[MTCB Android Head Units Q&A] cool_t5:
Hi i have AN 1001 GMC

can i update the MTCB-RM1-V1.85 dirict to v2.22 or i have to update to 2.04 then 2.22

also can you give me their new ROMs pls.

and did you update your unit to 4.4 ? if yes what did you use coz i couldn't find my unit in the web

thanks
[MTCB Android Head Units Q&A] Core-Lokt:
Would like to know the year and car, also. I've had no luck getting SWC going in my truck (2005 Dodge Ram)-even with an Axxess ASWC-1. I might get a PAC interface if I think it'll work.

[MENTION=2944194]TT_Vert[/MENTION]-did you ever get SWC going on your Kia?
[MTCB Android Head Units Q&A] dureal99d:
sTeering wheel controls

Ok from the look of it you need the (>>>>>>>SWI-X<<<<<<<<) interface

and I don't know if your audio is amplified or not but you need this if it's not amplified other that its not compatiable (see) >>>>>AOEM-CHR2<<<<<<<<

I will post pictures soon of how I did mine to give you some ideas. what kind of head unit do you have and can you post pictures of the wires?

I will tell you this if you have the axxess ASWC -1 , and your radio is an Chinese after market more than likely your radio has a set of wires named>>> key 1, key2 and key ground. you should plug in the provided 3.5mm female adapter to the male 3.5mm adapter, (note) the female adapter usailly has solid brown =key1 and brown white =key2, you should be able to hook up key 1 to the to the provided brown wire from the adater and it should work that's assuming that you have hooked up the power that powers the ASWC - 1 AND IT TURNS ON. remember you only need the key 1 wire to the brown wire, you do not need use key2 (note) I have heard of cases were key 1 to solid brown, key 2 to brown white and key gnd to chassis ground but id start with only the key 1 to solid brown of the 3.5 female adapter. tell me how it works

oh and my vehicle is a 2005 gmc Yukon denali
[MTCB Android Head Units Q&A] TT_Vert:
This was an S160 unit but yeah SWC were the easy part. Canbus never worked right, always showed same 31.5 C and never changed on either driver or passenger side. If your SWC are a resistor matrix then it should be very easy w/o any type of module.

[MTCB Android Head Units Q&A] Core-Lokt:
Here's some pics from the install of the ASWC-1. It's not in there, anymore. I never could make it work. I followed the instructions perfectly with no results. I called Metra and they said to re-map the ASWC to Pioneer-Jensen or OEM Metra. I know I set it up right because the lights flashed to show it learned. I returned it to Crutchfield and they even acknowledged I did everything right, including soldering. Pin 14 on my factory harness is the trigger. My truck had the basic four speaker configuration.

[IMG="Chrysler-ISO Harness With ASWC-1"]http://i1119.photobucket.com/albums/k623/Opus_Dei/truck/IMG_0706_zpsvyxahegy.jpg[/IMG]

The HU is a Joying UQ-128 and the SWC are resistive and my truck is the last year before CANBUS. There is no key ground wire (only Key1 & Key2) on this model, although I think Pumpkin HUs have three. Theoretically, it shouldn't have needed anything to work. Joying kept saying I needed to ground. I still can't figure out what they meant. The HU chassis is grounded through the harness, and there's only one SWC wire to work with.

[IMG="ASWC-1"]http://i1119.photobucket.com/albums/k623/Opus_Dei/truck/IMG_0705_zpsbzpso8py.jpg[/IMG]

I accidentally got one button to save, even as it didn't work in the SWC. That was grounding HU Key2 wire and Key1 was connected to the brown/white wire off the 3.5MM jack lead.

[IMG="Saved, But Non-Functional At Steering Wheel"]http://i1119.photobucket.com/albums/k623/Opus_Dei/truck/IMG_0707_zps0padqltn.jpg[/IMG]

I tried every wire combination I could think of. I tried altering Factory Settings. I'm stumped. Any advice is appreciated.

---------- Post added at 12:20 PM ---------- Previous post was at 12:09 PM ----------

Forgot to add before I even got the ASWC-1 I tried to make the SWC work. Thinking back, the Chrysler-ISO harness didn't have the brown wire so I bought a Scosche pigtail, cut it apart and inserted one of the jumpers to bridge the sides. Still, it didn't work.

