what are the steps for that?

Thank you, lots more to go :)

Remove Stock App

Hi,

Can anyone tell me how to remove the stock Apps. I have rooted the system but do not find the apk file in any of the folders in the root directory.

I just want to remove Music, Video, Equalizer app.

Regards,

Are you able to use Poweramp without any problem? When you play music on poweramp does the stock Music player starts automatically? or vice versa?
[Android Head-Units] booba5185:
Yes, no problem, you just need to open the radio app and hit the back button (not every time, just the first time). That should be in the first post.
[Android Head-Units] bencyp:
Does not work for me. If I uninstall the Music player(stock) then no 3rd party player will play the audio. I do not get any sound. I am able to get sound from Radio, Video player (Stock) and iGo Nav.

To get the sound back, I have to install the Stock music player and open it. if i do that then both the stock player and the poweramp play the audio at the same time. if i stop the stock player and exit it, sound stops.

Very strange behavior. i have done factory reset and also reset using the button. Still no luck.
[Android Head-Units] booba5185:
Why are you uninstalling the stock music player? Leave it installed, open radio, hold the back button on the screen (not the hard button), then go open Poweramp. If this doesn't work, then hit the reset button with a paperclip, depending on your model it's normally in the upper left of the unit.
[Android Head-Units] bencyp:
Hey, Were you able to solve this problem? I am also having the same problem and I have tried different Players without success. Please help

T-Mobile Jet 2.0 Laptop Stick

I have used the T-Mobile Jet 2.0 Laptop Stick with PPP Widget by Josua Dietze configured with epc.tmobile.com as the Access Point Name, no username or password, left the dialing string to default (*99***1#) check and set PIN has been disabled, no HTTP Proxy, Use Wifi to show PPP Connectgion status is enabled as well as disable usb sleep, auto-start and auto reconnect. I use auto device detectionand all three options under troublshooting are selected in my case.

I will be getting another 4G dongle soon to test and will let you know how that goes. :)
[Android Head-Units] Suzook1:
4g capability would be very nice. Keep us posted
[Android Head-Units] juncey:
I was pulling down 3-10Mbps and up was almost always 2Mbps. So I'm not sure if it's due to the area recently being upgraded to support T-Mobile or if something was interfering with my dongle. I tested it using my hotspot and was almost always getting 10 meg down which leads me to believe it's the network. I'd like to check out AT&T but they don't offer unlimited Spotify or Pandora streaming :P I should have a different T-Mobile (Rocket 4G) dongle on Thursday or Friday so I'll let ya know. :)

*Edit* I just ordered two other USB dongles. The LG AD600 (AT&T Adrenaline) and Novatel 551L (Verizon). Both are reported to be LTE capable but I won't know if they'll even work until they get here.

I also wanted to note that I intentionally ordered older model dongles because I figured they're the most likely to work. As I test them I'll post my results. :)
[Android Head-Units] bencyp:
hey Boob,

I was able to do this and the 3rd party player works as desired. However, after restart its the same problem. I have to open radio and do the same thing as you have mentioned. I shutdown the system when the player is playing. When booting up, player does not open automatically so thats the problem

Also, my Poweramp does not see USB drive. It only plays audio from iNand drive. n7 player sees the USB drive but somehow I don't like that player .

I'm wondering if anyone else is having Torque Pro gauges freezing issue. I'm using it with an OBDLink SX on a 2006 Suzuki Grand Vitara. Torque Pro starts up no problem. Whether its the gauge on the home screen or the guages on the dashboard, at the beginning everything works fine. It really depends, but sometimes it can be from 1 minute and other times it can be up to 5 minutes, Torque Pro refreshes (you can actually see the refresh as the screen flashes) and the gauges freeze up. At some point they unfreeze and start back up again but this is the behavior I am getting.

Weird thing is that

- I am not getting any adapter errors on the OBDLink SX and my previous Chinese clone adapter.

- This was happening with the Chinese clone adapter, so that is why I decided to get the OBDLink SX but same thing here as well.

- I have "Fast Connection" checked in the adapter settings, but still getting this issue.

- I have searched through the Torque Pro forum and the admin there swears that pausing and freezing is not being caused by the app but by the hardware (i.e a bad OBDII adapter or the sensors themselves). I am currently using a name brand OBDII adapter, but same issue is happening like with the Chinese clone adapter.

