[MTCB Android Head Units Q&A] typos1:
I know thats what you did, because you said in your post, what I suggested in my reply is that you check the the ANTENNA is actually connected - so, for the second time, have you checked that the antenna is actually plugged into the radio IC ?????? - the radio IC could be getting all the power and grounding in the world, but it aint gonna be getting a signal if the antenna cable inside the unit is not plugged into it !!!!!!!!!!!

I compiled the data for the pdf and I never used that word, in fact it isnt a word, there is "tiramisu" - an Italian desert, but that really doesnt make any sense.

The GS units could be called "frankenstein" or "mongrel" units or some word that means "mixture" or "crossbreed" or a similar word, as the GS units appear to have elements of both KGL and KLD components.

I cant find any mention of "thiramisu" in the pdf.

But taking "tiramisu" and adding an h doesnt really make much sense . . . unless its an Australian thing ! ?

These headunits aren't just phones/tablets slapped onto a double-din frame. They have additional hardware that most likely isn't optimized for power saving, as you don't normally have an amp IC or MCU to deal with in those portable devices. Sleeping the android portion of the device may not put those other components into a low-power state (assuming they even support something like that).

Thanks for the widgets.

Any chance you can do a version of this post:

from 4pda.ru on XDA for all of us in this thread ? - not all the links work and the Google translation isnt very good.

And maybe add some screenshots of your firmware ?

It is very frustrating trying to read the thread on 4pda.ru - there is so much stuff you guys have done that would be useful to know, but the translation is so bad that a lot of it I just cant understand :(

hi all, I bought one of these units :

http://www.ebay.com.au/itm/Android-...-/281463096297?ssPageName=ADME:X:eRTM:AU:1123

it works well and I have generally happy with it but was hoping someone can answer some questions.

1. There is no subwoofer volume control. I have external amp with sub hooked up to it and its bit quiet. My previous Android HU had a slider for subwoofer output which worked great. Is there a software I need to download to do this ?

2. What equalizer app would ppl recommend for this HU ?

thanks in advance
[MTCB Android Head Units Q&A] typos1:
Cant remember all the ins and outs, think you re-format the card in fat32, but you ll probably need some software for Windows to do that as Microsh*t have imposed a low limit for fat32 to encourage people to use their newer exfat format. I use Linux, so I can just re-format with no probs, the same for Mac users.

Dont think you need to do anything to the Android side of things - Android is a type of Linux so can read fat32 up to 1 Tb. A quick Google should confirm it.

Thats one of the new "JY" units.

Viper audio or Poweramp are what a lot of people use.

As for the woofer control, the AN21-U has sub volume adjustment I think - the amp IC is controlled by the mcu, there is a post on4pda.ru about connecting Android directly to the amp IC to gain more control, but Google translate doesnt work well enough for me to work out exactly how to do it, Iv e asked Booroondook (who is on here and 4pda.ru) for more info in my post on the preivous page, but hes not replied anything yet.
[MTCB Android Head Units Q&A] anewoasis:
I have gone to that website through chrome and still not found anything that said how to add control over the subwoofer.

http://translate.googleusercontent....st=420&usg=ALkJrhhrJT7hDMK5gwRbAkwoPdHYKyiOsA

Second entry under the heading "hardware improvements" in the list at the top, gives links to 2 posts about giving Android direct control over the amp IC, as I said in my previous post. But doesnt appear to say how to do it, which is why I asked Booroondook about it.
[MTCB Android Head Units Q&A] anewoasis:
I read that thoroughly. It is not talking about doing it through a download of a MCU or any program. It is talking about bypassing the control and soldering your own so you can control it manually (at least from what I could understand). That is way too advance for me and probably most users here. Also I can imagine your warranty would be voided by doing something like that.
[MTCB Android Head Units Q&A] omarko:
thanks, I installed Poweramp (bought the pro version) and changing the equalizer settings or pre amp does nothing to the sound. Any ideas why ?

I also have a bmw e91 2007 without gps and automatic ac . I would love to buy a radio android . Preferably in Europe. I found one seller,he has items to sell on ebay but the official page is slightly cheaper .

Anybody can give feedback about radio and if the seller is trustworthy ?
[MTCB Android Head Units Q&A] typos1:
Yes, I know know what it says !

