Open the unit. Unplug both ribbon cables and plug them back in tightly. White screen problem should go away.

Installed a reverse cam on my manual car yesterday. Connect the reverse light positive wire to the purple 18 wire on the unit. As soon as you put the car in reverse the camera should turn on within 1 second.

RDS bugs

I've noticed a bug on radio RDS system: when AF is on, the radio jumps to a near radio station when the signal of the current station become poor. In theory, It has to search in background the SAME station based on RDS data and when it finds the new freq, it has to move to that one. But in that case it is not happening; it moves to the next station it finds, not the same like the first one...

I will make some tests with AF off (I didn't have time).

Maybe tha'ts why something strange is happening: when the radio is auto-launched after booting, the radio jumps to the next station but is displayed the frequency of the old station and the favourite button is selected as well. If you change manually the station it came back to normal operation but until then it plays one station and displays another frequency...

Does anyone knows how to change colors/theme of radio or bottom launch bar? Can be installed others radio or music apps without root?

Bluetooth Music and FM/AM radio are controlled by the MCU. (Not the Android CPU).

They need a custom app to make the android CPU talk to the MCU chip which then controls Bluetooth and the radio. If you download an app from the google Play Store it will not know how to work with the MCU.

If you copy mp3 files to the android storage, then you can use any app from the Play Store to play the mp3 files. It doesn't need to talk to the MCU to make mp3s play.

Another doubt... Is it possible change button's led color?
[MTCB Android Head Units Q&A] JS viper:
Open the top cover and you will see the onboard antenna, it is in top right corner of the screen from inside ofcourse.

Solder a cable on it..... not to long, 10cm it is ok and it must be insulated.

But.... the better way is to connect the unit with your smartphone Hotspot.... so you don't have to strong up your signal.
[MTCB Android Head Units Q&A] caralvie:
Another option is solder with a wifi antenna bought on ebay. I have several. I suppose it must be solded to "center/internal part" Isn't it?

Hi Guys, I'm trying to root my unit with KingRoot and I'm using the version suggested in earlier posts (4.9.5) but it doesn't seem to work. I only want it for link2sd so that I can manage the available space better.

I have it set up mostly like I want - switched GPS to Sygic, Bluetooth to phone works, Bluetooth music works, mirrorlink works, backup and front-facing cameras work, wifi works, wifi tethering works, TunedIn radio works.

Any suggestions? I run it and it sees the chip, etc., and swirls for a bit, then says root isn't available.

Newly acquired RK A problem

Have just received new RK A??, Double Din, 7 "Android in Car information/Radio system and trying to fathom out the wiring on the bench while waiting for specific cable suitable for JEEP Grand Cherokee. Have identified Yellow and Black as permanent power source and the the Ignition on (ACC) lead. Is there a further essential connection that acts to complete the basic power up as there is nothing getting through to the screen?

:confused:
[MTCB Android Head Units Q&A] MoshPuiu:
For testing purpose you can connect both pin 10 (B+) and pin 11 (ACC) to +12V and pin 12 to GND (or -12V) of a power supply. The unit should start, wait few seconds...

Otherwise connect pin 10 to +12V (always from battery) and pin 11 to +12V who comes from ignition key (accessory position).

Also you have to connect at least one speaker to test the output speakers if you are interested.
[MTCB Android Head Units Q&A] JS viper:
I noticed that this unit is "eating" a lot of power.... my car is out of power in 2 hours of playing with.

I try to power up with a 12v 1.5A DC adapter and is not working.... it needs more than 1.5A.

My older Kenwood works fine with this DC transformer.
[MTCB Android Head Units Q&A] AIVID:
Hello JS Viper

Thanks for the hints as I was about to connect 12v 1.5A DC adaptor that I had saved from some older project. I now plan to use a spare 12v car battery that was originally connected to the JEEP ......and stand well clear.

[MTCB Android Head Units Q&A] MoshPuiu:
I made some tests when I bought the unit and on a radio/music, the consumption was somewhere much less than 1A (not so loud, somewhere at 5-10 volume on unit scale). I don't know how much is the consumption at maximum volume.

But in standby I have noticed that sometimes the consumption was 3.5 mA and sometimes was 7 to 9 mA. Specifications said that consumption in stand-by is less than 5 mA. I do not found the reason for this behaviour...
[MTCB Android Head Units Q&A] JS viper:
I connected to the DC transformer without speakers.... i think it is a big different if you don't have something to take the power.... no matter if the volume is high of low..... after all, the unit is need power only to boot, but i have no boot as well.

So.... my clue is that needs more than 1.5A to turn on (boot up).

Is not starting with 18W ? ..... if it needs 25-30W to start only, it is to much for a car unit.
[MTCB Android Head Units Q&A] MoshPuiu:
Main consumption is from: speakers, display, GPS, RF/Bluetooth/WiFi.

In order to boot up, the unit needs few hundred milliamps and after initial boot, when it starts the radio unit, the display and the speakers, the unit could take some Amps depending on volume of music, GPS and so on.

