Flashed 2.8.8, updated the mcu which is included and reset to factory defaults...

Result not working bluetooth..

Anybody a suggestion for a (older) version to get the bluetooth working again?

Thx!
[Android Head-Units] roystervi:
I just got mines working ... tell me what are happening to the bluetooth l was having the same problem but solve mines. do your cell still connect to the car BT but you still don't have hands free?

and when you launch the BT app is the BT app empty ?

I notice when I go back to 2..7.29 my BT will work fine but when I upgrade to any other version my BT stop working

also try going back to your original MCU then upgrade to 2.7.29

this is what fix my BT

with the help of shadowmike my BT is working again. if you give more info I can help more

also go back to port #569 and you will see that I had the same problem like you and what it took to fix it.

Newsmy Carpad NU3001
[Android Head-Units] jpapadami:
I think he's talking about the Newsmy NU3001 referred to from post 5675

The specs are better on the Newsmy, but you also have to have a separate Android box somewhere in the glove. I personally think that the AN21-U specs more than enough fulfills my needs even if though the full potential can't be met. Keep all of this in mind when you choose. If you do end up going with the NU3001, here is a link to a cheaper price as most are selling for $678 + shipping. In the NU3001 XDA thread, they're also talking discount days starting on 11-11 on Aliexpress. Just be careful when purchasing from Aliexpress as there are many bad sellers out there.
[Android Head-Units] gklute:
thanks for the link thats a good price for that one...

whats the best price for the "AN-21 U" theres so many posts its a bit overwhelming..

with the AN-21 does it come with the ISO cable or do i have to solder... if it don't is there a per made cable i can buy???

Boot Loop

Hello Guys,

I have this Android 4.1.1 VW Car DVD GPS Navifor VOLKSWAGEN

aliexpress.com/snapshot/6072993258.html

But now it doesn't start up anymore, its stuck in the boot loop.

I currently have the following files:

-KGL(140514) with update.img and mcu.img

-Android 4.1-2.7.29 with 8e3513e2-ea4a-11e2-8a0f-000c29ba27c0 AND 8d8d1b1a-ea4a-11e2-a661-000c29ba27c0

how can I fix this?

I suppose I can just fix it by the new firmware?

What are the Key combinations for installing the firmware/MCU (like Power button+Reset button,...)

Thanks!

~Michael
[Android Head-Units] jpapadami:
I really can't say what the best price is. You'll just have to search on Aliexpress or eBay for units that have the same specs as the AN21-U with the same UI. As for the ISO cable, my unit was just wires, but you can always buy a separate female ISO harness, color code the wires, and connect them. No need to solder them, I used male/female connectors.

---------- Post added at 10:49 PM ---------- Previous post was at 10:45 PM ----------

I believe a whiles back in this thread it was mentioned that 2.6.60 firmware was used for bootloop issues. Search through the thread. Key combinations to start the update process should be Home + Power. After that, you can update to whatever firmware you want.
[Android Head-Units] cool_head:
Hey, forget these update.img and mcu.img. those are for hui-fei units!

Just put the 8e3513e2-ea4a-11e2-8a0f-000c29ba27c0 and 8d8d1b1a-ea4a-11e2-a661-000c29ba27c0 files in the root of a sdcard and press reset+power. The "UPDATE START" will appear.

My universal an21 was $260+ shipping, free backup cam, I also purchased a 3g dongle for 20 extra. 3g dongle is also a card reader so it's a 2in1

I don't trust aliexpress, I use eBay and only one seller. But they usually only have the universal

Hey guys, i'm really new to this.

i read the op and wiki and a few posts.

yet i have a few questions.

what is the latest version? (can u give me a link?)

-- in wiki page, there is 2.8.6, but its only 17mb and after installing, nothing happenes!

i have the "ui unauthorized ..." i know the work around, but i also found that there are flash-able firmwares, that fix this automatically.

the repository is outdated i think and i can not figure out what is what in it!!!!

can u help me?

and the last but not least!

my mcu version is : 4.1.0-7-10-2501

i was wondering if i should update it too! and what does it do if i update it? can u give me a link if i should update it too?

what if i want to clear everything already on it? (remove data! fresh new, like just out of the box? i installed a baidu root (old version) and i cant find and remove files it copied to my device!!!! not even with factory reset!!!!)

any ideas about having google apps? play store? maps and ets?

(i read a few about mcu on the wiki page's external link. but i didn't find out what it is and what does it do, or what happens if you update it. ps. not updating it as u said!)

but can you tell me what it is and why shouldn't i update it?

i know im asking a lot and i'm realllllly sorry, but this thread and u, are the only things i have, that i can ask for help.
[Android Head-Units] shadowmike:
The mcu is what makes the hardware work... As long as it's working I don't update it.

This radio already has Google play store. Just add your account.

There's no real point in a factory reset except for the unnecessary task of 're installing any apps.

Your unit should also have a map application, search for an igo folder using a file explorer and install the apk in it.

