(comes out of the shadows)

*Rant Mode ON*

Somewhat off-topic, but I find it incomprehensible all these units, new and old, neglect including a really usable radio app. :p

Lets be serious : It IS in first place, a radio, isn't it ? But a somewhat logical and cleanly made Radio app interface ? Few and far between. RDS support ? Even fewer. Radio Text ? Only ever saw ONE unit (the AN21) that includes that, and I find that an extremely depressing state of affairs really.

Of course, I'll probably get blasted by tons of people saying "yeah but I rarely use the radio anyway" but even if so, there's NO technical reason why these units can't do stuff that ANY sub 80 USD car radio incorperates as no-brainer-standard-issued-functions for the last ... I don't know, 10+ years now ? (other than lazy programming and non-existant customer care, that is).

I didn't buy this to have a radio. I bought this for an entertainment center in the car

I've bought CD players that don't give you anything but station number and track numbers.

So to me, it all depends on what you actually want. I replaced a cassette player that only displayed time, so .... This radio is a 1000000x better than what I had.

If you had a car that had a fancy radio in order to help drive sales of your car then I'm sorry

But my car was sold for the car they didn't need special radios and gizmos in order for people to want it

My crappy hui-fei unit already has android kit-kat and the radio has RDS with radio text.

Look at the picture attached.

I am lost and I really don't understand what your ranting about... this treat is about the AN-21 U. The AN-21 U does have RDS support. The AN-21 U plays music, seek working now, RDS, have presets, and has a 18 preset stations. How ever if you want to rant then I will rant that my unit does not play AM radio. maybe I have not see that is this treat BUT I WILL LIKE TO ASK IF ANYONE OUT THEIR AM RADIO IS PLAYING PLEASE LET ME KNOW.

[Android Head-Units] cool_head:
Before the kit-kat update, the unit didn't have radio text. Only RDS.

This 2 units are just for playing around. I'm driving with my old RCD300. ;)

This is an Hui-Fei head unit.

In Portugal only have FM radio. Don't really know if AM works.
[Android Head-Units] shadowmike:
The radio this replaced was 23 years old, did t send signal to front passenger speaker and didn't get am or fm signal.

I still don't use the radio, as I didn't even connect the antenna.

If radio was that important I would just loop the same 6 songs

I do agree that all features should work but little things like radio stations and song name are nothing compared to it booting up, outputting sound, touch screen working, etc.

If my girlfriend or wife had that much of an issue I would go to Wal-Mart buy the **** Pioneer DVD player and a week later, reinstall the an21 because of the actual features.

Teach her how to WiFi tether and use spotify or Pandora.

Again I realize everything should work, but somethings I'll allow to not work because I don't use it.

But let's be honest... There's no reason for us to even think about upgrading a car stereo if the manufacturer would actually use decent stereos in the cars they sell for over 20,000

hey guys, it's me again! sorry!

i couldn't find a way to reduce MODE/SOURCE cycle. can anyone help? (i just found a link in 4pda, which was broken!)

also, i found out that there is an option to show which door is open. (in some cars, i know!)

but how does it work? when someone opens a door, it shows on the screen? like showing the reverse camera when putting the car in (R)?

also my car has TPMS, again i saw a link that said it has the ability to show it on screen. can anyone guide me?

does it all work with CAN bus? cant we send these infos ourselves?

i'm tired of google's BAD translation. and i cant find any thing.

Can someone please help. I am trying to update, and I have gone through the forum but cannot update successfully. I have the updated unit with the single silver knob on the left. I have downloaded the 4 update files and placed on the root of a sd card, but the unit will not update. When I select the update process from settings the unit reboots and then says "update start" and immediately says "update end." I have tried two different SD cards. My current firmware is 2.7.3 which is what it was shipped with. Am I missing a simple step somewhere? Any help is appreciated, thanks.

[Android Head-Units] donaldta:
I wouldn't worry about the native USB ODB2 adapters from Scantool.net website. They are pretty well known name brand. As far as I know they are all using a real FTDI UART adapter, unlike the Chinese clones that you might get from eBay. If the response from typos1 that Ian said it also must be FTDI compliant then you won't have anything to worry about since you using the AN 21-U with USB Java APIs. Besides, I wouldn't be surprised if Ian got a little help from them since his app is one of the few ODB tools on Android that can toggle Scantool's power savings mode on the OBDLink MX/LX adapters.