So my main 2 questions are:

1. Has anyone been getting the same issue and how did they fix it?

2. Is there any way to stop Torque Pro from loading by default? It detects that a USB device is connected and the app loads every single time I start the car. I've tried forbidding the app to load by default through Task Manager apps, but it's the connected USB OBDII adapter that is causing the app to load every time.
[Android Head-Units] Skratchuk:
Haha I have that as well I thought my kids had put it on there I'm guessing if your rooted you should be able to delete em.
[Android Head-Units] gwinn:
UI is unauthorised, please contact supplier

:confused:

Just upgraded to the latest system version from this topic on my head unit. I am now getting a message saying that the UI is unauthorised. Any ideas how I get rid of this message? It doesn't appear to be reducing functionality but it is a little annoying as it sits on top of all of the apps etc

Cheers

[Android Head-Units] gwinn:
Thanks, my bad! :o Completely missed that post for some reason. I'm usually very thorough at searching and scrolling up lol

Has anyone found a way to get Bluetooth devices other than phone/OBDII to work on these head units? I was hoping for a Bluetooth keyboard but can't seem to unlock full Bluetooth features. I noticed that from most of the posts about it that it could be a hardware restriction???

Also, I have a 3G dongle attached and the sim has outstanding voicemails. When I try and check them I get them the head unit appears to dial but no audio etc...... Is there a way to use the 3G dongle/sim for calls and texts or does the device only see this as a data device? I haven't found the default android messaging app or dialer as yet

Cheers guys

Hi all

Another little issue, don't know if anyone can help??

I use 3CX MDM for remote management of Android/IOS/Windows devices. Normally works fine on all Android devices I've tested on. However, installed on my head unit and it fails to connect to their server. just get a retry message and it stays disconnected.

Tried doing a service scan on the server and it can find and query the available services but the software just won't connect. This has been tried over wifi and 3G to no avail.

Has anyone else had any experience with this app and had any luck getting it to connect?

Cheers

PS server it is trying to connect to is server.mobiledevicemanager.com

Hey all. I asked before but got no reply. I want to rip dvd or blu rays to my micro sd for playback. Can anyone give me the best steps to do so (software etc)

Many thanks
[Android Head-Units] Skratchuk:
On pc or Mac if it's mac I would suggest free dvd ripper

I use to use nero express many moons ago.
[Android Head-Units] Suzook1:
So just rip the dvd and copy to the flash. Any preferred file format. This is a WIN pc

thank you
[Android Head-Units] Suzook1:
oh almost forgot, triple screen action......

the 7 inch android build continues ...........
[Android Head-Units] juncey:
Format depends on the preferred video player app.
[Android Head-Units] Suzook1:
can you suggest one

What app do you use to play videos on the head unit? clone dvd mobile is one I found to rip
[Android Head-Units] juncey:
I don't use any video players in my car (I would kill myself from not paying attention) but the one I use for my phone and tablet is MX Player. Not sure if that would work on this HU but worth a shot.
[Android Head-Units] juncey:
Not sure if anyone has posted this but I recently sent an email to support about which model dongles work.

[Android Head-Units] heaky:
Thx for your reply, copied the file and the message disappeared. Unit was working perfect before, but after this modded apk, the steering wheel is not responding and cannot switch to radio by using the touchscreen. Are you sure this apk is the same for this firmware version?
[Android Head-Units] patrickoneal:
Anyone know how to do a factory reset? I rooted, then starting messing about, and I'm stuck on the boot animation :(
[Android Head-Units] KID52:
Mine has the same speed apparently, just noticed that.

Also, there is a screenshot option in the menu.
[Android Head-Units] KID52:
No idea... There is a reset button top left, press it with a pin, or hold it, see if that works?

Unlike the other unit, you cannot update from boot, it has to be initiated from the settings menu...

If you find a solution please let us know, as I'm sure it will come in handy!
[Android Head-Units] patrickoneal:
I got it to start again.

How I got stuck: I used the root app a second time to enable wireless adb to see if I could do an adb reboot recovery, which just caused a reboot. I then deleted the file the local.build file again, and rebooted, and ended up stuck.

