[Android Head-Units] Mercury11:
Finally got around to installing my android 4.1 radio I had since around march. I will give this feedback to anyone interested. The radio I purchased was the two button one. The MCU and System was updated with the microsdxc pretty easy thanks to this awesome site. I bought this from amazon [SanDisk Ultra 64GB MicroSDXC Class 10/UHS-1 Memory Card Speed Up To 30MB/s With Adapter, Frustration-Free Packaging- SDSDQU-064G-AFFP-A ] and format to fat 32 from my desktop.

The vehicle I installed it in was a Jeep Wrangler 2014. The unit is much bigger than the opening of the dash molding so I had to sand it down a good bit. I bought the Metra 95-6511 Chrysler/Jeep DDIN 2007 Dash Kit which kind of looks like crap with it because its not as tall as the radio and it added more to the width but things could be worse.

After alot of cussing and a few fuses blowing because of my stupidity I finally got it up and running.

The steering wheel controls and reverse cam worked for me buying doing this.

I purchased a harness (Axxess XSVI-6522-NAV Non-Amplified Non-OnStar Harness to Retain Accessory Power) and (Metra Axxess ASWC-1 Universal Steering Wheel Control Interface).

The Non-OnStar harness plugged into the harness that was attached to my original factory radio. The ASWC1 connected to the Non-Onstar Harness. I used these color wires for me to get it all working.

This is the canbus connection:

Non-Onstar Harness PINK to Aswc1 PINK

Non_Onstar Harness BLUE/PINK to Aswc1 BLUE/PINK

The steering wheel controls took forever for me to figure out. The directions that came with the ASWC were wrong and the colors of the wires were off. I went to Axxess site for the direstions for my car and they worked nice. Finally I went into the System apt for steering wheel and had to select which buttons to use in order to activate the steering wheel buttons.

Android Radio (KEY2) WHITE/RED - to Aswc1 BLACK

Android Radio (KEY1) GREEN/YELLOW to Aswc1 BROWN

Cheap Reverse Cam from amazon:

Non-Onstar Harness GREEN/PURPLE to Android radio reverse wire.

Cam Red wire to brake light

Cam Black wire to ground wire.

hey guys, I can't posting outside links, but if you wanna grab the new firmware 2.7.9, go to google and type "Китаец прислал прошивку 2.7.9"
[Android Head-Units] KID52:
Do you know the source of these updates?

There are quite clearly different suppliers providing their own flavour, and I would quite like to be able to group the firmwares by supplier.

For example, the ones I have added personally are from Peter Chan.
[Android Head-Units] julsn:
can't say for sure about the source, but definitely the same source as for 2.7.4 firmware. I think it's from Quick Yuan.
[Android Head-Units] PsychoMcSatan:
There's a Russian distributor of these units so I'm guessing a Russian version of Peter Chan with direct Tonghai Create contacts is posting to that 4pda.ru site that seems to be getting the newest updates.
[Android Head-Units] KID52:
It's a fair enough assumption.

I'll see if I can go back through the system files I have and group them sensibly, that way it just makes it clearer what is an actual update, rather than relying on the system version which probably means nothing when comparing files from different sources.
[Android Head-Units] julsn:
btw, I have found a new MCU version for my device. in the 2.7.4 firmware MCU remained the same version as for .96
[Android Head-Units] johnnybags:
For what it's worth, this version works with the Ca-Fi DashLinq4 head units. Thanks a ton, I just installed it on mine!
[Android Head-Units] j2gifted:
Is there any way to get the laucher atyle on the dashlinq on to a regular an 21 u?
[Android Head-Units] PsychoMcSatan:
Just installed 2.7.9 and so far I don't see anything new. I was hoping for a new MCU, but they seem to be still on the 4.2.13 versions introduced with .93.

Still get the "Unauthorized UI" message so had to copy over the APK from .96 again.

EDIT: Just checked the Russian forum that has the link to 2.7.9 and I see a screenshot that shows a 4.2.15 MCU version. All I see is 4.2.13 in my /system/etc/mcu/ directory

http://solaris-club.net/forum/showpost.php?p=1204410&postcount=1385
[Android Head-Units] julsn:
PsychoMcSatan, scroll to the end of the directory and you'll see 4.2.15 versions.
[Android Head-Units] PsychoMcSatan:
Yeah, you're right. But only a a few models. I think I'll have to continue waiting before I'm able to have my knobs work in the right direction.

