RDS Issues

Has anyone gottent the RDS system to work decently on these units?? I noticed on my daughters car with a stock radio the RDS works pretty decent and legible. On my Klyde it works sometime but the letters are scrambled a lot of the time. Anybody have any experience with this??

Deciding.

All,

I am sorry to post a post such as this, as I know that this can clog a forum up. However, I have read and read and read and I am having a hard time just deciding on a unit to buy.

I don't know which units people are having the most success out of or the most problems out of. I know I may be asking to much, but if it was possible if someone could just PM me or post a list of the best units? I had one picked out last night it was a unit that cost normally $270 and it was on ebay for $100 guy had 4 left. Before I could click the buy button they all 4 where gone....

Anyways if anyone would be willing to post a list that would be great!
[MTCB Android Head Units Q&A] marco.lav:
Thank you very much,

I have a stereo GS, but in the Downloads page, I find:

- KGL

- KLD

- KLD

how come I can not find my model? am I missing something?

Many Thanks;)

You can use any rom variant on any headunit as long as you don't flash the MCU with it.

Default Volume Settings

Can someone with a Klyde HU (Preferably one with an external mic) tell me what the default volume settings for Bluetooth are? I am talking about the settings under "factory settings' where you enter the 126 code. There should be a tab for the different volume settings with adjustments for each. I believe these are the internal volume (almost like line in settings). Trying to track down my bluetooth echo.

Steve
[MTCB Android Head Units Q&A] staneb:
My default volume settings on Klyde with external mic for Bluetooth is 14. No echo with Bluetooth but I use RCA output which bypasses internal amp and volume settings.
[MTCB Android Head Units Q&A] typos1:
Probably cos theyre joined together, see DSA's mic mod for Klydes for how to separate them.
[MTCB Android Head Units Q&A] comptechltd:
Yes, I am aware of the 'seperation' required. Still looking for the 'default values'.

With blank screen after reverse cam activated bug:

I reinstalled the stock KLD-20141223 (Android 4.4.4+2.20 MCU). Worked OK. Than I installed Coudu's KLD_4.4.4_800x480_141223_rooted_light_reparted_init.d_v4.2. I made all settings, installed all apps/services what I use (approx 1 hour), tried revers worked fine. Then I inserted in a CD and the screen blanked again. Reflash just MCU 2.20 helped, but after reverse gear bug comed back. The same effect (blank screen) when turn on headlights.

Now I installed the stock KLD fw. I test it for a week.

The Hungarian translate works fine:D

With Radio-Poweramp bug. With MODE button now shuts down radio, at least on factory display not shown the frequency, but the SWC NEXT/PREV still changes the Radio preset channels. When I go back to Radio starts with other channel than I closed it.

We need the right canbus adapter: for Mazda 3 2004-2009. Klyde sent for newer Mazda 3. This is the problem. I hope they will send to us the right one.

Just the MAZDA&OPEL Simple option works with our cars. The right canbus adapter can handle the trip computer and clock settings, no need for 2way canbus.

I have not received it as I just ordered it. Way I figured if it turns out to be a scam aliexpress has a money back guarantee, and my credit card also has a money back guarantee.

I also figured with this being what appears to be a relatively new seller maybe they are trying to get positive reviews.

It is very very cheap, but with aliexpress' buyer protection and using a credit card you cant go wrong.

Audio Priority on Native apps

In my unit, i use an app called Maparadar that warns you about speed cameras, it runs in the background and plays sounds when I approach speed cameras, my problem is that when I'm listening to radio or other native app, there is no decreasing on volume and i can't hear the warning, and this occured only with native apps, seems that the native apps have a certain "audio priority". (I also use powerapm, spotify, tunein and works great with maparadar and other audio warnings).

I realized that if i put the maparadar app as the default GPS app on GPS configs will solve the problem but when i use WAZE (my default GPS app) the same occured with all waze sounds.

In short, i want to know if there is a way (no need to be an easy way) to put more than one app on GPS Default list. Or ir there is a way to give this "audio priority" to other apps instead of the default GPS defined app.

Does anyone have steps for getting an HSUPA 7.2 (generic) setup and working?

