You're right, your sh works really well! I actually use it a lot and thats why I sugest it around :) As I'm remember,in my quote I said that busybox needs to be installed. What is wrong on that? :) Then I said to you that i had issue with busybox not being installed or broken and i came with an explanation :) Please tell me how my suggestion confuses people here? :) Again, don't take me wrong, i respect the work of everybody here and I try to help!

Thank you very much for respond DSA8310

The seller is not cooperative at all. I was taking a foto from my unit with RAM Memory 512MB and he is always shows me a foto from Rom 1GB. My problem is that i did already opened my Unit. I wrote to Jacky , she wants 138USD for rk3188, its high the price for me...I just made swap RAM to SD Card but its not a solution. I have to wait till i find a rk3066 1GB RAM or better rk3188..

But thank you anyway very much, you are all great here...

Hi,

I did a bit more investigation on my unit, was feeling brave today and went poking around with a DMM.

C102 is connected to Pin 4 of the bluetooth card & the white (signal) wire of the external microphone cable. I would also assume that the internal mic is in parallel.

There is 1V DC on the connector/internal mic side of C102 and 0V DC on the other side (bluetooth card) of the capacitor

There is a very good tutorial on microphone connection/biasing on a website called hobby-hour.com but the site won't let me link it.

Given that the supplied external microphone has a two pin / mono 3.5mm jack then then we can assume it is a dynamic microphone that is usually run without a DC bias but which generally requires connection to a preamp on a soundcard ("mic boost" on a windows PC). So probably supplying 1V DC to this type of microphone is incorrect and may cause distortion. I would guess that the internal microphone is of the same type. This probably works just fine with the android system because it will be using a preamp and I know that there is some soft gain that can be adjusted if an app like "Microphone" is installed.

I would guess that the bluetooth module does not have any gain adjustable preamp and just expects a certain pk-pk signal level. So by just removing C102 and connecting the external microphone directly to the bluetooth module the signal level may not be strong enough. So if we assume the input gain of the bluetooth card isn't good enough to use a dynamic mic like this then I guess I need to remove C102 & connect a dynamic mic through a small external amplifier first or just install a 3pin connector and wire up an electret mic with +5DC bias on the ring.

I'll look into it some more, need to order some parts to see if I can sort it.

Hi Leckig,

I have exactly the same problem as on your video.

However mine is already connected to the reverse light but with the ground as well.

When i put the car in reverse I get the image but as soon as I start to move I lose the image.

Connected the following, connected the composite on the radio side to the "camera in" plug and connected the red wire in the same cable to the "reverse" wire of the car stereo.

The other side I connected the composite to the reverse camera composite.

I connected the DC plug to the reverse lights (positive and ground).

The red wire within the composite cable on the reverse camera side I didn't connect.

I thought it is a power issue because before losing the image I can see stripes in the image, like it is starting to break up.

Maybe you can help me out with this.

Hi Antvic,

Did some further digging around on the forum and tried the option to put the canbus on Golf 7 (simple) instead of VW/Skoda setting.

Surprisingly as far as I can see/tested it, it works.

Door notifications are correct when opening, also vehicle info is working and it added an extra apk for the settings of the car which seems to be according to the car.

So thanks all of you for solving the first problem, on to the next,lol.

So I'm trying to work on replacing the install-recovery.sh file and want to be sure I'm doing it properly.. Any one have a step by step written out? I've searched and haven't quite found out a definite way.
[MTCB Android Head Units Q&A] agentdr8:
1. Install a root file manager (ES File Manager, Solid Explorer, Root File Manager, etc)

2. Copy old /system/etc/install-recovery.sh to somewhere safe (maybe sdcard?)

3. Copy newly edited install-recovery.sh to previous location, overwriting it.

4. Change ownership to root:root, and mode to 755 (or rwx-r-x-r-x)

5. Reboot
[MTCB Android Head Units Q&A] ronnieeeeeeeeee:
Great. I have all of that down, except #4. How do I go about changing ownership? I intend to add viper, and car services to the install-recover.sh.. do I just drop those within the edited file, etc. ? Sorry for all the questions.. just trying not to brick. I had a scare with that once before.

Great help from many here. I've gotten all my issues fixed, aside from trying to get all these services to start on boot. (I'm using a Dremel tomorrow to make a dash kit modification, then I will be set) :)
[MTCB Android Head Units Q&A] agentdr8:
Each file manager has a different way of accomplishing the changing of ownership and permissions, so you'll have to search for the particular one you use to find more specific info on how to do that.

As for the edits, there should be examples if you search this thread over the past few days. I know it was discussed recently.

Sygic TTS is way louder than music playing over bluetooth other than the hidden menu is there anyway adjust this as Sygic does not have individual volume control. Also coming from my stock head unit sound quality does not seem to be as good as default. Is this more of a known issue or is it possible I'm having a wiring issue?

Also only about half of the Steering wheel control buttons are recognized. This is a Subaru but has anyone ahd a similar issue in any other vehicle?

Thanks!
[MTCB Android Head Units Q&A] MayfairDROID:
I guessing Sygic is a GPS app? If so, go in to GPS settings on the hu, and adjust the GPS mixing. I had to do this with Waze.

As for audio quality, it is hit or miss, and the only real fix is to install a rooted rom and install Viper. Do a search and there is a lot of discussion on this topic.