Preamp distortion

Anybody here have their head unit hooked up to an external amp via the preamp outputs? I'm pretty much unable to turn my unit up past "13" without getting distortion.

Im using just one pair of rca (rear speakers) to an 4 band eq that has 3 pairs out (frront L/R, rear L/R, subwoofer L/R) into a 4 channel (150 watt x 4) amp for the front door & rear door speakers (5.25" in the rear doors with HPF at about 300 Hz, 6.5" in the front doors with HPF at about 200 Hz) and two monoblock amps (a 300 watt driving two 6.5" subs on the rear deck with LPF at around 150 Hz and a 600 watt amp driving a 12" sub in the trunk with LPF at about 80 Hz) All speakers are 2 ohms and all amps are claimed to be "stable to 1 ohm"

I listen to metal, the brutal heavy kind & the distortion is nice at volumes between 10 & 13 (pleasant like a tube compression almost) but at 14 it's hard clipping. I have more than enough experience with gain staging (I've had a home recording studio for over 30 years) and 13 is just under half the full volume. I would expect to go at least as high as 70% max vol. All of my amps have a fair range of input sensitivity (Lo 125mV - 5V and Hi 250mV - 10V) but I have no specs on this AN-21U as far as its outputs are concerned.

How loud are some of you able to get yours to go & on what type of output system? Thanks.
[Android Head-Units] hjf288:
I was getting clipping/distortion with any android app i.e. Youtube, Built in player for USB sticks and Poweramp (Although poweramp could be adjusted to negate it)

I solved it by installing AlsaMixer(ROOT) lowering Main Playback Volume by 9 from 64 to 55.

Running alsactl store via sudo terminal and then adding alsactl restore /etc/asound.conf command to my init script.

Does anyone know if Viper4Android does anything on these head units?
[Android Head-Units] csabee69:
Hi Iscle,

What are your experiences with the unit you purchased? Is it really able to handle ELM327 Bluetooth out of the box? Did you managed rooting it?
[Android Head-Units] iscle:
Hi csabee69,

The radio performs very well, and I was able to root it with the .apk that you can download on the first page of the topic, and I don't know what you mean by ELM327 Bluetooth...
[Android Head-Units] csabee69:
ELM for OBDII diagnostics like Torque. As I saw in this thread the other devices cannot handle it but the seller states on the aliexpress link this unit can. But you didn't tried it I assume :)
[Android Head-Units] johnnybags:
The Ca-Fi is able to handle ELM327 bluetooth out of the box (and obdlink sx via USB for faster refresh rates, if you so desire.) It is rootable.
[Android Head-Units] mad212:
I installed it and messed around with the settings but noticed no difference.
[Android Head-Units] MFKinSINY:
Check the settings (driver status) while music is playing. "processing " will say either yes or no. mine said no for the longest time. Im not sure how i was finally able to get it to work with my unit but I uninstalled & reinstalled quite a few times and eventually got it to work. I went for subtle settings (slight eq, slight speaker boost, no fx) and i could definitely hear the difference.

---------- Post added at 11:02 AM ---------- Previous post was at 10:58 AM ----------

yes it does (on mine anyway) i had to uninstall/reinstall quite a few times to get it to work. I honestly dont know "how" I was finally able to get it to work, but you need to check the setting (driver status) and its should say yes or no next to "processing"
[Android Head-Units] booba5185:
I wonder if installing the apk as a system app would help it work right away?
[Android Head-Units] MFKinSINY:
quite possibly. I wish I could say for sure whether I did or not. I didn't need to edit my build.prop as the entries werent even there
[Android Head-Units] booba5185:
Just tried and no dice, no processing. Just to be clear, when you install the driver (the first time you open the app), what do you select as the your CPU? When you uninstalled\reinstalled, did you uninstall the driver before uninstalling the app?