The only Serial to USB adapter on the site that isn't using FTDI is the Prolific USB to RS232 Converter. While you can use it with any of their adapters that has the RS232 port, you'd really have to go out of your way to buy it. I guess it would be handy for those that only had kernel modules for Prolific serial drivers. Though with the feedback relayed by typos1, I now wonder whether or not Torque's libserial_port.so supports Prolific or not.

Maybe it is because you extracted the files from the archive? Most Android devices I have used looks for the archive's filename/extension. Not the files contained within.

Unit on ebay

I know everybody is buying this unit from this guy Peter Chen but I bought it from this guy :http://www.ebay.com/itm/New-Android..._Dash_Units_w_GPS&hash=item1c39ec6aca&vxp=mtr and it was $299.00 with free shipping and it got here in 3 days from China with DHL. This guy seams to be a lot cheaper than Peter.

[Android Head-Units] chris.r.r:
According to [MENTION=1915855]KID52[/MENTION] the files should be extracted...

Yes ;) the brown one, but I don't take any responsibility...
[Android Head-Units] KID52:
I only mentioned Bluetooth adapters because some people expect to be able to use them.

Interesting, the files definitely need to be extracted and put on the root of the SD, does not matter what other files are on there as it knows what to look for.

Perhaps you can ask your seller for the update, maybe your system is different to the universal one. Who knows!

Some people have purchased for this price on eBay. However it was reported that certain sellers would not ship to Europe, and those that did want around $85 extra for shipping. The unit is also missing the TV tuner. But this has been discussed many times in this thread already, and is mentioned in the first post...

I just purchased this usb OBDII http://www.ebay.com/itm/130774966487?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

Will this work with the unit? I'm rooted if that helps. Also where will I plug it in? put a usb spliter where the wife dongle is in the back and connected there? Thanks
[Android Head-Units] MynticeLX:
I just recently installed this. It had the latest software updated. The problem I have is that for some reason, it seems to have an issue where the screen will go from White to Gray to Black and then not be usable on boot. The bootscreen doesn't show, etc. Essentially, I have to disconnect the battery to get it to boot up again correctly. Then, once I do this - it will work until I turn the car off again and it will go back into the screen not working. Any ideas?
[Android Head-Units] donaldta:
You'd need a USB hub to support more than one USB device. I'd personally recommend a self-powered one as opposed to a bus powered one. And whether that particular one will work, you never know. You can't tell by the pictures or the items specifications which USB to Serial adapter it uses internally. Buying these ODB clones off of eBay is like opening up a box of chocolates in Forrest Gump, you never know what you're gonna get. At least it is cheap, so you won't be out too much if it doesn't work.
[Android Head-Units] sorin129:
Thanks I guess I will see if it works when I get it. As far as the USB hub. This is the one that I got http://www.ebay.com/itm/190649674771?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 Will this one work? Just for the OBD and the wifi dongle that is connected right now in the back of the unit?
[Android Head-Units] KID52:
I have that USB hub, it works fine.

Some of the cheap eBay USB OBD devices use a Prolific serial to USB converter chip, or at least in my experience that has been the case. One of my devices has a PL-2303HX chip.
[Android Head-Units] donaldta:
That's a bus powered hub, so as long as the sum of the the USB device's power draw remain below what the USB port can handle it will work. By USB 2.0 standards that's 100Ma @ 5V, I'm not sure what the specs are on the AN 21-U port. However, if your USB devices draw more power then what it can handle then you'll get not so great results. That's why I usually recommend self-powered hubs for automotive head units, like the Startech's ST4200USBM or ST7200USB. Especially, for those whom might consider using a portable USB hard drive in the future.
[Android Head-Units] sorin129:
Thanks so at least I know the hub will work. As far as the OBD I guess is a crap shoot. Anybody on here has a USB OBDII that is confirmed working on this unit with Torgue Pro? I hate to keep buying them and not know if it works
[Android Head-Units] pgarrity18:
I went ahead and bought that USB hub (7 port version) and I am purchasing a 12V to 5V stepper and a DC power connector so I can just hook it right up to the 12V power wire in my vehicle. I haven't installed this yet, but I believe it will work smoothly and be much cheaper.