Can't help with SWC as it is dependent on your can bus system and not many folks have piped up with Subaru specific issues.
[MTCB Android Head Units Q&A] nFKT:
Sygic is a GPS app yes. I will try GPS mixing in settings though, cheers!

Hit or miss on the specific unit? Or hit or miss on which vendor? I currently have Klyde, volume is a fair amount lower than stock, and some vocals produce a very scratchy noise from the front speakers. The built in amp seems to work much better than Viper Audio.

No canbus support on Subarus. Volume up and down and channel up and down are assignable. However pick up and hangup, the mode and voice command buttons do not seem to be recognized at all. I'm wondering if I pickup a Metra Access that I might be able to rig something up. I will also see if I have any better luck with one of my newsmy units.

[MTCB Android Head Units Q&A] edit:
The saga continues... problem still not solved.

Made the modifications and posted a screenshot with the result, does it look right?

After a few days of usage I've began to see a pattern : Every time i turn off the car the unit saves the last active (on screen) app and usually is it a player (Deezer or PlayerPro or XiiaLive Pro). The next time I turn on the car, after the unit finishes the booting sequence it shows the app (that was active on the screen at shutdown) BUT does not start the Viper4Android app UNLESS I select android BACK button or HOME.

The funny thing is the RK3066 HeadUnit app starts ok each time (also very early) but not the V4A.

Can you please share some ideas?

Thank you

giving you the resources.arsc or the strings file with translated italian pty should be enough to include in the Malaysk's rom or substituting in the KLD style the file should be enough ?

For anyone whos interested, I had a problem where my unit would not play music from my 128Gb USB stick properly - the sound would cut in and out every few seconds. I was going to buy a 128Gb SD card, but theyre very expensive.

So I bought a 120Gb Kingston SSD (for 30GBP, thats less than half the cost of the cheapest 128Gb SD card!!) and a USB to SATA adapter, it works fine - the SSD mounts very very fast and music plays properly at last !! I

Its not as small as an SD card obviously, but it iis very thin and compact, I didnt bother with a case as it doesnt really need one.

Put whatever launcher you want into the system/app folder, you do not need to rename, you do not even need to back up as all 3 launchers are on the fileserver.

You may have mixed me up with the users that upgraded their rk3066 cards with rk3188 with 1024x600 resolution that was distorted. I have the animation hang occasionally like 1 in 10 to 15 boots. My seller sent me a replacement rk3188 card thinking it was the problem. I paid for the card and had the option to return it for credit. It did not fix the issue so it is a good card. Since I live in the US I decided to sell it in the us. Since we now have sleep mode the chance for the hangs is much less. By the way my current draw is only .15 amp in standby.

[MTCB Android Head Units Q&A] MayfairDROID:
DSA,

First off, thank you for all your assistance with these questions. I have learned a lot from you.

I do want to address something that I have seen you and multiple others suggest. I have an issue with telling folks to open a dispute with the seller if the cause of the issues the individual is having stems from them modifying their systems. If the unit worked prior to them flashing the wrong ROM or MCU, then the issue is the individuals alone, and the seller has no responsibility to assist. Using the dispute process taints what what process is actually for; resolving problems that stem from the sellers mistakes (or manufactures). IF we continue to ask resellers and/or manufactures to replace units that we "f" up, then they are going to stop supporting us at the level they are, and then those that need assistance, wont get it.

I think the disputes for factory or reseller issues is a great thing, but to use it because the user took a risk, flashed something they didn't fully understand, and broke their unit, is a bit irresponsible. I know you and the others are not doing this with malice in mind, but the long term consequences could be hard to deal with if we continue trying to force manufactures to fix something we broke.

my .02 :)
[MTCB Android Head Units Q&A] MayfairDROID:
Thanks for understanding I was coming from a good place :) I understand it is on a case by case basis, and that if the vendors supply the incorrect firmware, it is absolutely their issue to resolve.

Ignition issues

Wonder if anyone could help me out. I've bought a 4.4.4 unit.

Model No: S07

MCU Version: MTVB-KLD2-V2.50

Android Version: 4.4.4_14042015

Kernel Version: 3.0.36+

Build No: k3066-eng4.4.4 14042014

CPU: ARMV7 1.6GHZ (x2)

Memory: 1024

Believe the screen size to be the 800 one

It's a Audi A3 Specific one.

The unit doesn't turn on/off with the ignition, nor does it detect where the car is in reverse for the back-up camera.

Anyone have any idea on my issues? The Can-bus boxes is working somewhat, as the steering controls work.

Any help appreciated!
[MTCB Android Head Units Q&A] typos1:
I got a single one without the extra adapter, I did think it may be a problem, but luckily there is enough power with one USB. I got USB 3.0 as its also compatible with USB 2.0, wont make any difference to these units as they are only USB 2.0, but if youve got USB 3.0 on your pc it will be quicker to transfer stuff to the SSD. If you have not got USB 3.0 on your pc, you will on your next one. :)

I am afraid you are mistaken Mayfair, there have been NO instances of anyone on here being recommended to open a dispute with the seller as a result of anything they have done to their units, DSA and I have only ever recommended a dispute if its a result of a defective unit. If someone updates their MCU and it is the correct MCU for their unit and there is a problem, then it IS the seller's responsibility, if they flash the incorrect MCU then it can be reversed by flashing the correct MCU, no one has been told to open a dispute because they flashed the wrong MCU.