---------- Post added at 09:02 AM ---------- Previous post was at 08:54 AM ----------

Self quoting, but I got it. In Poweramp, you need to make sure that Direct Volume Control is DISABLED. It's in Settings->Audio->Tweaks

No touch or button resposne from unti. boots up fine but no response. What firmware can i use to reset it? Ca-Fi 4.1 Dashlink4
[Android Head-Units] TeamHackura:
Fixed via restore with files sent from support
[Android Head-Units] j2gifted:
Got my replacement unit and installed it today. Idk why but it seems a bit snappier, and some apps from the play store that didnt function properly on the returned one work fine on this one. Also the menus are a tad different. Idk why tho...

QUESTION:

HOW do I get the radio to save to my new sd card in the front slot by default instead of the built in memory? I want to use that for app files, offline maps, offline music for spotify... but it saves internally and fills up rather quickly.

Radio stations does not light

Dear colleagues!

I have a problem that you cannot solve.

Did not get to highlight the selected radio frequency in the radio.

Firmware the factory was 2.6.70, then put 2.6.77, and then 2.7.4 and not on the same firmware selected frequency radio does not light.

Change the MCU on different models does not help.

Sleep mode works.

Need help, thanks!

[Android Head-Units] balaes:
???

What is this upgrade ?
[Android Head-Units] TeamHackura:
Only for Ca-Fi
[Android Head-Units] Miwer:
I don't mean to be disrespectful here, but I think you need to make your own thread for Ca-Fi systems, and not pollute this thread with updates that are not for the AN-21U systems.

Thank you. ;)
[Android Head-Units] TeamHackura:
I think your are right. I saw done previous Ca-Fi stuff posted and thought I could help. I'll show myself the door
[Android Head-Units] johnnybags:
This is the same hardware as the an21u, i believe. At least a few pages back when i posted the info screens people here seemed to think so....:confused:
[Android Head-Units] Miwer:
Yeah... The hardware may well be the same (or closely similar), but the firmware and software is clearly not the same (looking at the pictures, and the update files), and that makes it a completely different device (i.e. not compatible with the AN-21U, which this thread is about).

I suspect you cannot update an unbranded AN21 unit with the ca-fi software, nor vice versa.
[Android Head-Units] johnnybags:
maybe so, but then again, the patched rootmyan21-u worked on this unit, so there must be SOME software similarities, no?
[Android Head-Units] IRatchett:
So I just got this unit and installed it. Now I want to update it. Mine is 2.6.70 ,can I just update to 2.7.9 or do I need to slowly update to it? Also anyone using the WiFi dongle that came with theirs? Mine seems to suck lol. I was thinking about getting a better one. Any thoughts?
[Android Head-Units] Miwer:
I'm sure there are SOME similarities in the software - it is based on the same android version after all. But the Ca-Fi is still a different system than what is discussed here, so can we please stick to the topic, and not mix up the different systems?
[Android Head-Units] IRatchett:
Also how do I know which radio I have?
[Android Head-Units] PsychoMcSatan:
If you're running 2.6.70, then you have the AN-21 U discussed here. There are slight variations in face-plates and those differences are handled by the MCU images. These don't get updated unless you apply a new MCU manually.

As far as the WiFi dongles, check the Wiki at http://xdaforums.com/wiki/Tonghai_Create_AN-21_U

It has a section which discusses dongle options.
[Android Head-Units] IRatchett:
ok awesome glad im in the right place lol. I have the one thats in the OP. But about updating to 2.7.9, can i update right to it. Im gonna root it first and make a backup of that MCU just in case something happens
[Android Head-Units] julsn:
TeamHackura, don't listen that guy. take it easy. you're doing everything right, trying to help. I want to personally thank you TeamHackura and johnnybags, both of you made my day when gave these links to Ca-Fi firmware. I've an old version of the firmware from a chinese link, but in the new firmware I found something of note. I hope it solving my puzzle and I'll give some thoughts for additional functionality of the AN-21 U
[Android Head-Units] NickNoltePop:
Update!

Well, i updated from 2.6.60 to 2.7.9.... Nearly everything worked fine... nearly...

Bluetooth works now, after it doesnt work on 2.6.96.

only the knobs dont work.

any ideas?

thanks a lot
[Android Head-Units] PsychoMcSatan:
There's no process for backing up MCU, but updating the system software won't update MCU. Check what version of MCU and see if there's a new matching one under /system/etc/mcu/ after you've updated and rooted. And it seems that versions can be jumped so I think you're okay going straight to 2.7.9.

