[MTCB Android Head Units Q&A] DJCannonball:
i have some news!

i couldn't resist waiting for my seller to answer so i took a screwdiver and opened up my hu.

i took out the dvd-drive and kr3066 pcb.

At first i could not see anything strange or faulty.

i have cleaned the contacts of the cpu-som anyways with dry-cleaning naphta.

i made sure that i placed the board back into the socket properly aligned.

i also put the wifi antenna-wire thru an unused hole to the outside of the case. this makes a huge difference in reception.

after putting back the whole thing i installed it into my car.

i did several reboots, and after each reboot it checked the total amount of ram.

the total amount of ram is 1024 mb each time.

it seems to run flawless so far. it hasn't crashed once since disasambling.

i took some pictures to help others to better understand these android car headunits.

i hope that did it :fingers-crossed:

I didnt see the wiki first! Sorry!!

On the wiki is written: Telekom speedstick huawei

I found this:

HUAWEI E3372 LTE HILINK 4G LTE HSDPA+ / HSUPA/UMTS GSM/GPRS/EDGE

Model E3372s-153

And this:

INTERNET KEY HUAWEI E173

Is it the right one?

Edit

I figured out that the working one is the huawei e1750, so i ordered it. :) hope it works

Oh, another tip is to release the cables (at least on kld) the black part of the cable plug flips up, releasing the cable. Im used to the ones that pull out, so took me a while to figure it out.

Also, I think i found where we can hook up a fan. Someone else commented that their fan plug in under where the fan is. You cant see this plug looking straight down, but at an angle, there it is...

I've wired up my powered USB hub today and it's worse than before. I am not a happy bunny to put it politely.

Here's how it's all wired up:

The relay has a diode which is supposedly protection against power spikes or something like that. I snipped and insulated the red wire inside the USB hub as advised.

When driving along, the 3G dongle frequently disconnects and reconnects, it's much worse than before. However, the USB hub's LED does stays on so power to it SEEMS fine.

Dodgy USB hub? Dodgy 3G dongle?
[MTCB Android Head Units Q&A] typos1:
Excellent, so youve finally sorted your problems ? It seems it was just an incorrectly seated CPU card or something similar.

I dont know, I just asked you f the modem you were trying to use was one of the ones that is listed as compatible with these devices.

Lol it was me and I didnt just "comment" on where it was, I posted a photo with the actual plug arrowed, are you saying you took no notice ? ! :)

I dont remember it being really visible. Maybe it was dark or something was blocking the view or it was a shaky cam pic. ;)

Btw, do you know what the port is to thge right of the fan plug? Its accessible from the outside ( i think) under a cover secured with two screws.

Oh, for anyone else who wants to replace the antenna, I wanted to put down an SMT antenna jack on the board. The pattern doesnt support it, however it is predrilled for some through hole connector.

Here's my own dark, shakycam pic. ;)

Hi guys. I was told to come here with my questions regarding the unit I've just purchased. I haven't received it yet but wanted to know some things. I drive a Volkswagen Golf 2005. It doesn't have steering wheel controls or air con. The unit i bought comes with a canbus box. Do I need to use this or does the car already have one? Will I need to do anything to avoid battery drain to the car. Unit listed below.

I was all set to the the mod on mine when I first got it, but I didnt cos people can hear me fine, had no complaints, I also left a message on my landline calling form the car to hear it myself, there is room for improvement but I thought it was perfectly adequate so never did the mod, maybe clearchris felt the same ?

Thats a JY unit if your car has CAN Bus your ll most likely need a box, why would your car have one already ?? Unless someone has already fitted an after market stereo to it.
[MTCB Android Head Units Q&A] EvanKelly6:
Don't know much about canbus so not sure if they come with some cars. So the box that comes with the unit should suffice? Do canbus boxes need to be programmed or anything?

I have no idea what power the 3G dongle is, there are no markings. It is an unbranded item which was supplied by Pumpkin :(

I'll give the other USB port a go but I doubt that's gonna fix it as that would be too easy / too good to be true. Also, I have the Mobile Network Settings app installed, the 3G dongle does work, but randomly disconnects from the HU, moreso now I've done this USB hub mod.

Also, I've updated my diagram, I forgot the ground connection to the DC converter:

It does need programming but the factory will do it. If you want to know about CAN Bus, then Google or Wikipedia it. If you wanna know how to install an aftermarket head unit in a Golf 5 then Google that also, or try a VW forum, theyre very helpful. Once youve installed it if you get any specific problems related to your head unit ask here for help. :)

I really have not had a problem with the internal mic at all. I just have to turn off the blasting ac in the car because it makes too much wind noise. Maybe if I want to attach the external mic, but right now it seems like a lot of work with little payout. No one has complained about the sound quality and those I have asked said it sounds good.

I did solder it direct, just letting others know in case they want to solder on a plug.