I did say it was "connecting Android directly to the amp IC", by definition this would involve soldering a wire, I didnt say anything about it being a software mod, plus its under the heading "hardware improvements" !!

---------- Post added at 11:23 AM ---------- Previous post was at 11:20 AM ----------

Dont know I m afraid, it works on mine, well, the master volume worked on mine, I didnt try anything else and after 3 days it said I had to buy the full version, even though the trial is supposed to be for 15 days. Maybe you have to be rooted ? Are you rooted ?
[MTCB Android Head Units Q&A] kwalsh24:
I wish they would make it so you can adjust the sub out line, I ended up plugging my sub feed into my rear speaker line out, as my sub kept kicking on and off with the sub line...

Wish 3rd party eq's would adjust the built I'm apps, I'm using the auxiliary in and it has next to no bass vs the music & radio apk. I havr my sub next thing to cranked, that's the only way I can get anything out of it. If there was another android HU similar to this unit with adjustable sub control & a higher res screen, id likely ssell my unit for it.
[MTCB Android Head Units Q&A] Skitals:
I believe there is a button/toggle on the equalizer and preamp screen to actually enable them. See this image, make sure Equ and Tone are lit up: http://powerampapp.com/wp-content/themes/poweramp/images/big/eq-1.jpg
[MTCB Android Head Units Q&A] typos1:
Yes, its the AN21-U that has adjustable sub settings, its a pity this one does not, but in most other ways its better than the AN21-U.

Have you gone into factory settings and increased the Aux-in volume ?

You could get an amp and wire that in, then youd be able to adjust the sub gain and probably get better sound quality overall to boot, you could also maybe get a pre-amp for the sub or a small device to increase the gain for the sub out - some factory amps do not have line in connectors and need a small box to step done their voltage, maybe try one of these in reverse or something ?
[MTCB Android Head Units Q&A] kwalsh24:
Yeah, the an21 would be great if it had more power and a better screen haha.

I have the settings cranked to o bileve 20 in the factory settings, and to be honest I didn't even notice a change.

I have a jl audio amp running a shallow mount 12" sub that's installed in my spare wheel area, worked great on my last 2 hu's. Just this setup here, not so much. I also find that the aub only really does anything when the audio is past the 15 marker, anything before that its hardly on.

It just be nice if the manufacturer would allow a bypass for the stock eq, and allow apps to modify the sound produced by the apps. That would make this unit even more awesome lol.
[MTCB Android Head Units Q&A] typos1:
Yes, there is the mod someone talked about on 4pda.ru that I mentioned on the last page that gives Android control over the amp IC, but cant find out exactly how to to do it.

Has your amp not got settings for sub gain then ?

I m using a factory Bose set up that takes 4 channels and separates the sub itself, a fair bit of base does go to the speakers, but I m happy wth the sound.

I did have problems with the sound level though - the RCA outs of these headunits is 3V and my amp needs at least 4V, sure enough the sound did not go loud enough for motorway speeds plus it sounded a bit, well dull. Adjusting the sound level in factory settings made no difference, I m guessing because the amp outputs where being bypassed (although balance, fader, equaliser worked) - this is probably why adjsuting the volumes in factory settings makes no difference on your set up. So I used another type of adapter that does what the factory headunit does and takes the speaker outputs and drops them to line out levels. This seems to sort the volume problem but only if I adjust the volume levels in factory settings. Ironically it sounds better aswell, I say ironically because in theory RCA line outs should give better quality than speaker outputs, especially if theyre being amplified and then being dropped down by another piece of equipment. I can only assume that it sounds better because the factory amp is designed to take speaker outputs dropped down to line level outputs.
[MTCB Android Head Units Q&A] kwalsh24:
Yep has a gain control, its next thing to Max, even has bass boost, its about half.

I believe your on the right tra k with the volage of the line outs, amd I believe thats the issue I suffer from, weak signal going to the amp which then it can hardly process till you're at a certain volume then the amp will actually do something...

So you took a feed off one of your speakers, which converted it to a low signal (high to low converter?)