I can;t post link, but here are the exact names on ebay...

ebay search:

3 pair Male Female 5.5 x 2.1mm DC Power 12V 24V Jack Adapter Connector Plug CCTV

Waterproof DC-DC Converter 12V Step Down to 5V Power Supply Module 3A Max 15W

thanks ... as per the other posts, why not hooking up Key-2 to my cars SWC- ? I would have thought that both wires from my car need to be getting signals.

thanks ... I have been researching and looks like the car has resistive system. If I just hook up the Key-1 to SWC+ and if I am wrong, would that damage anything?

Sorry guys ... Im still confused about Key 1 and Key 2. If I am correct about the SWC system in this car and its resistive, would I not hook up SWC+ to Key 1 and SWC- to Key 2 ?

I feel like i am getting closer but not there yet! again, all help is appreciated and thanks in advance!

So, i got mine today (4 Days from Honkong to Austria :good:). I´ve got to pay import taxes as i expected, but the unit was at $ 300,- plus now $ 80,- what is cheap altough.

I played with it the whole afternoon and did a root and update. Everything works as expected, except Navigon. The software works an routing is possible, but i cant get any sound from it. Google Navigation gives sound, but i want to have good offline cards for Central Europe and a software, my wife could use easily. Sygic and TomTom failed both (one delivered with the radio got installed, but had no cards and didn´t let me download them).

I can live with the radio app but it´s a shame, that no cover pictures come up on the iPod app altough every album i have has them with it.

Another "Problem" is the DVD part (which i think i will use once a year ore so...). DVD´s are played in english and there is no option to change the language. The problem on it is, that my english is not good enough to understand a whole film...

I ordered mine whit external microphone and got what i wanted. The microphone cable comes out with that harnes, that has the ipod and auxilary input with it. If you look at the harness from the side where the cables break out, it is the fourth contact on both rows, counted from the right side. Upper site white and the down site the black cable. I dont know if there has something to be connected within the unit. Tested it with the internal mic and connected the external mic while speaking. It switched promptly to the external microphone and my telephone partner said it got very clear and good to understand.

So i will put it in my car as soon i got the adapters and know if my steering wheel controls are swc or if i have to buy an can adapter (2001 Ford Mondeo TDDi).

I´ve got my unit from here: w.aliexpress.com/item/6-2-inch-Multimedia-Car-DVDCar-Radio-DVD-Players-Android-4-1-Car-GPS-DVD-Car/1504400297.html

Emely Lee is a nice one and she can tell you, which wishes can be done and which not. She gave me all answers to my questions and we had some nice conversation. I for my part can recommend her as seller. Perfect service (until now) and a very quick delivery paired with a good price (no, i do not benefit if one of you order there ;) )

Greetings from Austria

Edit says: i got it working! I have now speech on my Navigon App! I installed the Google TTS from the Market (hxxp:play.google.com/store/apps/details?id=com.google.android.tts) and made it to the standard tts.

The only thing is now with SU. It says it´s out of date but the update does not work direktly. Does someone have a link to the current version?
[Android Head-Units] sorin129:
I need help too. I have a 2004 Chevy Avalanche and don't know exactly which wires to connect for SWC. I know that the wires from the radio Key 1 and Key 2 are for analog and CAN Tx and CAN Rx wires are for digital but I don't know if my car is analog or digital and also which wires from the car to connect. Anybody can help me?
[Android Head-Units] donaldta:
I would still use a multimeter to find out unless you can get a copy of the schematics for your car's SWC. Here's the thing. I've seen "internet resources" that claims a car is resistive yet its actually voltage. Technically both can be correct because the car manufacturer is using resistors to change the impedance. But, we don't necessarily know if it is impedance to Ground or a Voltage Source. That's why when I refer to them as analog because each button pressed is assigned a discrete value (although sometimes the values are duplicated over different wires). The problem is that you do not know how the wires are hooked up in the back end. Is there a 12V or 5V source feeding the wires? Is it grounded? or are the wires looped?