I have a Tmo Sim card with service (BYO Tablet plan with Straight Talk) and when I power the HU up with the USB dongle installed it will show signal bars, but no data connection.

I went into the Data settings with a shortcut from Play store and it will take NO radio modes (WCDMA/GSM/LTE/CDMA) it always goes back to Unknown.

I also get messages in notification drawer saying "data service disabled" and "Voice service disabled" (or something like that).

I am running 4.4.4 but FW version 2.03. Not sure which MCU I should/may need to flash since its listed as a KGL1-v2.03 and there is no "KGL1" version of MCU above 2.03 that I can find.

Should I flash a KGL4 version? Would this fix my 3g dongle issue?

Does it matter what # is after KGL so long as its a KGL MCU img file?

Is there a way to back up the current MCU img? I don't want to try another MCU img file unless I know I can put it back to the current one.

mics

I just took apart my GS and popped out the jumper for the microphones. Ran 2 plugs into the back and plugged in one for the android ran directly to it, and another to the bluetooth card. Other than melting in the GPS wire backwards when i put it back together it went well. I would 1000% recommend this modification to anyone wanting to do email dictation while driving. It understood every word I said, even better than my phone.

The total cost was 3usd.

I did go back down to 4.2.2 until google gets their stuff straight and it stops crashing. 4.4.2 had the volumes fixed for the gps and android, so I am back to the only problems of trying to mess with the factory settings to hear my nav.

[MTCB Android Head Units Q&A] zorantoma:
You can use any of thr 4.4.4 fw. For me 1.77 mcu worked best

Me too. I went all the way up to 2.09 but downgraded to 1.86 .That was the latest mcu that i used where button illumination worked best

But on 1.86 you lose the gps button ,becouse it acts like back button.

Greetings mates!

I have recently purchased an Eonon G2110 (MCTB-JY-V2.08, Android 4.2.2)

I have some questions for you:

* Which cables do you need to connect to make working the steering wheel control? I have two wires from the radio and two wires from my Focus 2005 steering wheel control, tried everything but it does not work...

* How to fix a poor radio reception? I have read on other forums to "hook" the blue wire (antenna amp) from the radio.... but hook.. where?

* I have installed Map Factor navigator free, but I am unable to listen to music or radio while it is on navigation... it should interrupt music when the navigation system speech... or not?

* Doing an update to Kitkat 4.4.4 should fix these issues?

Thank you!!!

Regards

Andrea
[MTCB Android Head Units Q&A] manicuspanicus:
mine is a car specific model and i didnt loose the gps button. On the contrary button illumination was on all the time. Now it follows the car's illumination (lights on , lights off the rest of the dashboard i mean.)

Also i havent noticed any improvement over the various mcu i have tried so far. Perhaps they fix canbus problems etc however i havent noticed anyting on my case. It would be nice to see a list of changes over the various mcu's for a change.
[MTCB Android Head Units Q&A] n3m35155:
Steering Wheel Controls: I hooked up the Steering wheel ground from unit (K-GND I think on mine) to the steering wheel feed gnd and KEY1 to the other wire. May need to go into the programming page in settings to reprogram it.

Radio Reception: I don't have the same model, but I noticed on mine the connection is flaky. Sometimes when I put it back in I have Radio signal, sometimes not. I usually put it in and before screwing it down, test first. No signal I'll unplug and replug it and try again until I get signal. There is a link in OP about how to fix it. Bad solder joint usually at the connector. Look in OP.

Map Factor: Don't use it. I use Google Maps and tether to my phone. I have a 10GB data plan, so no issues there..

Hope that helps!!

[MTCB Android Head Units Q&A] ezekial86:
Hi All,

I have an Erisin ES9746 KGL1.

I am trying to install a reversing camera.

The device has a reverse wire that comes out of the canbus and then goes into the head unit which is disconnected when you get the unit. When you connect it and go into reverse it should put 12 volts through the canbus and into the head unit so that it goes to reverse camera.

For me this is not working and when I use a multimeter I can see that the canbus is not producing any voltage from the reverse wire when the car is in reverse.