Now what I can't quite remember is did I keep Wheel Study selected. There were a few settings I didn't quite understand the function of, like Wheel 3.
[MTCB Android Head Units Q&A] Core-Lokt:
I pulled the HU and took a better picture.

[IMG="Harness"]http://i1119.photobucket.com/albums/k623/Opus_Dei/truck/IMG_0089_zpsuezxqmhr.jpg[/IMG]

That short pink wire siamesed to the brown wire is where I removed the ASWC-1. I again tried to wire Key1 to the brown wire with no luck. I tried grounding Key2 to no avail.
[MTCB Android Head Units Q&A] TT_Vert:
I think you can just ground that SWC ground button but I'm fairly sure it needs to be grounded. I actually read about someone having a similar issue to you w/ SWC, I'll see if I can find it a bit later.

Dave
[MTCB Android Head Units Q&A] Core-Lokt:
OK; I could pull the steering column shroud. Hopefully, if you find that post it'll detail if that ground off the SWC buttons goes to chassis ground or to one of the key wires. Thanks much, TT!
[MTCB Android Head Units Q&A] TT_Vert:
Sorry I meant ground that swc wire from the HU, not ground the actual switch. It is just needing a ground for a resistance value.

Dave
[MTCB Android Head Units Q&A] Core-Lokt:
So, SWC trigger wire to Key1 and Key2 to a chassis ground? I had thought about that and tried it before the ASWC-1, with no luck. I even tried it earlier today.
[MTCB Android Head Units Q&A] TT_Vert:
No i think the HU wants the same ground reference that the SW controls see for resistance calculations but if you don't have it you have to supply chassis ground I'm guessing. Do you have a schematic for car to know you don't have a ground for SWC?

Dave

AFAIK, it's pin 14. My truck didn't originally come with SWC, but I added them some time back-and they worked fine with a stock Chrysler unit.

As memory serves me, I had to cut out holes in the back of the steering wheel, install the buttons and plug that harness into a socket around the air bag/horn sockets. Then, I had to run a single jumper from an existing plug on the bottom of the steering wheel to the MUX on the back of the gauge cluster. There was also a separate chassis ground I had to make and used an existing ground screw on the metal dash frame that other circuits grounded to.

EDIT: I'll rig up a temporary ground from Key2 to that exact same ground used with the SWC I installed and let you know how that worked.

[IMG="Key2 Grounded to Same SWC Chassis Ground"]http://i1119.photobucket.com/albums/k623/Opus_Dei/truck/IMG_0095_zpsdotvumun.jpg[/IMG]

This is no different than what I was able to get quite a while back-only VOL UP is saved, but it doesn't function. No other functions can be saved.

[MTCB Android Head Units Q&A] dureal99d:
at worst come to worst

The reason i say this is because i read up on you stereo And then you vehicle is using a steering wheel that was not designed for it (custom). Well at worst come to worst you can always use this. look up >>>>Car Universal Steering Wheel Control Key Button Speicial For Car Android DVD/GPS Navigation Player Bluetooth Phone #CA4252FK<<<<<

I had to erase you stuff cause unfortunately and with great disgust i cant post links. I have to tell ya i dont see how it helps security but i can see how it henders help. anyways. see this and it should do for you.

[YOUTUBE]https://www.youtube.com/watch?v=45t9-meX5qY[/YOUTUBE]. Hope it helps
[MTCB Android Head Units Q&A] Core-Lokt:
Thank you. I know about pics/links, since it wasn't that long ago I got that privilege. I'm going to try the PAC module. For whatever reason, sometimes one brand works where another (Axxess) doesn't. The Pioneer-specific module mentioned in the video kinda corresponds with Metra saying to re-map the ASWC-1 to Pioneer/Jensen. Honestly, I never used a multimeter to determine values. I thought things would either work or not.

The SWC are Chrysler, though, and not some aftermarket stuff. My truck is an ST, but these are the same controls/wiring as in an SLT or Laramie model. I knew about the clamp-on controls and I even knew about how people hacked their harness to get the two leads direct from the buttons. I'll do without SWC rather than the last two choices.

It might be a while, but I'll report back. Thank you, again.

EDIT: I watched the video again, but this time read the comments. That car doesn't have resistive SWC, so the ohmmeter was reading what the PAC SWI-X converted..