The mods I want to do are adding a fan, and external control of power states. I want a nice, quiet fan and mouser is out of stock for a few weeks, so thats on hold. The external arduino project is on hold because the wrong breakout board for the SOT-23-8 chip I have. Apparently, the SOT-23 standard has different pin spacings and i need the .65 mm one. Should arrive from china soon and ill have an update on that.

I have considered the russian capacitor / usb upgrade, but I dont yet use the usb.

If it starts getting flaky on me, Ill replace the caps, but Im holding off on that for now. In related news, I got a good look at the through hole caps, and they are labelled for -40C through 105C, so thats good news.

Car head unit with RDS Traffic Announcements

Hi All, New to this forum. I used to have one of these Chinese no-name Android head units in my last car (from Easyrising on ebay). I had mixed feelings about it mainly because although it did all the Android stuff very well, it was rubbish at its primary function which was to be a car radio.

The radio reception was very poor, losing signal very easily and not finding it again without manual retuning. I suspect this may be partly down to the antenna in the car, which was a "Diversity" unit (VW Passat), so I am willing to give it the benefit of the doubt.

However another thing that really annoyed me was that although the unit claimed RDS functionality, it did not give the RDS Traffic Announcements that the stock radio did. It showed the radio station name, but did not switch to local radio station to give the voice alerts.

So, I am thinking of dipping my toe in the Android Car Stereo water again, but am looking for recommendations.

Do any of these Chinese units offer the RDS TA functionality?

Is there an App that can be loaded that does, or is it a hardware issue?

My current car (an Alfa 159) has a 2-DIN aperture and steering wheel controls, so I want to be able to use those. The Alfa has a beesting aerial on the roof, so I am hoping that this will give better reception. I do not know if it is amplified.
[MTCB Android Head Units Q&A] ga!nusha:
They all have TA functionality. I have never tested it. Actually i've used the radio twice as most of the times i use spotify. You can't load any other Radio apps.

People are looking for some alternatives but since it is controlled by MCU i highly doubt that any solution will be found.

In order to use the steering wheel controls you need to get a unit that has an alfa romeo canbus. Otherwise it won't work.

If you decide to buy it i higly recommend buying an external(on wire) FM amplifier to use with the unit. It does miracles.

I have something similar to this:
[MTCB Android Head Units Q&A] Orlinon:
Thanks for the reply. The unit I had had a TA button, but it did not function as I expected to (and how every other standard car radio I have seen does). When I pressed the TA icon on the screen, it retuned the radio to the local radio station. On other radios I can listen to one station then the RDS switches to the local channel when there is an announcement. When the announcement finishes it switches back. This is particularly useful when driving long distances as I can listen to a national station, but get local traffic reports.

The aerial in the Passat was amplified and I had an adaptor to pass DC down the coax wire to power it. The problem I think was that OEM unit has built-in electronics to switch between two aerials depending on which one gave the best signal. I think the aftermarket splitters just use one of the aerials, so the signal is never as good.

Also, I forgot to mention I'd also like DAB, but none of these Chinese units seem to have it.

yes, I do it but in recovery mode I can not select option flash on sd card ... because to select this must long press on power button and power button have not function.

[MTCB Android Head Units Q&A] typos1:
We dont know for certain he HAS flashed the MCU as well yet and its no big deal to reflash the correct MCU, but you ARE right, way too many people dont read the first page or search the thread before posting !

---------- Post added at 03:00 PM ---------- Previous post was at 02:57 PM ----------

Ah, of course, its only no big deal if your buttons still work somehow - usually if you flash the wrong MCU the button order is messed up and if you have knobs you can still use them, if youve got a knobless unit and a mouse doesnt work, then it IS a big deal, not sure what to suggest here.

What updates exactly did you flash ?
[MTCB Android Head Units Q&A] dobrescu:
I flash this update: "4.4.2 Klyde Kitkat for 800x480 screens, prerooted, debloated, 3GB data partition - Source: coppertop2000" when I loose button functionality. After that I flash with my pc android 4.2.2 - "KGL(20140827)".

Now, I have MCU GS 2.20 and KGL(20140827) android. Somehow, I don't know exactly how, I flash MCU GS 1.90 but don't win the buttons functionality.

Any ideea?
[MTCB Android Head Units Q&A] kaween:
I know for a fact my AN21-U's TA works.

Even when you're not listening to the radio itself but are listening to say Poweramp and your MP3 collection, it will chime in and let you hear the TA info as long as the radio station transmits it. The unit will _not_ show the Radio app at such a moment -unless of course you were actually using the radio app-, the TA happens in the background. Once the TA is done, the mediaplayer will continu. Selecting the "reg" setting prohibits the radio to throw TA info at me about some problems at the other side of the country.

I would be surprised if the Rockchip-based units in this thread wouldn't do exactly the same thing ?