If you will have good internet , Google maps worked fine for me. But I enjoy a dedicated map when there's no internet

how can i install google maps!!!! (in my phones and tablets, it was a gapps.zip package which we should install in recovery!!! but nothing here! no recovery, no gapps, nothing!)

sorry, maybe my internet provider is having problems! (can you upload it there? it's really frustrating! 27% now!)

the head unit is for SsangYong Actyon.

it was installed already when i bought the car.

i wanted to change it, but after using it a bit, i started to like it.

but i couldn't find anything about it anywhere.

so i searched in alibaba.com and found the supplier! i emailed them and i asked them for help. but they didn't!

so as always, i started searching in xda, and i found this awesome thread.

i started reading it, the hardware is the same, and as i looked in to old pics, the ui is the same too.

so here i am, messing with m car dash audio system! bye bye WinCE!!!!

did you connect any amplifiers to it? or headrest LCD? or front cam? any modifications?

any apps modified? (i saw you posted a few pics, and u were trying to change the reverse cam lines, any lock?)

some thing weird happened last night!!

my SDcard is not working any more.

its 4GB, but pc says 28gb un-formatted. i couldn't format it either with PC or phone.

it has never happened before to me. after updating to 2.7.29, i removed my sd from head unit, went upstairs, downloaded 2.8.8, tried to copy it on my SD, and "BAM"... not working anymore.

did the head unit destroy my SD?
[Android Head-Units] roystervi:
might sound crazy but its common, have you check the side of the SD to see if its lock, also have you check another SD to verify that its just that SD your PD can't read?
[Android Head-Units] heaky:
Thanks shadowmike, you're right, after a couple of reboots, the settings are back in the bluetooth app and is working again!
[Android Head-Units] hamid_valad:
yup, it is not locked.

i checked my sd in 3 laptops and non of them can read it.

is there a safe way to un-mount the microsd from head unit?

(i turned it off, waited around 10 sec, then removed it)

do you think that the unit burned my microsd?

funny, my laptop at works, says it is 28MB!
[Android Head-Units] roystervi:
Then try in windows administrations tool and in disk management.

Check the status of the card from there. You can fix it in cmd. Look

On YouTube for "How to wipe and format with DISKPART" I can give you the

Instructions but watching the video you will be better. Using DISKPART will fix that problem. Let me know how it turn out.

---------- Post added at 07:37 AM ---------- Previous post was at 07:30 AM ----------

Are you running 2.8.8 again and did you upgraded back to the latest mCU? What I notice every time you do a software upgrade you are going to lose your BT. I was hoping you tryout what cool_head said about extra settings. Then that might fix every time we do an upgrade you will lose BT. I keep it in mind the next time I do a sys upgrade.
[Android Head-Units] shadowmike:
I did not see config info in extra settings.

Unrelated I lost root some how. I've been trying to figure it out.

On the broken sd is it a microsd ? I've had a pyn microsd litterally burn and melt a card reader in a laptop.

So it's hard to say, if your card is done, what exactly caused it

thanks man, i'll give it a shot. i'll definitely let you know.

i know you weren't talking to me, but i had the same issue. after the 2.8.8 update, bt didn't work. (no mcu update)

it was like the pics you posted.

but after a restart, it came back online.

i also don't have what cool_head said in my menu. (my mcu is very old)

yup, its a micreSD... when i put it in my pc, a windows dialog box shows, and asks me to format it, and when i say ok, it shows 28mb of space to format. and when i click on format button, it fails!!!

i think it is lost, it was 4gb, 5-6 years old!!

guys i don't like the 2.8.8 UI, (mainly the dock icons, nothing else changed, right?)

it's nothing like this pic:

(from wiki page, and for 2.8.6)

i like what i see in the above pic...

i liked the 2.7.29 version way more.

is there a changelog? should i stay on 2.8.8? can i go to 2.8.6? what r the differences? (i read about radio ui)

or maybe just use the 2.8.6 or 2.7.29 launcher?

changes apps coming up when pressing "mode" on steering wheel...

you can choose the most number / serial application button SOURCE / MODE.

and a sequel, you can now select a music player by default

i would love to have climate control app. (i dont know if it works on my car or not)

also have the grey launcher with my desired icon order.

change reverse cam lines

change equalizer background

change radio background

and (since i dont have an ipod, and never watch TV, and videos) remove them from "mode"

can any one guide me?

is anyone else interested?

my car has CAN bus, but i dont know why it connects to HU, the only thing it does, is to turn button back-light, when turning on my car head lamps!

any other use?
[Android Head-Units] shadowmike:
Climate control is in our units, your car needs to send the radio that info.

Just because your putting a smart radio in, doesn't mean your car will also turn into a smart car.

I can understand about not wanting so.e of those options cycling through.

Hey guys,

I'm selling my unit. Here it is. . I bought it back in April 2014 and is still under warranty, if that helps. Besides the traditional stuff that this unit comes with, I also have the following added, which the manufacturer modded for me.

- Red buttons instead of blue

- DVB-T

- 3.5mm mic output in the rear

- 2 USB ports in the rear

- I have also contact the reseller and they are willing to sell me a BC6 Bluetooth module for 25 USD. I can also purchase it and add along with the unit if you're interested in replacing the BC5 module.

- Everything from Torque Pro, iGO primo with ANS Navigator and all latest world maps, Next Launcher 3D, etc... is installed on firmware 2.8.8 and ready to go.

If you are interested or if you know someone who is, PM me for more details and a price. I'm located in the EU.
