An Improved Carservice app?

Hey agentdr8, been following this thread for months now. I have accomplished everything I really wanted with my unit, except a few extravaganzas, like pairing a bluetooth gamepad (ie: Nyko Playpad Pro), and some other minor things. These discussions here are like my alternative food source right now.

Your work, by the way, is really worthy of praise, as well as your commitment to this thread by helping others.

Well, one of the greatest features I can think of, considering the daily use of my unit (KLD), would be the ability to control multiple media apps with my SWC. Would it be difficult for you to, let's say, tweak the 'carservice app', although I know it's not actually you work? My idea would be adding more apps to the roster, like MXPlayer, TuneIn, and any other really. It would be like adding an initial layer in order to verify which app is active (ontop) and then pass the proper commands. When unable to detect the activity of any of the other media apps, the 'carservice app' we all love would behave just like it does now, meaning it would invoke/control PowerAmp.

What do you think? Possible?

Thank you in advance.

This is my unit: http://m.tmart.com/KD-8008-VW-8-Car...2.2-System-GPS-BT-iPod-ATV-Black_p269588.html

I wouldn't buy from there, like I said I'm missing the GPS antenna and remote control, and no GPS tf card was included. It can be had cheaper on aliexpress.

I can confirm my radio issues are fixed 100% with the klyde. Not a single flaw so far. Radio/GPS mixing also works better, I didn't have to change any settings and FM radio + Waze works fine. On my GS unit, the radio app overrode system audio. I'm convinced Klyde is the original manufacture and the others stole the software, but it doesn't work quite as well on the other hardware implementations. Klyde is the way to go!
[MTCB Android Head Units Q&A] NeoIsrafil:
Thanks Skitals.

Been messing around with the google now that was (apparently) installed by the factory. (yay me for failing to notice the app, lol) So far I haven't been able to get it to voice dial, but I'm guessing that's cuz I left my phone in the house and google knew there was no phone connected. I'll try a proper test later on my way to work. So far it doesn't want to open any apps...but I remain hopeful. Funny thing, in play store google now shows it isnt compatible with the device, even though its installed. Not sure how they pulled that one off.

Did anyone connect it without a converter box? They insisted I'd need one, but with those canbus settings in the factory menu I'm not so sure I believe it. I would think the unit itself would be able to do the translation...

Grasping at straws I guess, just trying to figure out the mic buzz/static.
[MTCB Android Head Units Q&A] agentdr8:
The headunits don't talk canbus natively; they rely on an external encoder/decoder box.

You can always reinstall purchased apps to your devices as long as you use the same Google account in the Play Store.

I'm still waiting to hear back from KeiserSozeyFr regarding the Car Service code. If he's willing to share it, I can extend its functionality. Otherwise I can just build something from scratch. It'll just take more effort and time.

You mention SWC control over multiple media apps. I'm guessing you're using a Mode/Source button of sorts? That would tie in better with XposedMTC since it can already replace the modeswitch method. I have it on my to-do list to add more "slots" to the mode switching so people can add their own apps into the rotation.

[MENTION=2928142]Skitals[/MENTION]:

1 Does it show station name in preset buttons ? (RDS)

2 Is the radio sound with enough treble or is it dead-sounding/muffled (compared with mp3 sound) ?

3 Which car do you have ?
[MTCB Android Head Units Q&A] NeoIsrafil:
Thanks agentdr8,

Tried a test on the google now functionality while the car didn't have wifi...no dice. It basically does nothing. So the search continues for a viable voice dial. If the wiki is accurate the bluetooth functions for the phone connection are handled by an external bluetooth controlled by the MCU...which means that the "bluetooth" app is basically as good as we're gonna get it until we get either a new update for it that includes a voice dial or someone manages to find a way to overwrite it with something better. That is, of course, unless there's something I don't know or get...which I imagine could easily fill several large volumes in relation to these units. Here's hoping there's a genius programmer out there with the interest and equipment needed to accomplish such an undertaking.

