not. Thanks for your suggestions!

[Android Head-Units] donaldta:
Interesting. It would interesting to find out with a multimeter if those the connection is indeed correct. I'd test voltage then resistance of the aforementioned pins in your case. If it truely an open looped system you would get unique resistance values for each SWC button you press while positive lead of the multimeter is connected to the pink wire and the negative lead to brown wire. Although, I suppose the resistance values can be too close to each other for the AN 21-U's SWC to register a difference. I suspect, that the Axxess SWC-1 is making up for some electron condition since it is providing its own analog values with the "Metra O/E" settings.

By the way, I believe it will also work if the Axxess ASWC if it is set to Pioneer or Sony mode, since they both use analog signaling as well. Unlike JVC, Alpine, Clarion and Kenwood which use digital signals.

Did I misinterpret what you meant by the following...

Does the voltage continue to fluctuate when you hold down a single button

or

is there a unique voltage reading per button? If it is the latter then that is a "simple" analog signal.

:good: Good luck!
[Android Head-Units] sorin129:
Ok so I just tried every possible wire combination and still have the same problem with SWC. I did measure the voltages with the engine off with the key in the accessory position and also with the engine on. Here are the voltages:

With the engine off and key in accessory position:

No button pressed = -0.12

Volume + = 3.20

Volume - = 2.72

Next = 1.89

Previous = 2.30

With the engine on:

No button pressed = -0.10

Volume + = 3.60

Volume - = 3.06

Next = 2.15

Previous = 2.60

At this point I think either this unit can't read my car signals right or it"s swc adapter is defective. I can sort of "program" the buttons but not the right way and it's does not work the way it suppose to. Here is a video:

If anybody has any ideas, please let me know otherwise I will probably by a third party swc adapter

Can you tell me for the Metra Axxess ASWC Universal OEM Steering Wheel Control Interface that you installed what wires did you use to connect the Female 3.5mm connector? Did you use Key 1 and Key 2? and how? I'm thinking about getting that adapter and I understand that you have to program it manualy to #11 Metra OE but I also know that adapter has a male 3.5 mm connector and our units have no 3.5 female connector to plug it in. So I assumed that you used the 3.5 mm female connecter that comes with the adapter right? If yes can you tell me how you did it? thanks
[Android Head-Units] donaldta:
The Axxess ASWC comes with a 3.5mm female cable that outputs two wires brown and brown/white. You would plug in the standard 3.5mm male cable into this and if memory serves me correctly, the brown/white wire is ground so the brown wire would be connected either to Key-1 or Key-2.
[Android Head-Units] sorin129:
Ok thanks. I guess I'm going to have to buy this adapter since I can't figure out how to make work without it. So fustrating because I was so close of getting it to work without any adapter.
[Android Head-Units] omarko:
can someone recommend a good equalizer ? happy to pay for one.
[Android Head-Units] donaldta:
Okay. I understand. But, just to double check... you tried it with Key1 connected to B31 while Key2 was continuously grounded, right? Because that would have been my first attempt.

Here is the seller's instructions without the pictures

Click menu icon

Click "Setting"

Chen "General"

Then "Steering wheel"

Click "START"

Then click each button to learn

Connect "KEY-1 or KEY-2" to GND line.

The button will turn to grey when you finish learning

Click another button

The button will turn to grey after learning

Click "END" to finish the learning.

Try it with my "Engrish Translation" just to see if it works.

Connectet Key-1 to B31

Click menu icon

Click "Setting"

Chen "General"

Then "Steering wheel"

Click "START"

Then click a function to learn

Hold down the respective SWC button and momentarily touch the "KEY-2" wire to Ground.

The button will turn to grey when you finish learning

Repeat the process for each button/function combination

Click "END" to finish the learning.

I don't know how much time your willing to wait but maybe if your willing let me contact Peter Chan directly, I can ask him specific questions about the SWC to make sure there isn't some magic that your seller isn't relaying to her engineers appropriately.
[Android Head-Units] cyberpapa3:
Yes I used the 3.5mm female connector. I connected the brown wire to "Key 1", and the other wire is not used. I did not use :Key 2". The ASWC-1 has other wires for other vehicle applications. The Grey/red stripe - goes to Pink wire (Pin 4) on the Civic's 20 Pin connector Civic.
[Android Head-Units] sorin129:
Yes I did try that combination also. I tried every combination possible lol. I just ordered that ASWC-1 adapter so I'm giving up on trying to get it to work this way lol

Anyway I learned a lot and thanks for your help. I hope this $50 Axxess adapter will work easier that this lol I should be able to connect that pretty easy because now I now where all the wires are lol

---------- Post added at 09:27 PM ---------- Previous post was at 09:21 PM ----------