So... let me give you an example:

Positive Voltage Scenario:

12/5V ---> Switch (Play, Pause, Rewind, Fast Forward) ---> Resistor(s) ---> Car Wire #4 ---> AN21U Key 1

12/5V ---> Switch (Volume Up, Mute, Volume Down) ---> Resistor(s) ---> Car Wire #17 ---> AN21U Key 2

Grounded Resistance:

GND ---> Switch (Play, Pause, Rewind, Fast Forward) ---> Resistor(s) ---> Car Wire #4 ------ AN21U Key 1

GND ---> Switch (Volume Up, Mute, Volume Down) ---> Resistor(s) ---> Car Wire #17 ------ AN21U Key 2

Resistive Looped:

AN21U Key 1 ---> Car Wire# 4 ---> Switch (Play, Pause Rewind Fast Forward, Volume Up, Volume Down) ---> Resistor(s) ---> Wire #17 ---> GND

The first two scenarios you would use Key 1 & 2 because the different wires carry separate signals for each button. I would be highly cautious if the wire is fed by a 12V source because again, you can end up frying the SWC adapter. In the Grounded and Looped scenario is it not as dangerous. The last Kia I helped to install a head unit was a Soreno and it was the last scenario; looped.
[Android Head-Units] sorin129:
Do you know which one is for 2004 Chevy Avalanche and which wires I should try to test or connect?
[Android Head-Units] donaldta:
This is how I cheat when I don't have the shop manual. I use the Axxess database to see which pins are responsible for the SWC wires. Checking the different models of the 2004 Chevy Avalanche they all link to 2003 shell pin 1 wiring instructions. It shows pin #A1 would be connected to their ASWC-1. These means the A1 pin is where your SWC signal is going to, and since they use the pink wire that probably means that it is positive voltage so check with a multimeter to see how much if any of them measure greater than 5V then I would recommend using a voltage divider so that the highest voltage falls below 5V.

EDIT: I'm sorry, I double checked my notes. Axxess ASWC Pink wire is Can Bus High and Pink/Blue is Can Bus Low.

Btw, I should point out that I have never installed an AN 21-U. So, I am not 100% if it supports positive voltage SWC. I'm really giving them the benefit of the doubt that their SWC module is autosensing.
[Android Head-Units] omarko:
thanks for that insightful post !

you just made my head spin !!!! hahahahaha

also, I found access to all car schematics. Its on the www.kiatechinfo.com website. One has to register to get access but that takes 2 seconds. Any chance you can look at this ? just select Rio 2012 UB and then click on ETM which will take you to wiring schematics. I am searching through it atm for the steering wheel controls but no luck yet. has to be there though.

You start out from the assumption that I live in a region where this route could be considered a viable solution, my friend.

Sadly for me, that's not the case.

In terms of cost, a dataplan to accomodate for this would easily cost more in one year than the unit is worth. Call me a haggler if you will, but that's totally unacceptable to me.

In terms of usability, the coverage is totally unsufficient to permit an uninterrupted radio service either.

As these parameters do not pose any issues to you, I can only imagine both coverage and datacost situations are totally different in your corner of the world and I'm happy for you.

[MENTION=4736782]kaween[/MENTION] my cousin buy this Pioneer AVIC-Z110BT brand new 2005 he paid $2400 install. today on the website ( http://www.pioneerelectronics.com/PUSA/Car/GPS-Navigation/AVIC-Z110BT ) they still asking Suggested Price: $1,799.00 for it. every rant you are taking about this radio has. I can sell it for you for $1600.00 if you want it. With all your rand this radio at Suggested Price: $1,799.00, our unit at $250 - $350 still out shine the top brands.

The Pioneer AVIC-Z110BT and the Pioneer brand is a good radio but, it does not have the freedom as our units.

there no free upgrades, no addons and after Pioneer release a unit, they only do one or 2 upgrades for that unit and its not free then your on your own. The Pioneer AVIC-Z110BT boot very fast and all but again no upgrade. This radio upgrade cost $150 on amazon and more on Pioneer website.

I took it out of my car and replace it with a AN-21 U for $265 and my Android out shine it. I can get on the web, play every type of video. the Pioneer AVIC-Z110BT ay $1700.00 can only ply 4 type of video. look at my pic below and I can sell you my Pioneer AVIC-Z110BT that the RDS and BT phone work very well.