Hey guys,

I just bought an elm327 bluetooth device, after scanning new devices the new device is present with " OBDII " name, i select the device from the list and click on yes from the connect popup window message, but it does not prompt for the pin, which is 1234 for the elm327, therefore the connection(pairing) is not complete...

Any ideas? Please please share your thoghts
[MTCB Android Head Units Q&A] TT_Vert:
Have you tried to change the PIN on your stereo to match the ELM BT?

Dave
[MTCB Android Head Units Q&A] oddyutza:
I did, no luck either
[MTCB Android Head Units Q&A] Core-Lokt:
Well, I thought I'd contact AAMP/PAC. They couldn't see the video I linked to from the previous page. Anyhow, this is officially their response.

Clearly, it can be used. I may still try one, but not feeling lucky after the ASWC-1 and the recent attempt didn't work. Thnaks again, all.
[MTCB Android Head Units Q&A] TT_Vert:
I'm still trying to find where I read about someone else w/ a very similar problem to you. I swear it was an amazon review in which he links you to a webpage with his solution. I thought i bookmarked but I don't see it.

Dave
[MTCB Android Head Units Q&A] dureal99d:
I wanted to update all on my progress as relates to the newsmy Carpad III (3). I installed in my 2005 gmc Yukon Denali with bose system. I used the PAC Module # RP5-GM11 interface to retain R.A.P. (Retained Accessory Output) (the factory bose) the ( Factory rear entertainment Package) and this module also retains factory Steering (yes!!! all in one). I am proud and happy to announce that steering wheel controls, RAP, bose amp & RES work. BUt it does take some assigning steering wheel controls manually on your part. When I am allowed to post a video & I will show all I have done and how I did it. But right now which bugs the hell out of me I cant post links, however I will upload pictures. Be advised to all, upon first install you may drain your battery if you leave you battery hooked up. So disconnect the negative battery cable prior to install or it can complicate things. to make the speaker connections I used insulated male and female spade connectors and I performed a throughput test with a multi-meter on each wire, to make steering controls work with chines aftermarket radio's and I mean all as that's all I've used for years, Connect the blue/yellow cable of the RP5-GM11 to the key 1 wire of the head unit though I'm sure your unit has Key 1, key 2 & key -gnd. Nothing else. >>>>>>Key 1 only<<<< wire and turn the steering knob to #7 which is other on the RP5-GM11, as long as you have made proper connections use the key editor of the head unit to assign the keys. Mine has been working all day with no problem's I control all of it with my factory steering wheel. So a now a little educational info for people who need a more down to earth explanation of things as I know sometimes when one is electrically inclined we tend to take explaining things to others for granted, I have read up on a lot of people having issues with steering wheel controls on Chinese aftermarket stereos, Manufactures use analog, resistive and canbus for steering wheel controls on their vehicles, Though I believe 95% use canbus in the united states as this was mandated, I could be wrong , regardless what the pac module does is take those signals and converts them to a language your head unit can understand based upon resistance values. this is why you can hook up a aftermarket Chinese android dash to a newer vehicle and be just fine. I hope this helped explain everything. If you have any question or need tech help hit me up. I'll respond as soon as I can, usually within 24 hours

Also many cables are plug in, so can be extended etc, all RCA on removable harness.

How to install whatsapp? google play said my device isn't compatible (RK3188, 4.4.4. 1024x600)

thanks
[MTCB Android Head Units Q&A] royalhawk2002:
I think Whatsapp need a telephone module to work. You should try installing the xposed IMEI changer module from the Google Play and replicate there the IMEI from your smartphone.

Hope it helps

[MTCB Android Head Units Q&A] agentdr8:
It really depends on the chipset of your adapter, and whether the headunit supports it. By default, the device name has to contain the letters "OBD", so if yours doesn't show up this way when scanning for new BT adapters, then it won't work.

I built functionality into XposedMTC to override this naming limitation, but unfortunately the module isn't working (yet) on the newer firmwares. But even once it is working and can accept/override the naming limitation, the adapter may not work. I've found that's best to have one that uses a v1.2 or newer ELM327 chipset. Most of the modern ones sold today are v1.5.
[MTCB Android Head Units Q&A] TT_Vert:
I didn't have to do much of anything to pair mine. What is the pin of yours? Does your HU PIN Match the ELM327?