Thanks a lot. That was the only thing that I was not sure about, the female 3.5 connector. The rest of the wires I do know where they go for my car. I use the pink wire to connect to A1 wire on my 24 pin harness. and the only other wires I use is the red ACC wire and black ground wire. The only thing that I was not sure about was that 3.5 mm male connector ( because we don't have a female connector on our radio) So just connecting the Key 1 to the brown wire should work. Thanks
[Android Head-Units] donaldta:
Okay, no worries. You also have to two points of connection with the Axxess to your SWC. Behind the radio (Radio C1 connector, pin A1) with the ASWC (Pink) or at the Steering Wheel Column on B31 pin. Although, I am not sure which color wire you would use for that one. The problem with the Axxess adapters is that if it doesn't auto-detect through the correct wires connecting to the car or the head unit then it really is a big PIA to manually change it. And, it is one of the worse written manuals I've seen. Your sort of expected to remember LED flashes then time when you press and hold certain buttons as it knows them not as you've programmed it.
[Android Head-Units] sorin129:
Yeah I'm going to connected to C1 connector, pin A1 because I would not know what wire to use for B31 pin. As far as auto detection, I know I have to program it manually Metra OE because it won't auto detect our radio. We will see when I get it how easy it is to connect it.
[Android Head-Units] cyberpapa3:
The Red wire goes to ACC. The Black wire to Ground. The Grey/red stripe - goes to Pink wire (Pin 4) on my Civic's 20 Pin connector. The Brown wire (Pin 5) goes to ground. This is correct for my Civic. I also have a drawing that shows the Pink wire as Pin 7 and the Brown wire as Pin 6.

I tried to add a drawing of the connector, but I couldn't paste it for some reason. Sorry about that. Hope this helps.
[Android Head-Units] donaldta:
When it does't auto-detect the head unit, it will default to Alpine which I think is pretty funny. It seems so arbitrary for that to be the fall back option as opposed to any other.
[Android Head-Units] sorin129:
Don't confuse me lol. I have a different car than you so for my car I need to connect the pink wire to A1 pin, Red wire to ACC and Black wire to ground.

The 3.5 female connector I was interested to know how to connect it because that it should be the same no matter what car you have. That has to do with the radio that you have and since we have the same radio. I was interested how you got it to work for you and you did answer my question: the brown wire from the female connector goes to Key 1 from the radio and the other wire is not used from the female connector. Key 2 is use is not used ether. Also I have to set it manually as Metra OE radio. I think I got it right from what you said. thanks
[Android Head-Units] donaldta:
Heh, heh. Did you just respond to yourself on a public forum? :laugh:

Incidently, you cannot paste an image into a text field. You'd either have to embed the image from a webhost using tags or upload it as a file attachment.

Btw, could it be that the actual difference is relative to which way you're looking at the connector? It is ten pins so depending on how you number the wires the left to right and the way you're looking front to back and which way is top to bottom can make the number change based on your perspective.

For example, the "top" row of the 20 pin connector with the Pink wire #4 and Brown #5

[1][2][3][[B][COLOR="Magenta"]4[/COLOR][/B]][[COLOR="Sienna"][B]5[/B][/COLOR]][6][7][8][9][0] Front (Pin)

[0][9][8][7][6][[COLOR="Sienna"][B]5[/B][/COLOR]][[COLOR="Magenta"][B]4[/B][/COLOR]][3][2][1] Back (Wire)

Hi all. I have an xtron td788a unit, which shares a very very similar hardware to this unit, main difference my unit is a single din one. Now I have been able to root it with Baidu Root without any problems, all works well, but for love of god I cannot make a 3g modem work with it. I'm trying to bring to life a E353 huawei with this unit. I plug in the stick boot up the head unit, but I do not see any signal or anything. However if I go to the mobile settings I can search for network, I see my network and I can even register to it. The minute I connect to a Wifi network, the phone bars also comes up and in the notification bar I can see that it's connected to my operator. I tried PPP widget, but it fails as well, it connects and in 1 second it's disconnected again. I have no option to add APN settings because there is no button for it, so I have tweaked the apns-conf.xml and the com.android.settings_preferences.xml so now the correct APN does show up in the APN menu and it is selected as well, but still no joy of connecting to the net, I mean I still do not see the phone bars or anything. I tried: svc data enable / svc data disable to no joy, I also tried the method described here: http://xdaforums.com/showthread.php?t=2172914 which does bring up an IP to the device but still no connectivity. It's really doing my heading it cannot be that complicated to bring up a data connection, can it?

To recap:

- If WIFI is on and connected, 3G network comes up

- When wifi is of or disconnected, 3G network goes down.

Logic?

Any help is appreciated.

2. Fixed radio widget for 1024

3. Fixed the color separator strips, radio buttons under the screen 1024

4. Corrected some bugs in the launcher

5. In the launcher, you can change the bottom bar transparent, long tapom button all programs

Is there some important things that I must know before order? All these Head Units on ebay looks pretty similar (only another look or 7-8" screen differences, but also RK3188 and android 4.4.4. support).

Thanks for anwser :)
[Android Head-Units] Emil Borconi:
Sorry if the question is stupid. Does any of the AN-21 units have a so called "dormancy" setting? In the factory setting I can select the power off state of the device, which is either full power off when I switch of the ignition, or dormancy (which I guess is a kind of quick-boot thing). When I select dormancy the device boots up in a few seconds and usually but not always opens the last app which was opened. However it has a nasty effect on killing all the services, so I cannot setup a tasker profile, because the tasker service gets killed while in dormancy. Of course I can select the full shutdown and then have a full boot each time, but that is rather slow compared to the other option. Like I mentioned my unit is slightly different (single din fold in display) although sharing the same hardware. Did anybody else faced similar problems?