Those components generally are managed by the MCU. Perhaps what I said up there about MCU not being touched by system update is not true? Do you know what version MCU you have, before and after upgrade?

Are you sure you didn't go to "Choose Model" as that will update your MCU to what it thinks you need, but it doesn't work for all radios (not for mine at least). What does your radio look like. If it has two knobs, what side is the volume knob on?
[Android Head-Units] NickNoltePop:
before i had 4.2.13-9-10-4502 and now i have 4.2.15-5-20-8001

System is 2.7.9

2 knobs. left is tune up/down and right is volume.

I tried with "chosse Model"... the knobs will work then, but Bluetooth wont work!
[Android Head-Units] Kn0ck0ff:
So effectively , download new firmware , put onto formated sd card & run system update from general settings ? does the file need unraring ?
[Android Head-Units] TeamHackura:
Thanks. I'm cool as a cucumber. He is right though. We should be posting in XDA Ca-Fi thread. I'm mostly posting in ft86club Ca-Fi thread.
[Android Head-Units] IRatchett:
Thanks I'm now rooted and updated to 2.7.9!!
[Android Head-Units] johnnybags:
Thanks, I figured there was something to be gained from it, that's why i posted it here. Glad to hear that i might have been right.

Yep saw people wanting Ca-Fi info and lurking here so u posted links to downloads. Was going to out prior read link but ran out of time. My personal apology it's this thread here. I'm dc2r on that forum

I have the android car radio but I do not have a menu button on my radio. I am stuck at the boot screen and f***ed. I cant get it to boot to update the firmware or software..! Please Help.
[Android Head-Units] Cebulon48:
To whom it may concern :D

Updated my T7019a HU with latest System-Files 2.7.9.

No problems encountered.

Does anybody note any changes/improvements ??

Do the "SYS" - Apps change in any way, when updating system, or are these covered by different files (talking about Radio/Ipod / Bluetooth phone ...) ??

Thanks for posting the updates

[Android Head-Units] sciallo:
What face do you have? (two knobs, one knob, no knobs, vol on the right...). I believe any face button + power should trigger update... Try them all
[Android Head-Units] IRatchett:
After I updated my radio to 2.7.9 it's now telling me I need to update the binarys for the root. It has install in recovery or just install. If I choose just install it doesn't work. Should I choose install in recovery?
[Android Head-Units] ngy:
sigh. started to have issues with my poweramp sound. it was playing fine (just on acc) until i started my car. when the car was cranking, the unit shut off (naturally), but when the unit rebooted, I got no sound from poweramp. I read some solutions on the thread, but none worked. I hard reset once already, and I dont want to keep hard resetting to fix this issue. anyone have any idea how the sound is routed?
[Android Head-Units] Kn0ck0ff:
i too have noticed this , maybe a fresh root is required , not to sure . Did you also notice google play had gone & my bloody browser wont open , had to download firefox apk on pc & transfer to sd .

How can you view system files & apk , es file explorer doesnt let you go to deep into the files system , i wont let this live wallpaper beat me , i will get it to save lol , only been trying to do it for a week lol , firmware upgraded yet still no joy , i need audio glow in my life haha
[Android Head-Units] IRatchett:
No my google play is still there, and chrome still works. Im on the fence with this radio. The screen doesn't look that good when your above the screen looking down at it on apps like google play and google maps. The white is bright but the text seems to fade away. But if you put your head down even with the screen then it looks better. Are all the screens like this. Can you guys test out your radios? Mine is in my expedition and the doesnt sit at an angle like some cars.
[Android Head-Units] PsychoMcSatan:
Yeah, I'll add this to the WiKi as it seems to be fairly common issue when battery voltage drops below probably 10V or so. My working theory is that the MCU gets out of sync with the Android sound. Pressing the reset button (little hole that looks like the microphone so be careful) does seem to clear this up, as does disconnecting the battery.