I can take the reverse wire from the head unit and feed it 12 volts and it works fine and switches to reverse camera. I can obviously wire the reverse light power directly to my head unit but I would rather have it work as intended with just the wire from the canbus. Does anyone have any ideas on why it isn't producing any voltage?

Thanks!

Thank you, for your assistance. I have tried your instructions but I am sorry to tell you that it id not work.

first of all the pin numbers caused a confusion. The link you sent me shows harness figure which does not correspond to vehicle harness. The main harness has only 14 pins. then there are two side hardness. one of them has 20 pins. when I used the side harness it did not work connecting key 1 to pin 7 and 8. I did not used the ground because is already connected unless there are two grounds which I highly doubt.

Your advise is requested.

I have a Pumpkin (Klyde) unit installed. Used a rooted 4.4.4.4 rom and upgraded MCU to 2.20. So far everything is working. Biggest issue is my Wifi reception is really bad. It has built in wifi I have to be within about 20 feet to get a constant signal otherwise it is on and off. Can a usb wifi adapter be used if so how would that get turned on? Or is it best to crack it open find the antenna wire and add a short extension to outside the unit?

Also have not been able to connect it to my bluetooth ODBII. It shows it in the list but wont connect. Will try another OBDII dongle and see if that makes a difference.
[MTCB Android Head Units Q&A] agentdr8:
If you're trying to connect resistive SWC, there should be key1 and key2 wires, along with a specific ground for the SWC on the headunit harness (sometimes labeled key-ground). This ground should be connected, either to the ground that is found on the vehicle harness that the key1/key2 wires are sourced from, or to the same ground that the headunit uses for everything else.

Unless your OBD adapter name contains "OBD", it won't pair by default.

It does come up with OBDII as the name. I have also tried the XpostedMTC and it still will not pair. When I click the OBDII name it asks to connect, I hit Yes and it just comes back to the screen. Nothing else.

If there is any more information I can provide, please feel free to ask. I will do what I can to help.
[MTCB Android Head Units Q&A] agentdr8:
That's odd. Try pairing this way:

- Open up the BT app on the headunit

- Hit the search button (should look like a magnifying glass I think)

- Wait forever for it to finish populating the list (which might only show 1 thing, but the spinner will take ~60 secs to disappear)

- Tap once on the OBDII device in the lower list

- Hit the pair button (should be the one under the search button IIRC)

It shouldn't prompt you or anything. If it's successful, it should move the OBDII device from the bottom list to the top list.
[MTCB Android Head Units Q&A] BrownHP800:
I did that too. When I hit the pair icon it does nothing.

I think there must be some incompatibility with my OBD adapter. I can pair to it with my Galaxy S4 so I do know it works, just not with this unit. Gonna try my son's adapter, it's a different brand and see if that makes any difference.

I have successfully paired to my Galaxy and my iPad (not at the same time though) so I do know the bluetooth is working.

Has anyone else had any issues with the screen backlight?

I bought a vw specific unit that came with the JY 2.16 MCU. The unit has an 8" 1024 x 600 lcd. The backlight appears to be on but it only visible in low light. Any sunlight makes it impossible to see the screen and the brightness does not brighten or darken the screen. It though it appears to flicker a bit if slid all the way up.

I tried downgrading to the 2.11 MCU and installed a different rom, but they did not fix the issue.

Same problem whether connected to car, or computer psu.

I opened the unit, all cables appear to be connected properly, although since it's an led backlight and not ccfl I'm not exactly sure which board/cable is responsible for driving the backlight.

Any ideas what the issue could be? The unit functions fully otherwise, including the rgb led capacitive buttons which correctly turn on and off with my headlights.

with version 2.08 problems were the same.

Tomorrow I try again to put it all over again and see what happens.

As regards the radio:

- All chip tuner are controlled in i ^ 2 C.

* The command that we should give it is an i^2c command.

* I do not know who controls TEF 6606 or similar (example TDA 7706)

I think the management is left to the MCU that has control of all hardware devices of UH.

all radio tuners have two receivers interiors,

one for transmitting to the radio, and the other to find the alternative frequency.

only that the management is bad.

this is a pdf of TEF 6606 Please see the 3° page

pin 4 --> FM in 1

pin 3 --> FM in 2

if anyone knows how to control it, I wish I could help!