I found that if I put the latest update file you supplied on an SD card, then powered up by holding the volume knob down, and holding the home, back, or menu button, it would start the update process from the SD card without having to start the OS. It's now started, and my apps and such are still there, and it's in slow motion with the black icons. I should have it back running correctly in a few minutes.
[Android Head-Units] KID52:
Ah, that is very useful to know. I will definitely add that to the first post in case other people have the same problem!
[Android Head-Units] patrickoneal:
I think I figured out what I did... I deleted /system/build.prop instead of the correct file. This makes the stereo angry. Good to know that we can recover from stupid mistakes.

---------- Post added at 08:25 PM ---------- Previous post was at 08:20 PM ----------

Everything is back to normal again.

I did notice that my MCU version is older than some others here. It did not update when I updated from the SD card.

Also, in regard to my earlier question, have you notice that black text in the play store and other apps is very grainy and hard to read?

Thanks.
[Android Head-Units] KID52:
Hmm sorry about that, was going to reply and then completely forgot!

Yes I have, it looks shocking, Play Store and Google Maps are the worst ones. It looks as if the contrast is screwed up.

I assume you are looking at it from above yes? Basically I think it is because the screen is just a cheap TN panel. If you move your head so you are looking up to the unit, you will find it looks a lot better (whereas now the same thing happens if you look at a dark app with light text). I am lucky in my car that the screen sits at an angle.

Another thing to check, if you open up the grey settings menu, and look at the screen closely. Do you see a sort of horizontal flickering? I have it and find it extremely annoying.
[Android Head-Units] donaldta:
Yeah, that will frustrate *any* Android device. Since that's the file that determines how and what it loads.
[Android Head-Units] patrickoneal:
I wonder if changing the DPI to make things a bit larger would make things look better. I imagine doing so would screw up the factory applications though.

I don't see any flickering, but that may change when it's actually running in the car. I see a bit of banding in the gradient. It may be flickering, and I'm just not sensitive to it.
[Android Head-Units] KID52:
Hmm, it's not banding.

The best way I can describe it is if you take a video in a darker room, you will see noise on the video, I see this, hence my description of flickering, in horizontal lines.

I tried to take a video of it but it's hard to capture, but very obvious if you look closely, and even from 50cm away I can see it.
[Android Head-Units] donaldta:
Are you sure about that? In the picture that you attached, the "Power Cable" wires has #1 CAN RX (Yellow) and #2 CAN TX (Blue) which seems to elude that it can connect to CAN BUS.
[Android Head-Units] KID52:
I am not 100% no, I am just basing it off what was mentioned previously by another member in this thread.

I cannot test it either.

It is definitely possible that you don't need any extra hardware, but someone else with CANBUS will need to test it.

Edit: here is the quote.
[Android Head-Units] donaldta:
I think the problem is that there's a general assumption that all the units that are advertised with similar specs to AN21-U are actual AN21-U units with a different faceplate. I'm not so sure if that's the case. I think there's a degree of difference that can be associated design from the different sources. For example, the external Can Bus module which chris.r.r pointed out of the VW specific unit could be due to the limitation of space or shape that is allowed when swapping out with the factory head unit.

When I decompiled the the com.tw.service_a5a4.apk, it did not look like any of the code was obfusticated. I've attached a copy for you to take a look.
[Android Head-Units] patrickoneal:
I installed the xposed framework, and this module: http://repo.xposed.info/module/de.robv.android.xposed.mods.appsettings

I set the playstore DPI to 300(I think these are percentages, not sure), then set it to force full screen to hide the top bar. This makes everything pretty large and reasonable clear. I honestly think having everything huge is better regardless of screen quality, being that it's not in your face like a phone. I tried various settings and this seems to work best for now. I'll read up more on the module, as there is a ton of functionality. I also made waze run a bit larger, and at full screen. It's a hassle, but I think you'll find it makes everything quite a bit more usable.

Maybe in another year or two the Chinese will offer one with a nicer screen, or shame Kenwood, Sony, Pioneer and the like into making a real Android head unit. I suspect the reason no mainstream units like this exist is because you'd never have to upgrade to a new unit for incremental functionality updates.
[Android Head-Units] djblaze852002:
Got my unit!!

So I got my unit in today and installed it. I have only had a few minutes to play with it but I want to discuss some immediate observations... I have been unsuccessful in getting Google Now or any google voice actions to work as they require the newest version of the Google Play Services. The store doesnt seem to want to update the installed version past a 3.XX version when 4.XX is the current version out. I have downloaded a 4.XX apk and will try to install it manually tomorrow, hopefully it doesnt screw anything up.