Beginning to believe that the mic feedback I'm experiencing (electrical whine and sometimes the sound of rushing water) is something to do with the way the unit handles noise cancellation and reverb control. Perhaps mine is slightly faulty.

I forgot to mention, my mcu version is MTCB-KGL4-V2.01 . Model shows S07. Not sure where I should go to update (if i should even try), but if it adds more functionality while retaining its current I'd be game for giving it a shot.

So far, the unit is functioning admirably despite its problems and my shortcomings. The added functionality that it has provided easily outweighs its faults. I'm convinced with further research and customization these are the best, most flexible, head units on the market.
[MTCB Android Head Units Q&A] typos1:
ptclabs reported a few pages back that GS and KGL units have more bass with the KLD firmware, others have reported improvements in everything, including sound quality.

Yeah ? I was too, mainly because Klyde posted youtube videos of theirs before KGL/HuiFei

They sideloaded it.
[MTCB Android Head Units Q&A] Skitals:
1. Yes, RDS works.

2. Yes, good call, it is dead-sounding/muffled. I set the factory amplifier to Custom and set treble pretty much all the way up and mid and bass pretty much all the way down. Sounds much better that way, and I can adjust the Poweramp EQ to compensate for MP3. This is a very disappointing discovery, but atleast the radio is usable, my GS the radio was completely untolerable.

3. 2011 VW GTI

I also noticed, as other Klyde owners have reported, button backlighting is always on and only red. On the GS the button lighting turned on/off with the rest of the dash lights. Perhaps this is a wiring issue from the canbus converter? Illumination should be a canbus function.

I believe the unit was shipped with software v1.96. Any notable improvements with the newer software?
[MTCB Android Head Units Q&A] typos1:
Um, oh, disappointing, my Klyde unit is on its way to me. :(

Someone deffo said that their KGL or GS unit had an improvement in sound quality with the KLD firmware

My Klyde unit was only available with green - they do do different colours, you just cant change them like you can with some KGL and GS units. RoadMaster dont do RGB LEDs either.
[MTCB Android Head Units Q&A] ptclabs:
That would be good if he shared, or even if he just shared how the two buttons work. The car service app has many problems to work out such as starting everything for playback when a call is disconnected so you will have ilove radio, radio,and whatever is on the SD playing over the top of one another.

Changelog

Hello,

Anybody know where can i found the changelog of each release of firmware ?

ty :)
[MTCB Android Head Units Q&A] Charles83:
I mean that using the right SWC I can not reach any audio menu, so I do not have radio info displayed on my dashboard.

Can you please tell me which FW and MCU are you using? Is it possible to flash only the MCU without changing the FW?

last thing, how can I install exposed? I tried to follow the guide at the beginning of the post but seems that root manager 2.1.1 is no more available.

Thanks a lot for your patience.

Carlo
[MTCB Android Head Units Q&A] zorantoma:
the audio menu is limited to frequinces only on my car display.i just scroll left or rigt with the right SWC. I'm on KLD 2.0.3 FW and KGL 1.77MCU.

For the xposed framework just search on XDA forum for the apk and install it normaly as any other app.

If you don't find root manager till tomorow,send me a PM and i wil post it for you on sunday when i get home.
[MTCB Android Head Units Q&A] Reptile-X:
Root Master 1.3.6

I am using Root Master 1.3.6 guys, the newer version 2.1.1 didn’t work on my unit.

Anyways here a how to install quote from where I got it while ago:

Disclaimer: If you brick your device for some reason, I don’t take any responsibility for caused damage while using this file.
[MTCB Android Head Units Q&A] george2350:
I prefer the 1.3.6 too over the 2.1.1 - both worked for me but then 2.1.1 installs a totally different SU application and the for some reason I feel more comfortable using the 1.3.6 version.

Have a look there: http://www.technologybell.com/best-free-calling-and-texting-apps-for-android/
[MTCB Android Head Units Q&A] agentdr8:
Would the AOSP Messages app normally work in that situation? You could try pulling the one from CM10.1 and see if it does the trick.