Dave
[MTCB Android Head Units Q&A] Jas0n88:
So its not about o/s compatibility. I'll do your suggestion. Thank You.
[MTCB Android Head Units Q&A] TT_Vert:
Please report back on if this works. I've changed IMEI before w/o any result but i'd be curious how it goes for you.

Dae
[MTCB Android Head Units Q&A] oddyutza:
I believe it's 1.5

Name is OBDII

Pin on the HU is 1234( same as obd )

No luck so far with or without xposed module for obd... I'm using malaysk latest firmware
[MTCB Android Head Units Q&A] TT_Vert:
Its got to be that version of the ELM27. Have you tried to connect to your phone to see if it works? If so, is your bluetooth on your phone off when connecting to the stereo? I had an issue where my phone was pairing./connecting before the HU.

Dave
[MTCB Android Head Units Q&A] Jas0n88:
It doesn't work :(

Then I downloaded apk from somewhere else and do offline install with success
[MTCB Android Head Units Q&A] Core-Lokt:
I'm a blue-collar tradesman, so I really don't know much about this stuff. Pardon any illogical/inapplicable stuff as I relate my experiences with BT adapters.

First, I got one of the cheap blue ones. In earlier Malaysk ROMs, it was recognized and paired, although it never would allow Torque to see the ECU. I finally gave up on it and got a BAFX 345t. I plugged it in and it wasn't allowing a password to be entered. In the app Device ID Manager, I saw there was no BT MAC address showing (Malaysk 04/23/16 3166 1024X600 ROM). I manually entered it, and Voila! Now I could pair, as the BAFX already uses "1234" and is seen as "OBDII".

IDK if this will help or is applicable, but I hope you get it working. And if your adapter is one of the costlier ones like Kiwi or ScanTools, I read on Joying Blog about those having issues with these HUs. I don't recall there was anything in particular mentioned.
[MTCB Android Head Units Q&A] oddyutza:
What do you mean by " device id manager " sound interesting

@ tt_vert : device is working with an android phone and tablet, as the time i tested with the HU , de elm was not paierd and it was free from other devices

Thanks
[MTCB Android Head Units Q&A] Core-Lokt:
Xposed Device ID Changer Pro

This is when I first plugged in the BAFX adapter; you'll see it was recognized.

But it wouldn't let me enter a pass code or connect.

And this is what I saw in ID Changer.

I'm guessing even if the adapter was recognized, if the HU couldn't see the MAC address, it wouldn't complete the pairing? All I know is that I have a functional adapter and Torque Pro working.

Hi Dave,

I didn't actually need to send it back. After tinkering with it a little bit more I found that Flashing it with a custom ROM ( I used Malaysk's) helps with the issue.

[MTCB Android Head Units Q&A] typos1:
You need to go into factory settings and set the CAN Bus type fro your car, then an app, usually called "car settings" but sometimes something different, will appear.

There are something like 15 TV tuner types in factory settings, you just need to try them all until you find one that works. Italy has DVB-T so it is on the incorrect setting, you need to pick a DVB-T tuner, not ISDB tuner.

I guess youve got this sorted now, but for full CAN Bus compatibility you need a CAN Bus converter from the manufacturer of your head unit, so it can properly communicate with the MCU and the car.

Not true - the manufacturer can supply you with the original ROM, most are listed on Alibaba and can easily be emailed.

You are in the wrong thread, try the AN21-U thread.

Its actually mini USB, not micro USB.

A simpler way is to look at the settings app - if its a 2 pane app with settings on the left and another pane on the right then its 1024x600, if there is just 1 pane and you have to touch the setting to get into the box to be able to adjust it, then its 800x480.

Please post in the Newsmy section - this forum is for MTCB head units only, therefore no one hear can offer you help and you can offer no help to anyone here either because you have a totally different head unit.

No, Pumpkin sell units manufactured by Shenzhen Klyde, Joying is a seller only, they sell units manufactured by Shenzhen Joyous.

No, they are NOT made in the same factory - we have known for over 2 years that there are at least 8 different manufacturers of these units - check the wiki fro how to identify who makes your unit.

Booroondook's ROM can do this apparently (I read it on 4pda.ru using google translate), try the "Interesting ROM with FUSE support" thread.