When playing google music, there is a little bit of a wait between changing tracks and the unit turns on whatever default app was open last, so its good practice to open the aux app first so that something like the radio doesnt turn on between ever change in song track (annoying).

The bluetooth phone App seems to be a POS... It really doesn't work well other than being a bluetooth receiver. i wasnt able to get it to access my phone's contacts, or easily place calls, Its still easier to use the phone handset to initiate a call, then tell it to use the head unit for the audio and continue the call there...

Lastly I installed this head unit using the Scosche double din kit for my car (2011 rav4). The trim piece that is supposed to go around the faceplate of the unit is too small.. I ended up not being able to use it, leaving a small 3mm gap around the edge of the faceplate. (perhaps this unit is just slightly larger than standard double din head units??)

Ill play around more tomorrow and hope to get a more detailed review of what can and cannot be done with this unit.
[Android Head-Units] patrickoneal:
I've just been messing with mine on my dining room table, and after I read your post I grabbed an extra American International double din kit I had for my 350z. I can confirm that this unit is slightly oversized. It looks like if it was mounted far enough back, the kit wouldn't cover any of the buttons or ports, but I think it would look like crap. I think I'm going to install it in my F150, I've got an old Kenwood double din in there now, and I'll report back in a few days on whether or not it fits. Some careful work with a file and some matte black spray paint would be the best way to enlarge the kit bezel a hair so it fits.
[Android Head-Units] omarko:
which one is it ? can you provide a link ?
[Android Head-Units] djblaze852002:
http://www.ebay.com/itm/Android-4-1..._Dash_Units_w_GPS&hash=item19e601fc9f&vxp=mtr

This is the unit I got. It was about $300. It seems the be the same unit everyone here is talking about. I am going to try rooting tomorrow...
[Android Head-Units] KID52:
Mine automatically updated without issue, just open in, sign in, close it, wait a few mins, open again, should be newest version. No need to download an APK.

It turns on the most recent default app between song changes on Google Music? That is odd.

Mine decided to copy every contact on my list three times. I had no issue making calls apart from the microphone being very quiet.

Yes, I think I mentioned this is my review video. There are typically two double din "standards" and this is the larger of the two, meaning it doesn't fit most European adapters. I just filed a few mm off each side, and you would never know it has been done if you take your time.

Will be interesting to know what sort of things you do. I think I'm sorted with mine as long as I can get steering wheel controls to work with non-stock apps.
[Android Head-Units] patrickoneal:
Any tips on disassembly? I've got an external mic I want to add. I popped the top off, but I wasn't sure if the next step was to remove the DVD drive or what.

My plan is to run a piece of 2 conductor shielded cable from the mic pads at the front of the unit to a 3.5mm jack I'll mount on the back.

Torque Pro gauges pause/freeze randomly

For those using Torque Pro, is anyone here having wired and random pausing/freezing of gauges with this car stereo? The app refreshes and then the gauges freeze up. I'm thinking it might be a MCU issue, because I am having this issue for both the clone Chinese USB adapters and for the OBDLink SX USB adapter.

For those who are not experiencing gauges freezing up on you, can you please tell me which MCU version you're using with Torque Pro? Thanks in advance, because I'm desperately trying to find a solution for this.

You have the same last 4 on the MCU as I do and I've been testing all of the available roms/firmware, even the "4.2" ones with success. Just make sure the firmware you download matches the 2101 MCU and you SHOULD be safe but that's your call. I'm still not going to say go for it with 100% but now you have a good place to start looking for upgrades. :)

---------- Post added at 04:11 AM ---------- Previous post was at 04:08 AM ----------

When you flash an update properly you'll see green words. UPGRADE START then two or three random strings and then UPGRADE END. Don't worry about how long it takes to reboot unless you've been waiting for 5 or more minutes. You'll know it "took" when you see Android Updating xx of xx before being taken to the home screen.

---------- Post added at 04:20 AM ---------- Previous post was at 04:11 AM ----------

Actually, you should be fine to use the firmware listed on the first page. :) if you look at the Previous Versions you'll notice System version 2.7.4 which matches. :)