I don't know if you'll find anyone that's accomplished what you're after, so you might have to be the guinea pig.
[MTCB Android Head Units Q&A] Skitals:
I might have to take back all the good things I've said about Klyde. Drove home last night in the rain and my FM reception was absolute #$%#. Sounded as bad as my GS. Today, bright and sunny the reception was much better, but not perfect. With my stock radio the reception has always been flawless, rain or shine. To add insult to injury, tmart offered a $2 store credit towards a future purchase for the missing GPS antenna and remote control!!!
[MTCB Android Head Units Q&A] typos1:
Oh, it gets worse. :(

Wonder what it could be ? Static from the rain maybe ? The moisture in the air cutting the signal, maybe a ground loop isolator or booster would help ?

The aerial and remote are obviously Tmart's fault, were they mentioned in the listing ? If so its not as described so if Tmart doesnt have a dispute policy how about your credit card's ?
[MTCB Android Head Units Q&A] agentdr8:
I posted another beta release of XposedMTC to the repo. It now has the ability to automatically set the dimming start and end times based on GPS location, timezone, and current date. In order to auto-update, it runs a service. The location updates will only occur after every 30 minutes and 50 miles have passed since the previous update. While we don't have to worry about battery life conservation on these headunits, I figured the sunrise/sunset times for an area don't change that drastically, so there's no need to calculate it more frequently.

To enable the service (which loads on boot), enable Dimmer Control and Auto start/end times in the preferences.

Thanks to Mike Reedell for his excellent sunrisesunsetlib java library.

EDIT: I realized after some testing that the dimming isn't working with the auto setting. I'll fix it and push a new version up tomorrow.
[MTCB Android Head Units Q&A] sprfly:
Has anyone taken the plunge and got one of the Joyous units yet. I think this a JY MCU version. If so what are your experiences? Thanks.
[MTCB Android Head Units Q&A] Flieger84:
Yes, you can install it again. You have to buy each app only one time. You can use your apps on all units, using your google account.

Which Viper 4 Android version did you use?
[MTCB Android Head Units Q&A] Orannous:
How do you know about the new KLD version? does it get posted somewhere?
[MTCB Android Head Units Q&A] kavo77:
Any update on connecting bluetooth device via terminal?
[MTCB Android Head Units Q&A] Orannous:
steering wheel key mapping

I was wondering if anybody has been able to use the "Steering Wheel Keys" option inside the setting for KLD. It's suppose to allow the steering keys to be remapped to various tasks, but it doesn't respond to any pressed key on the steering wheel (not even the ones that are working). At the same time, vol up/down next/previous and Source on my steering wheel works with the unit. Any ideas? Thanks.

This is to see if I can program the answer/end phone buttons on the steering wheel to work with bluetooth app.
[MTCB Android Head Units Q&A] pakidermo5000:
Hi,

first thing is that your xposedMTC is great. Excellent job.

I have a question though. I set up a auto-dimm task my self quite a long time ago. It basically starts at boot and is active at the times I decide (20-08). I progressively dim out and in (night and morning). My task is calling to a server to get the sunset and sunrise times according to gps position every 5 days, so that the dimming starts and ends at the proper times of the year..

So, basically my task is doing the same as the new module you created. But, since I installed the xposedMTC that had the dim option (I do not remember which version it is) I have noticed that my tasker does not work properly. I have had always the module unset and I kept using my tasker.

My question is, is the module intercepting any dim call, eventhough it is unselected on the xposedMTC? It would explain that the task is not working anymore.

cheers !

They say kld but it is not in the mcu !

Is it really klyde ?

Android 4.4 and a really quick boot time !
[MTCB Android Head Units Q&A] Thiramisu:
Do you mean this Firmware?

[MTCB Android Head Units Q&A] genius312:
So it really is klyde ?

Because the boot time is amazing !