I would so that, however I have a wagon, all my speakers are in the doors, and its slight hassle right now to rewire the RCA for a high to low converter, even tho I do have one laying in a box someplace lol
[MTCB Android Head Units Q&A] typos1:
I dont see the need for the re-wiring, surely the box has inputs for the speaker level outs and outputs for the line level outs, so you put it between the headunit and the RCAs that are currently plugged into the back of your headunit ? I spose you may have to buy some female RCAs to do it.

On another note, I was fully expecting problems with the built in mic, but its nowhere near as bad on my Klyde unit as I expected. Its a bit like using a smartphone in speaker mode - it does cut out a little, sometimes cutting the end of a sentence off, but it is usable, I had a conversation with a friend at 80mph and we heard each other fine, he was a bit low in volume but I sorted that by adjusting the BT level in factory settings, I also left messages on my landline voicemail and it was ok, far from the best quality but not bad at all. I ve not tried the external mic, partly because the cable is nowhere near long enough to go from the interior light, down the A-pillar behind the dash to the headunit, so I need an extension.

When driving I do get random volume toasts though, dont know why, am sure I set up Gala not to send toasts.
[MTCB Android Head Units Q&A] kwalsh24:
Hmm okay, I must be mistaken as to which box you're referring to, as the one I was mentioning takes a feed from the car speaker amplified wires (from the headunit) then converts them to a low signal used by the RCA feeds.

I shall pop onto eBay and see what's offered for a signal boost
[MTCB Android Head Units Q&A] typos1:
Yes, thats what I meant, something like this :

http://www.ebay.co.uk/itm/250743611517?_trksid=p2060778.m1438.l2649&ssPageName=STRK:MEBIDX:IT

Thats not the one I used, I got one specifically for my car with the Bose set up, but the one above offers adjustable gain. Are you in the US ? Cos Crutchfields also have a box that has several settings depending whether youre using a factory set up or not. Cant guarantee the quality will be any good doing it this way, like I say it might be that my Bose amp is specifically designed to amplify from a source that has taken speaker level outs and dropped them down, but its worth a try.

Heres the Crutchfield link:

http://www.crutchfield.com/p_142SLC4/Scosche-SLC4-Line-Output-Converter.html

But either way, theres no need for re-wiring, you put them between the speaker outs and the RCAs that you already have that go to your amp.

(And maybe youd need one that has 5 in/outputs for your sub as well.)
[MTCB Android Head Units Q&A] kwalsh24:
Hmm yeah the top link is what I was mentioning, the high to low converter... which I thought only worked when you took the feed directly from the amplified speaker out on the radio...

I did find this..

http://pages.ebay.com/link/?nav=item.view&id=280637557198&alt=web

Going to see if that will do what I'm after... looks as tho you feed the low in from the head unit into that box, and it will amplify the signal out of it.
[MTCB Android Head Units Q&A] agentdr8:
Check the Audio settings in PA and toggle DVC. Also, make sure the main volume knob in the Tone page is turned up a little.
[MTCB Android Head Units Q&A] typos1:
Yes, it does, that is what I am suggesting - you put it on the speaker outs from your headunit, it drops the signal down, then you connect the outputs from it to the RCA wires that currently go to your amp and are currently plugged into the back of your headunit. I didnt mean the RCA wires on the back of the headunit if thats what you thought I meant.
[MTCB Android Head Units Q&A] 1-2-Hak:
So I intercepted the powerOff function in the MTCManager to see how long the unit will stay on if its not told to go through shutdown.

The bad news is that it must be powered by a capacitor because it stays in standby for the same time without the acc power.

I did have the recovery mode with TWRP stay on without acc power so there might be something here that can be rewitten....maybe....but chances are low.

Might look at the brightness issue next.

Hi, I need some help to get into bootloader and get adb to work via usb.

1st thing is that I rooted with webdude's method, I used the newer version of the app, 2.1.1 (do not update to the very last one because is plenty of chinese tabs, and you have to choose one). Once rooted, I could connect to adb via wifiADB as 1-2-hack posted. And, I could do a backup with the cat /proc/mtd method.

Now, I want to connect to the unit via usb, so that I can flash from bootloader mode, but I cannot get the unit into bootloader mode.