As for DAB .... I'm going to experiment a bit with that myself the moment I get my DAB USB receiver, but the issue is the pretty crappy UI's for the DAB-tuner APK's I know, so it's more a "lets see if I can get this to work" kind of thing.
[MTCB Android Head Units Q&A] dobrescu:
I try to overwrite files in /system/usr/keylayout with fx explorer but no alow to do this. Yet, that is the way?
[MTCB Android Head Units Q&A] typos1:
All units have RDS functionality as mentioned in any listing selling them. Pretty much ALL Android headunits have RDS AFAIK apart form the Newsmy NU3001 (and even that is capable it just wasnt implemented when I last checked).

I have one in my Alfa 147 and the radio is good, you dont need booster, you need a power injector the same as you do in the Passat as I m pretty certain that the 159 has a similar set up to the Passat and my 147. I havent tested the TA function however, but I can try to later for you.

DAB is not available. However you can get digital radio if you order a unit with digital TV as digital radio is broadcast on DVB-T. For a decent signal you need a diversity (dual tuner) tv card or box. This is not actually DAB, but it IS digital and the compression method (MP2) is the same as DAB, so the sound quality is exactly the same ie rubbish compared to FM. Thats assuming youre in the UK where we only get DAB, in the rest of Europe there is DAB+ which uses AAC compression and is much better, though still not as good as FM sound wise. Or there is the Dension device in the link below.

Some of these units use the same radio IC as the AN21-U, so its highly likely that on those at least TA works in the same way.

Which tuner have you got ? A combined DAB/FM/TV one ? Dension make a couple of DAB devices that controlled by apps, which you can then install on you headunit, one uses BT no idea if it will work with the BT card on these units :

http://www.dension.com/product/dabp

http://www.dension.com/products/dabu

Did you ONLY flash the Android update or did you flash the MCU as well ? I ask because your problem is the sort of problem you get if you flash the wrong MCU.

The MCU controls the button mapping.
[MTCB Android Head Units Q&A] Orlinon:
Thanks, I'd appreciate that. Like I said, the RDS worked to show station names but I never got the TA to work. Have to admit I didn't try a great deal because the radio reception was so rubbish. I used TuneIn instead tethered to my mobile.

I did have a play with the Wavesink app (on Google Play - can't post the link as a Newbie :( ) with some success, but the UI needs a lot of polishing.
[MTCB Android Head Units Q&A] kaween:
... and the fact the development of Wavesink has more or less stopped and they don't react on requests other than "we know this is an issue " .... not a good sign.

I know at least 2 people who ran the Usb Dension thing that "responds like a mp3 stick", essentially you use this device as it mimics mp3 files and dumps them into your unit's mediaplayer. Neither of them recommends this device, as it operates quite cumbersome and has a problem with frequencies (at least in Europe) where the Dension "looses acces" to a whole range of freq's after a while.

[MTCB Android Head Units Q&A] gazdaaa:

Sounds like it needed a booster for the antenna.

That is not the only DAB device Dension do, there is another BT one which sounds better but dont know if it would work with BT on these units.

Search the thread, CAN Bus adapters come with units designed to fit CAN Bus cars, you will need a CAN Bus adapter if you buy a universal unit. For more info use the thread search function, there are lost of posts about it.

---------- Post added at 07:59 PM ---------- Previous post was at 07:58 PM ----------

It may not be "a matter of 5 minutes" - what if there are no TA announcements for a few hours !?
[MTCB Android Head Units Q&A] gazdaaa:
Of course, but when it transmits it is below 5 minutes, here in Croatia we have TA every hour in few langauges (esspecially during summer).

When I get the unit, I would like to contribute to this thread and community by entering those rare Q&A in the wiki, because this units are much better than NU3001, by my opinion.
[MTCB Android Head Units Q&A] typos1:
Well, the MCU is better than the NU3001, more developed, did you know there are RK3188 quad core versions (same processor as the NU3001) available now ?

In the UK they are sent when there is a problem with the traffic AFAIK, although I guess they might be sent just after the news when they have the traffic reports as well, I ve only ever used TA occasionally.
[MTCB Android Head Units Q&A] peti007:
I have the same HU as you. You say FM amplifier "does miracles". On the picture you linked in there is no female antenna socket, just the male plug on the wire. How does it works?

Has anybody got one of these? How it works?

Because Klyde didn't answer me after the Paypal's protection left and the canbus decoder not suit for my car perfectly, I'm looking for a canbus decoder too. I found this webshop:

http://www.tradesolution.hk/e/ptxwebstore_product/2140.html

[MTCB Android Head Units Q&A] matekhr:
Yes, but also for S90, S100 and S160 units.

That's why I believe they will work with most Chinese units.

Here's one of manufacturer's page:

They offer a wide variety of can bus decoders, but not mentioning any matching headunits.

I believe the "output lines" (Tx, Rx) are designed according to (some) standard.
[MTCB Android Head Units Q&A] typos1:
Yeah, I think [MENTION=6041319]dsa8310[/MENTION] or someone else said that about an antenna booster, it needs a static filter to workd properly. The cylindrical power injectors that ARE NOT booster, do actually have one inside.