And beside the cpu (a8 instead of a9) and ram 5(512 ddr2 instead of 1gb ddr3), the rest look perfect !
[MTCB Android Head Units Q&A] that_dood:
I am trying to put music on a USB stick. I have a kld, and it mounts it in the storage settings, but when i try to find it in root explorer, or poweramp, it just sits there thinking. I can't access it. Does anyone else have this issue? or any ideas of what I can do?

http://www.ebay.ca/itm/Android-Car-...Video_In_Dash_Units_w_GPS&hash=item2a2fe8d8f0

That is the unit I have, and I have tried the back usb, and the front usb. Same issue.
[MTCB Android Head Units Q&A] staneb:
I just got mine, also for Mazda6 but I have BOSE. If I use back USB, shown in File manager as USB2 (the label on the cable says 3G, WIFI), it doesn't work either. Music app freezes, copying files from USB to SD card is not possible. But front USB works just fine, it's shown as USB1. I did an update to version 2.03 (MCU + UPDATE) maybe that resolves the issue with front USB.

I wanted to copy large file (200+MB) from USB connected to back USB port to SD card, where I noticed that after a few seconds of copying, the light on USB stick stopped blinking, turned off and then turned on again, no more blinking after that. What I understand, this means that USB got unmounted during the copy process and remounted.

One question for you, do you have 2 SD card slots or just one? Because I found just one (GPS slot) and the description says 2 slots!!

Sound output is also very loud and there is a constant hiss present. Maybe this is a ground loop issue, don't know yet. I tried attaching a wire from the case of the HU to the car frame but didn't help. So I guess the housing isn't attached to ground or there is another issue causing the hissing sound.
[MTCB Android Head Units Q&A] agentdr8:
I think I had the default values set incorrectly. I've changed their defaults to false if unset so it won't enable the dimmer control when the switchbox is off.

I'm upping a new beta now.
[MTCB Android Head Units Q&A] Reptile-X:
I downloaded 1.2.7b couple hours ago with GPS auto dimming and it works good :good: didn't past midnight here by the way so I was waiting till than and report back, do I need to upgrade now to newer version?
[MTCB Android Head Units Q&A] agentdr8:
Yeah, you'll want to grab 1.2.7g; I found some issues relating to the preferences file permissions that were causing problems and spent some time today squashing bugs.
[MTCB Android Head Units Q&A] Reptile-X:
I installed 1.2.7G after your post and waited till midnight 5 minutes before 00:00 start the car and the light didn’t go back to higher brightness, I like to thank you again, the auto dimming was a really must for me and it is working great now with GPS calculated sun rise/set.

Have a beer from me :)
[MTCB Android Head Units Q&A] kwalsh24:
Quick question, I have my illumination wired to constant 12v so the buttons on my radio are always lit (done before the firmware did this) will the auto dim work correctly or does it sense the illumination being active thus causing the auto dim not to work properly?
[MTCB Android Head Units Q&A] agentdr8:
XposedMTC dimming will override any dimming done by the illumination wire.
[MTCB Android Head Units Q&A] kwalsh24:
Perfect thanks,

Edit...

Installed the latest version up on repo, doesn't seem to dim my screen any via GPS or non GPS. Will reboot the device and see what happens..

Edit...

Reboot seemed to have done it, guess doing the initial reboot after update of xposedmtc wasn't enough.

Also the gpsmixinfo app, force closes on launch

Doubt

Hello,i just installed the Huifei,thanks to this thread!!

Looks good,except one important doubt. The Huifei always stays on, with the original radio when i remove the key the radio turned off

But the Huifei remains on,i just cant turn it off manually,but not completely off just in stand by

I really don´t know how to fix it and it can end of the battery :(
[MTCB Android Head Units Q&A] kwalsh24:
Take a look at the wiring harness, if you have a 2 wire connector (believe its red & orange wired), disconnect this plug, as having it connected will have a constant 12v power running to the head unit making it so it will not shut off by key or canbus
[MTCB Android Head Units Q&A] grumetecap:
It´s one plug with a silver sticker which says "this wires doesn´t need can bus"?