I have done all you said. I power on holding the power button. I tried with 4 or 5 buttons, the others do nothing. When I power on holding the power button , the screen goes black, but when I plug the unit to the pc nothing happens, drivers are not installed (well, they already are because I installed them for wifiADB, but no new device is detected or whatsoever by windows). I checked on the device manager, and the usb port does not detect anything.

How can I put the unit into bootloader mode, so that I can flash or recover from soft bricks ?

thanks.
[MTCB Android Head Units Q&A] pakidermo5000:
I think the guy is just a seller for these "new" units. Otherwise, why to share skype user ?

[MTCB Android Head Units Q&A] 1-2-Hak:
Are you cutting off the battery power (yellow wire) and holding power while you turn on?

The usb cable must be connected to do this otherwise it goes into recovery.. well on mine it does.

Need to make sure u can get into this mode before you start modding otherwise you won't be able to recover.

If you flash TWRP you can get to adb via usb from there

You can download quick boots from app store to reboot to any of these modes but that won't help with soft brick.

What model you got?

Maybe by a couple of secs but not much :(
[MTCB Android Head Units Q&A] pakidermo5000:
What do you mean by the yellow cable ?

Do you mean unplugging it from any power source at all? What I did so far, is just turn off the car, and then while turning on keep the power button pressed.

To unplug the constant power source (I do not remember which color is it) I need to remove the glove box too, because I fixed the unit to the harness to avoid robbery.

However, if I understand what you said, if I flash TWRP, then I will be able to connect to adb from there and reflash the system in case I soft brick the unit, right?

My unit is the one with Audi A3 fascia, KGL-7683G. It has all the buttons (power, tune, menu, setup, gps, radio, dvd, ... etc)

I guess that if I do as explained in the wiki I will get into recovery, I will try.

thanks.
[MTCB Android Head Units Q&A] typos1:
I m sure I read recently in the AN21-U thread that the radio app on that DOES save station names, so maybe try one of the radio apks from the AN21-U ?

What about an additional external usb mic for Android ? Cant it then access the internet using the unit's 3G dongle ?

He isnt very clever if he is - the specs say its got a Telechips cpu, but he posted pics of a Samsung Exynos cpu !
[MTCB Android Head Units Q&A] 1-2-Hak:
Yes it is all power and that is frustrating - I was originally pulling the fuse and then putting it back in while holding the power button. In the end I put a switch on the yellow wire and put that in my glovebox so I could witch it on and off as I have been flashing it so many times.

Mine may be different as it only has a couple of buttons on the front. the power button also acts like a back button when the unit is running. The only other buttons I have are Mute, Play, Eject and Menu.
[MTCB Android Head Units Q&A] pakidermo5000:
Ok. Well, I could boot into recovery, but not into bootloader, using the reset method (isn't reset a way to fully stop the unit equivalent to what you do cutting off the yellow cable?, do you have a reset button 1-2-hak ? I had problems finding mine, it is a very small "button" next to the sd card. I had to push it with a tooth-stick. ) I think that the sequence to boot into bootloader and recovery is the same, proably having a usb plugged in makes the difference to boot into bootloader instead of recovery.

Anyway, I could not boot into bootloader mode, my computer does not detect anything.

Then, since I did not want to take apart my unit I used wifiADB to actually reboot the unit into bootloader (adb reboot-bootloader). THe unit rebooted, and I got a black screen, but my computer did not detect anything. Is it possible that the usb cable I am using is crap ? I took it from usb hub. Is it possible I have problems with the drivers ?

Offtopic: I read on the first pages of the thread that [MENTION=532077]blankers[/MENTION] managed to activate usb debugging from the " Factory Settings " tab (passw: 126). I tried with mine and there is no option for that.

Anyone
[MTCB Android Head Units Q&A] blankers:
No...I didn't do it from the factory settings.

This was at the time we were trying to get root, and I tried 'z4root' which didn't work, but when you run it it asks you if you want to activate USB debugging, which I did, and it takes you to the USB debugging settings where you can activate it. :)

Nope, thought that exactly, wouldn't require another line run, as i would just olug my rca cable feeding my sub into that box vs the line out of the radio, but would require more room for the box to sit in behind my dash, which I'm limited, so I just bit the bullet and bought that other item to see it it will do the job.