Yes. Rooting needs to be reapplied after updating system files.
[Android Head-Units] ngy:
thats for that, i'l give that a shot, otherwise this unit works exactly how i want it =) now if only we can get a home screen that looks more like a home screen in a car... haha
[Android Head-Units] PsychoMcSatan:
If it was working when you had 4.2.13-9-10-4502 then reapply that one. Or was that the one where your knobs didn't work?

My model sounds physically identical to yours, and the closest to fully working MCU is 4.2.9-7-10-2501. That's the only one that Bluetooth works and knobs work, but backwards.

Also, be aware that Bluetooth generally takes two reboots to stabilize. With a few MCUs, on first reboot I'll have bluetooth working with the same name and password, but then on next reboot, the name and password in settings will have changed. Curiously, my phone still sees the radio's old bluetooth settings and will sometimes even connect, but Android does not see the connection.
[Android Head-Units] NickNoltePop:
4.2.13-9-10-4502 was the full working MCU.

But i can arange that the knobs aren´t working... i´ll wait for the update from 4.2.15

Now bluetooth works 100% so im happy at all. the steeringewheel control also works, so the knobs are not as much important as bluetooth.

Next step is changing the Radio.app.. i´ll change the app cause now i cant set ON/OFF the "TA".

unfortunately i orderred the unit with DVB-C... and not DVB-T... maybe i can change that?... i dont know! does anyone have some ideas?
[Android Head-Units] ngy:
thanks a bunch, this fixed my problem!
[Android Head-Units] sciallo:
Not sure it's the same problem you're describing, but I brought this up a while ago and never got to a definite answer.... It looks to me like some fonts are missing and default to a faded and thin font that is barely readable, especially in playstore, browser and some other apps. the only solution that was brought up has been to make things bigger by using xposed module "app settings". While that is a very useful module, making every app with washed fonts look huge is not my ideal solution to that one...

I partially fixed it by installing a different font through rom toolbox pro font installer. It was a quick fix for now, it fixes some of it but not all, later on I will try copying all the fonts the unit calls for in there. (and by later on I mean some day :) )

What year expedition? I am installing mine in a 98. Would you mind sharing what you used (or come up with) for a face trim?
[Android Head-Units] IRatchett:
Thanks ill looking in to changing the fonts, the radio is still worth it no matter what for the price it is you know. I have a 04 Expedition. I first bought the Metra 95-5026 Double DIN but didn't like it at all. The trim was to thick and the volume button rubbed really bad and didn't come out past the trim. So I found another kit which is the Scosche FD1428B. I had to trim a very little bit for the volume button but the kit worked great. There is a small gap all the way around the radio but it looks fine.Its how the OEM looked also. I call this the air flow edges lol.
[Android Head-Units] sciallo:
Ah, thanks, but 98 is completely different I think...
[Android Head-Units] IRatchett:
yes it is but just look for one that trim isnt very thick.
[Android Head-Units] KID52:
I think I mentioned this issue with the screen in my review, certainly I have mentioned it in the jungle that is this thread.

It's because it is a cheap TN panel, so viewing angles are awful. I found in my car it's not so bad as the unit sits at an angle.

It's the same as the old (and maybe new) TN panel monitors, if you look from above the screen is washed out, if you look from below everything is dark, if you look from the sides it has little effect. Would love to have a unit with an IPS or equivalent panel, but have not seen one yet. No idea what kind of cost increase that would bring though. I suspect the panels we have are worth a couple quid if that.
[Android Head-Units] IRatchett:
Yes its not bad on the Radio app because its dark i think but anything white and its washed out bad. Still its a great radio so far I'm just waiting on my WiFi dongle from amazon because the one they sent me is junk. I bought 2 to try out. I'll post how or if they work when i get them tomorrow

Hi guys, for all of you that want to use the external SD instead of the internal or have problems related to apps that don't see external sd

I suggest to use this app "DirectoryBind_0.2.0o.apk" that you could found here http://xdaforums.com/galaxy-s2/themes-apps/tool-directorybind-data-to-externalsd-t1410262

It works perfectly.

You need root, and please keep in mind that SOURCE folder is the folder path where you want to keep files (for ex External SD)

and TARGET folder is the folder path to be expected from other apps (for ex Internal Inand or Sdcard).

Please read instructions!