Red a orange wires
[MTCB Android Head Units Q&A] kwalsh24:
Yes, that would be it, as that over rides any on/off switch in a canbus system
[MTCB Android Head Units Q&A] grumetecap:
Yes these are,confirmed,I disconnected and now works correctly,Thanks a lot kwalsh24 :good:
[MTCB Android Head Units Q&A] RoBe30:
Is there a way to disable canbus steering controls. I need casnbus to activate my digital amp. My car has wiring for both can bus and normal swc. However I have to disconnect the normal swc due to the two conflicting with each other. They got the next track and previous track buttons backwards in the canbus controller.
[MTCB Android Head Units Q&A] typos1:
It may well be a Klyde, they make other units, including Win CE ones, but it is not a Rockchip RK3066 unit like the ones in this thread, it uses a Samsung chip as you noted and therefore isnt relevant to this thread.

Its a common problem with Bose, you need a ground loop isolator, there may even be one for your car, several people have had this problem, its mentioned in the first few pages of the thread.
[MTCB Android Head Units Q&A] that_dood:
Yah, description said 2, but only one for gps, and its the only thing i can use to put music on. the other usb ports are useless.

Microphone for using phone

Hello,

I am using an external microphone to use my phone with bluetooth

Problem is i can ear perfectly my contacts but thy cant ear me clearly

I tried with the internan microphone and it is yhe same

I updated my systeme with version 2.03 but it is the same

Has anyone a reason for?
[MTCB Android Head Units Q&A] elcolombia17:
I was able to make a mixed rom based on kgl 2.03 with bluetooth app from kdl 2.02, custom build.prop, custom music app(first page on forum list in background) remove, for me, unneeded apps, add dimmer app, mod on oem.img to have all new app i will want ready to install. But i have 2 things im no sure how do.

First, remove first image splash, i hate it

And second, add, a good equalizer app like system app, because viper4android no work all time. I had tried all ways and only works with one song and the off until reboot

Anybody works fine with viper4android, for me, impossible

If any, tell me steps
[MTCB Android Head Units Q&A] minhangre:
So I've got an HuiFei unit on my Opel/Vauxhall Corsa C post face lift (with CanBus), and it works flawlessly.

I've also got a rear camera for it, but I haven't got the time to install it yet.

I have the 1.86 MCU and the 2.03 Firmware. I also rooted the device, installed XPosed Framework and XPosedMTC. I haven't tried the auto dim function tough, the one that uses GPS.

I only have a problem as I cannot connect my Bluetooth ODBII device. The HU finds it, but I can't pair it. Has anyone succeeded achieving this?

I would also like to know if there is any way to turn off the screen and still keep the music playing. This could be useful in various situations, as keeping a low profile when you cross a dangerous neighborhood, keeping illumination to the minimum when you are with your loved one in the backseat or even to save battery.
[MTCB Android Head Units Q&A] NeoIsrafil:
Unfortunately I am still having the same issue. Haven't been back to best buy to get them to try and troubleshoot it...

Not sure what the problem is really, and haven't been able to find anything on why it happens, only that it happens.

Just wanted you to know you're not alone.
[MTCB Android Head Units Q&A] edding7:
The electronics of microphone is extremely bad.

Try to make a voice recording and you can figure out how your friends hear you.

Thats the worst thing of this unit and you can't fix it by software.

I think it only can be fixed changing the preamp section. I have enough time, one day i will do it. That's a lot of work and you void the warranty but anyway the mic is unusable.

Even can't work well with google now voice recognition
[MTCB Android Head Units Q&A] typos1:
The best external mic to use is a Parrot one, apparently.

Its also better to disconnect the internal mic as well, use the thread search on the right for more info, its been discussed several times in this thread.

Really :)

It is the right CPU, but this is not written HuiDei, Klyde, Roadmaster, KLD, ect ...

Does that mean as long as it is Rockchip 3066, this is a good one for us ?

Because it seams there is no way to ask question to the seller on Aliexpress ....

Because this one also seams to be a good one ! http://www.aliexpress.com/item/-/1948364463.html

Knowing that all the unit with A9 rockchip 3066 are good and relevant to this thread (rootable) would help a lot of people for choosing one !