So, in my opinion, either you have a defective unit or the DC supply is not good. Be sure you use a well rectified and filtered power supply (a switching power supply, like a laptop one) and not a simple DC Transformer rectified... It is not only a matter of consumption but also of a quality of power supply.
[MTCB Android Head Units Q&A] candrian:
Hello to all. Rather than i have tried checking/unchecking this option there is not difference while i'm typing on the keyboard. The beep still exists and in each key type/beep the music also mutes. Also i can't figure out how to disable the sound mute while the GPS navigation is on. To make it more clear when i'm listening to music and i also have navigation on each time the navigator is speaking the music is muted. Is it possible to let it speak on top of the music?

Thank you
[MTCB Android Head Units Q&A] JS viper:
Be sure that you have connect the cable correct.

In case you cut all the power when you turn the key, possibly the unit go to reboot and lost the setting you have made (there is no battery inside to hold it like PC's)

You have to connect the ACC cable to the key, so you give the order to shut down properly, other cables must have power all the time.

I don't thing you can play music and GPS voice together.... but you can mute GPS by close the volume from GPS app settings.

To play both same time, i think you have to modify the unit software.... but you then mess everything as well (phone handset ect).
[MTCB Android Head Units Q&A] candrian:
Thank you for the reply. Well this is effective not only when i restart the unit by switching the ignition key on and off but also when i just uncheck this option and i try/test to type something before i switch it off.

I bought it to a Chinesse seller located in Spain. The rom is Android 5.1 "LG_EN_RK_LY503_HV.... " It has a link to see manual and is from other unit with 5 touch buttons but it works well XDDD

I only checked it with an external 12V car battery. I will check it a little more and, probably, install it this weekend.

I don't know how make a backup of this operating system (in case I need to reinstall it or send it to someone if you want it)
[MTCB Android Head Units Q&A] MoshPuiu:
Could you write the serial "LG_EN_RK_LY503_HV...."?

Hello,

i got 2 questions about this radio.....is it possible to mirror the back sight camera? at my old Xtrons i could change the the view.

Course the back side camera (ca. 10 years old) of my car shows left and right side changed...

By turning the ignition-key the unit shows the 'be aware of watching video while driving' message...even if the brown(Brake) wire is connected to GND or ACC. ...could the time adjusted or canceld completely?

WC2+ and WC+ cables is the Key1 and Key2 cables and connects to the steering wheel.

Anyone have any idea what is the CAN RXD/TXD cables, or what is the use of it?
[MTCB Android Head Units Q&A] caralvie:
These cables are for CANBUS. Some navis communicate with ECU by CANBUS for read all car parameters (speed, rpm, temperature, fails...) but not all navis can do it.

Other options are use a canbus interconexión box (but are expensive) or, connect a bluetooth OBD interface and link it with navi with programs like Torque
[MTCB Android Head Units Q&A] JS viper:
I can't connect it with Bluetooth OBD adaptor.... is not giving me Bluetooth settings.

I have install the Torque but Bluetooth is off and i can't open it from the app.

If i use an OBD to USB adaptor you think is gone to work?
[MTCB Android Head Units Q&A] caralvie:
First you need an app who comunicates by usb. All apps I know are by bluetooth

After this, you must find drivers for android and the cable you have.
[MTCB Android Head Units Q&A] JS viper:
Torque is given you the setting for bluetooth or usb or wifi.

But there is no change to find drivers i think.
[MTCB Android Head Units Q&A] caralvie:
Yes. I was searching and seems Torque Pro can connect by USB.

Check it and... tell us. Other option is phone link (mirror link) with app instaled on phone and connected by BT with OBD
[MTCB Android Head Units Q&A] JS viper:
What abut Bluetooth? .... it works only with the phone hands free app.

Is there any change to add settings for it?

Is possible to work with some extra app?
[MTCB Android Head Units Q&A] caralvie:
You can connect phone by BT with OBD device, and with navi by usb (mirror link). After this, you can see your phone on navi screen, and run Torque installed on phone
[MTCB Android Head Units Q&A] JS viper:
It's not only that.... i need Bluetooth for more things also.

I like to add a bluetooth tire pressure/temp sensors, there is an app for it "SensAiry".

We must find a way for bluetooth settings.
[MTCB Android Head Units Q&A] MoshPuiu:
It seems there is a development on this firmware but I think there are no noticeable changes.
[Non-Touchscreen Windows Mobile Other] kwoodall:
Here are some designs for Neo I would love to see implemented. This is being discussed at the Shadow/Juno forum on Modaco.com

http://www.modaco.com/content/HTC-J...Proposal-for-new-Neo-Shadow-Screens-Programs/

A home screen alternative with the weather showing above time/date - which are also less cluttered than the current design. This home screen should be also shown as part of the MyFaves screen when the Faves are minimized.

My ideal incoming/dialing screen with the image filling the area as much as possible. However the current pictures stored with contacts are too small to make this truly desirable - however it would be really cool if this could be done and the pics stored could be stored in a larger resolution.

Alternate dialing/incoming screens that still follow the Neo layout but use graphics either at the max of the current resolution or are simply pixel doubled as Neo does in Notifications and Text messaging screens.

These could also be done as a separate Caller ID program that hooks into these calls in WM6 and simply reuse the same graphics that Neo is using for backgrounds (although the left side icons would probably be ignored since this display wouldn't be accessible from the Neo interface).

This image shows a Contact Manager done in the style of the Neo interface. It's not actually a plugin for Neo since it's reusing the left side area for contact pictures instead of plugin icons.

This would be the view contact mode of the above interface. The right soft key would bring up the same menu as in contact manager so you could edit/etc this contact from the standard interface. These two interfaces would be the only ones to develop. Of course it would be super slick to use the same types of animations Neo uses in this as well.

Info:

my device is rooted (fully) and my phone consist of Supersu, Nethunter terminal, bcmon, Reaver.

(below are the codes i modified for my device)

The history

when I first started running reaver i would receive many errors; [...not found] [...can't enable] [...can't change permissions (appearently you can't change permissions within sdcard folder... anyways, moving on.)]

[...no internet connection found]

my point is after looking at the custom scripts I had installed (with notepad++) i noticed that the actual scripts were the big issue. so I started changing things one by one in-order to not mess-up everything. yeah sure, I made some errors that made things last longer- way longer than normal. Nevertheless, at some point I actually started making things better and slowly started knocking down those errors!! until i hit the 'test' button and sure enough

"Cannot link executable... libfake_driver.so is 32 instead of 64.... only PIE are supported."

Truth Be Told

as you might can tell from the kind of question I'm asking, I am not an expert.

And I understand these kind of questions comes with others looking at the questioner as annoying- and with the thought of 'these beginners just want everyone to give answers instead of learning themselves...' It's NOT COMPLETELY wrong, since now days a comment like such is ... pretty much true-

So i'll say this: Not Every One Is The Same.

I am a programmer. my programming is mostly within game design/ game development so if more coding is needed to solve my issue at hand, then let me know and please (at the lease) point me in the right direction.

if I need to google something, please clarify what to search. For I am just one person, so it is possible I haven't thought of something to type in- however, that does not mean I haven't type MANY searches in already.

The Question

Am I able to use Rfa and bcmon on nexus 5x, and if so, then what is needed to get my phone operating (the app(s)) correctly? This is the complete error i am receiving in RfA.

CANNOT LINK EXECUTABLE: "/system/app/bcmon/assets/libs/libfake_driver.so" is 32-bit instead of 64-bit page record for 0x7f98e8c010 was not found (block_size=64)

error: only position independent executables (PIE) are supported.

My Done Work

with the rfa settings you can choose to use custom scripts the following shows the scripts i used and it's placement.

these scripts i had to modify to get the device's errors fixed ( not all though )

Activation Script:

#!/bin/bash

svc wifi disable

LD_LIBRARY_PATH=/sdcard/bcmon/assets/libs

LD_PRELOAD=/data/sdcard/bcmon/assets/libs/libfake_driver.so sh

cd /sdcard/bcmon/assets/tools

./enable_bcmon

echo “rfasuccess”

exit

Warm-up Script

#!/bin/bash

LD_LIBRARY_PATH=/sdcard/bcmon/assets/libs

LD_PRELOAD=/sdcard/bcmon/assets/libslibfake_driver.so sh

cd /sdcard/bcmon/assets/tools

Stop Script

#!/bin/bash

svc wifi enable

echo “rfasuccess”

Hi There, we recommend you check to see if any unused apps are still open on the device and to close out of them before going to sleep. You can also try turning off WiFi and Bluetooth if they are not being used while you are asleep. Another recommendation is to clear all your caches.

i thinks its mainly beacuse of more cpu cores online while the device is in idle state.

[Honor 8 Questions & Answers] Godavos:
Hi,

I just got phone and I think I got same problem. When you look battery chart over a day its just downhill, no flat parts to the right. Does not matter is screen on or off, he just drains battery.

So I looked at P9 forum, same stuff going on. And that Andorid himself is main battery drainer. When you look application , over 1 hour, whatsap drais 1 mah, and hangout draing 1 mah , but battery goes down rapidly.

They say factory reset might help because then Andorid resets and stop doing mess.

Also they say if you cut by yourself the sim card to nano, you might cut is slightly wrong and that is causing drain also so maybe get original from operator.

Also if you have memory card, format it, copy data back

Also suggested cpu spy (black one), and GSam Battery Monitor to check deep sleep and aps doing damage.

I'm also starting this journey of battery drain solving and didnt try above. Will post results...

edit: So cpu spy showed that I was getting very very little deep sleep. So I went throught options and disable / unprotect more stuff. There is also option under security about letting services see other service. Disable that also. As I can see you must put under control google play as much as you can. Viber is also doing the damage much more than hangout or whatsup.

The strange thing is yesterday afternoon , evening everything was cool. Then I went to sleep and anfet 6 hours 20% less battery, and again no deep sleep. like Andoird is doing something during night and my backup is disabled etc.
[Honor 8 Questions & Answers] venom007:
