Where I would love to go through the entire thread, there is not enough time to get away with it. So what is the final call on this type of radio? I have a 2003 Ford Expedition and since I do a lot of driving, I though replacing the crap stock radio with one of these radios would be great and geekish at the same time. I would love that once rooted, I could access to the play market with no restricts on the apps that I pull down. Secondly, I have enjoyed playing with OBD Doctor on my Note 3, so it would be nice to be able to run it on this device. It would seem that doing bluetooth dongles are still a no go... It would be nice to be able to use a 4G dongle, but I have yet to find that.

Question of the day, it is worth purchasing or should I wait until the Chinese come up to speed?

---------- Post added at 11:51 PM ---------- Previous post was at 11:50 PM ----------

Is there a link so I can see the specs on the radio?
[Android Head-Units] jakejm79:
You will need one with the same (or extremely similar) SoC not just the same core processor(s).

Is anyone else running System Version 2.6.62 unable to take screenshots? Not working for me.
[Android Head-Units] pgarrity18:
If you read through how he does it, it requires having access to the radio to extract symbols and such. I have yet to receive mine, so I have that thought (and many others) on hold...

On that note: My seller sent me a UPS tracking number 5 days ago, saying it would be trackable in about 3 days, still shows not found... has anyone else experienced something like that?[/QUOTE]

Same thing happened to me. They said that fedex would not take the shipment and that they had to switch over to DHL. They gave me a new tracking number and its location is being tracked as expected.
[Android Head-Units] sciallo:
Thanks, Are you in the US? who was the seller?
[Android Head-Units] mcsvt:
Just to comment to a few things on the past few pages. I purchased mine from pumpkin, which was delivered by DHL (I'm in the US), within a few days. It came with an ISO connector attached to the wires which I cut off.

Definitely use the AUX or TV app prior to root, I didn't and it was near impossible to finish it, but if you pull down the notification bar and flick it back up you can momentarily see the icons and screen. Using the newest root I still needed to use the terminal to delete the local.prop file.

Since putting it in the car I've only driven that car a few times, but so far I like it. The iGo nav is pretty good too, just need to figure out how to get it to MPH... My iPad2 works fine through the app and I can tether it to my GS3.

One question is, will a launcher let me change the horrible normal home screen with the radio/nav/tv etc none android icons?
[Android Head-Units] kmtk:
I tried Nova and ADW, both worked nicely. Not sure what I'll go with for daily use, I'm still running the unit on my desk until I get a harness.
[Android Head-Units] KID52:
Works fine for me. I am not sure where they save to though.

This is why it is part of the guide as mentioned a few posts ago :)

When you install iGO it asks you if you want to use miles or kilometres. You can change this again in the settings menu.

Yes, ADW launcher is very good and customizable.
[Android Head-Units] chris.r.r:
I finally received my unit from Peter Chan.

I tried to power it on on my desk with an old PC power adapter. To the quadlock adapter of my VW unit leads a thick yellow cable, which I connected to 12V, and a thick black one to ground. The unit does nothing, shouldn't the two wires be enough? Did I miss something?
[Android Head-Units] KID52:
Yes, you missed the ACC wire. This should be a red one, needs to be connected to 12v also.
[Android Head-Units] kmtk:
Grab a molex connector. Twist the battery positive (B+) and ACC wires together. Insert both in a 12v pin on the molex (yellow). Insert the ground in a black pin.

Also short the ATX connector to power on the PSU. I put a wire in the green Power on pin and another on a ground pin.
[Android Head-Units] Defender666:
Same thing happened to me. They said that fedex would not take the shipment and that they had to switch over to DHL. They gave me a new tracking number and its location is being tracked as expected.[/QUOTE]

This is typical chinese when they don't have the device in stock, they send wrong tracking numbers to keep the buyer calm.

Normally after a few days they send then correct number saying: "DHL changed the number..."
[Android Head-Units] mcsvt:
I had originally thought the revised root program fixed that, but obviously it didn't :)

Ah, iGO was already on my unit, I'll have to dig around more, I haven't seen the option in the settings so far.

I tried ADW today, much much better.
[Android Head-Units] KID52:
Does the sound, by that I mean the voice, work in the version of iGO that was already installed?
[Android Head-Units] mcsvt:
Yes the voice announces when I'm over speed limit (do see the option to disable that) and turns.
[Android Head-Units] KID52:
Interesting.

You wouldn't believe how many versions of iGO I downloaded before I found one that actually worked fully. It seems the voices not working is a common issue on Android 4.1. I have yet to get TTS voices working though.
[Android Head-Units] chris.r.r:
Thanks for your replies. But I can't find a red ACC wire, which I could connect to something... There is one, which comes out of the CAN decoder box, should I use that one? But then I have to disconnect the decoder box... I'm seriously confused ;)
[Android Head-Units] KID52:
Yea, the ACC wire is the red one with the fuse on it going into that box, if it's sat on your desk rather than your car, just disconnect the box.
[Android Head-Units] sciallo:
+1 one thing you can do is unclip that black fuse box and apply 12v at the fuse (away from the unit to be safe and keep the fuse in the circuit)
[Android Head-Units] kmtk:
This is an excellent recommendation, it made many apps readable without getting right up to the crappy screen. You can also use the module to change how large icons and widgets are by changing the settings of the launcher (ADW in my case). I also found most widgets unusable, this helped immensely. Thanks, I think this is a must have mod.
[Android Head-Units] patrickoneal:
I didn't even think about altering the launcher, I'll have to give it a try. I still haven't installed mine in a vehicle, I've got too much going on, but I'm definitely going to mess around with it a bit more before I do.

[MENTION=1426977]kcallis[/MENTION] :

In my opinion, yes the devices are worth buying.

They're however NOT meant for people who fully expect a 100% P&P solution and expect a 100% fully tested and matured device. If you want that, wait or spend money on a high-brand device that will cost you double and perform at MAYBE 25% of the capabilities of these Chinese droid devices. But you will NEVER get the same kind of brand support on these devices like you would with some Pioneer of Sony device. How much you're willing to pay for that is up to you. :)

OBD operation is very much possible over BT, but it depends on the flexibility of your seller really. Ask if he is capable to fit the unit with a BC6 board, because that is what you need to do that. Many sellers will add that board to an Tonghai Create-based board for 15USD if you ask them. While your at it, ask for an external Mic mod : some will do that for free, other will ask 10USD or something. If you want a workable handsfree solution, this mod is totally worth it.

Realise however that when things would go south, you're pretty much left to your own devices. There's enough of helpful people on this forum that will try and help you out as good as they can, and the chance you'll find the answer to YOUR questions will have been posted in the past here already. But when the device would fail in terms of hardware, don't be afraid to solve it yourself. Even the mainboard isn't that expensive anymore (I recently found a seller for this board asking 65USD) meaning that when it would break, the cost of repairing it yourself will probably be lower than the return cost for the unit. Plenty of info on this forum about how to rip this unit apart and how to modify the unit to your needs (alternate power circuits, mic modifications).

The seller I'm refering to MAY be willing to sell the BC6 boards too, I've seen several people asking for just that part to retrofit their units with OBD support : I'll make sure to get to the bottom of that as I've seen that question popping up quite a lot here.

They are pretty friendly, but their English is a bit .... iffy. If you have specific wishes or questions, be sure to double check their answers. :angel: I'm not doubting their honesty, but my communication with them was a bit difficult. I think forum member Zexxgx bought his unit from them, and he's pleased with the unit as far as I can tell. And those guys are currently giving a serious discount on these units too.
[Android Head-Units] Ackms421:
Yeah, I just bought the second one you listed and should receive it soon. Seems incredible for the price compared to (like you said) the prices and capabilities of other options. Does anybody know how the GPS is on this one? That is one of the main reason I want it, Google Maps!
[Android Head-Units] kaween:
Yeah, a bit of shopping goes a long way on these devices. I myself was very tempted to buy one of these dvd-less devices myself, but the amount of rework I had to do on my dash was just too much as the clearance of my dashboard is just too small, and sadly I don't have access to a laser or high pressure water cutter. :(

The GPS part of these units are pretty much identical on all TH-related designs as they are reside on the CPU board which is identical independant of used MCU so far as I can tell.

I can't complain about reception quality. GPS fix happens fairly quick (it has found its fix most of the times when I drive out of my underground parking and the first turn of the road, approx 80 meters from my parking space - so that's a couple of seconds after leaving my parking space).

I don't use google maps myself but it does work, and the reception quality is independant of used program.

I've put the gps antenna invisable in my dashboard : the magnetic base of the antenna allowed it to be fixed on the metal tubes of my air ducts. From there, the antenna only has a thin piece of plastic (the dashboard itself) and the windscreen above it. It's interesting to see exactly what has influence on the signal strength and what not : for example, my wallet placed directly above the location of the antenna has no influence at all, a stack of papers or a piece of plastic : same thing. But a sack of fluids or organic material (my hand for example) diminishes the signal strength by at least 40%. A sheet of metal (as expected) even more so.

As the AN's are capable of using the GPS info to enforce speed dependant volume control if the user wants, the're more than one reason to try and get a as-good-as-possible reception quality on these units.
[Android Head-Units] Ackms421:
Thanks for all the details. Sounds great. The second one does not have an external GPS antenna though, right?
[Android Head-Units] kaween:
Euh ? ALL units have EXTERNAL gps antenna's. I've never seen a unit with an "internal gps antenna". It would be commiting "signal suicide" to put a GPS antenna in a 2din sized metal box .....

The plug for the external antenna can be seen on the pictures, it's that golden MCC plug next to the audio stuff.
[Android Head-Units] Ackms421:
On the second unit you posted, this one?

http://www.aliexpress.com/snapshot/6268852172.html

It says GPS is built in and I don't see the stuff you're referencing. Am I missing it? I don't see a GPS antenna anywhere on that page.
[Android Head-Units] kaween:
Yes you are. The picture with the pigtail (the cables). Take a look at the row of yellow cinch plugs. To the left (well actually RIGHT as the unit is pictures upside down there ...) you can see the GPS antenna connector. It's even labeled "GPS". :laugh: The "gps is build-in" refers to the fact the GPS chip+receiver is inside of the unit. There are units that need an EXTERNAL GPS BOX as the gps-logic is not integrated in the unit.

But on an's, the GPS chip is on the ARM daughterboard.

The antenna itself however is connected externally.

As said, there's no way to have a good reception of a gps signal if you put your antenna in a metal box. No manufacturer will be so stupid to try and get away with that, and that's a good thing too.
[Android Head-Units] wanxu:
Hey, any way making a backup before trying to update to 2.8.3? I don't want to loose Optical Parking System or anything special that could have the unit.

My unit is 3 days old and I feel I need to update it :P

MCU: 4.3.7-22-10-ES00201

System: 2.7.38
[Android Head-Units] kaween:
Top of my head : root first, titanium backup second. Should work.
[Android Head-Units] Ackms421:
Yep, I see it now, thanks. Is that something I need to purchase separately? The antenna I mean.
[Android Head-Units] kaween:
No. It will be in the box, don't fear.

It wil be a little plastic black box, approx 3x2.5x1,5cm big with that MMC connector and typically a magnetic base.
[Android Head-Units] Ackms421:
Okay, awesome, thanks a lot. What did you use to root it? Towel Root?
[Android Head-Units] wanxu:
Thanks, so using Baidu root.

How can I be sure my unit is one of these and there is no risk in a brick?
[Android Head-Units] wanxu:
One more question, guys. What is the behaviour of "recents" and "menu" button in your units? In the top-right of the screen (notification bar) there's a recents button, however, it works like menu button in my case. My unit doesn't have physical menu button, so when I open a full screen app I can't access the menu. Any way to solve this?

[MENTION=4521853]Journeyman91[/MENTION], I have mine since last thursday and I am in the same System version (2.7.38). If you look in this thread, it seems there is a new version: 2.8.3. Didn't try it yet.
[Android Head-Units] ZexGX:
The RCD310 doesn't have a traditional 2-wire +12V input like this headunit (and nearly all pre-CANbus headunits) is wired for, but it does have CANbus high and low inputs. My guess is the CANbus adapter (since these headunits do not have CANbus natively) for these headunits does not have control over the system when the ignition is off, OR are set up to remove +12V from the headunits ACC switched power pin, upon vehicle shutdown.

RCD310 power/CANbus inputs

9 – CAN bus, high

10 – CAN bus, low

11 – Display voltage supply, positive

12 – Voltage supply, negative, terminal 31

13 – Display HV CAN bus low

14 – Display HV CAN bus high

15 – Voltage supply, positive, terminal 30

16 – Anti-theft coding control signal, SAFE, positive
[Android Head-Units] Dream Reality Syndrome:

This is the one i have and love it now the mcu issue has been sorted!
[Android Head-Units] kaween:
Nope. That's a Telechips design. The facia/frontplate is similar to ZexGx's Zhoon device, but that's where the similarities end. If you want an AN21-like device, look at the second link I posted for Ackms421. The AN21's/TH designs do not have a "flawless" image, but the Telechips designs have an even worse reputation ...

[MENTION=4521853]Journeyman91[/MENTION] : I was gobsmacked by 2 things on those pics.

1) that's no doubt the cleanest garage I've EVER seen. :cool:

2) It breaks my heart to see that dashboard cut (the bottom line .... looks terrible, and doesn't do justice to the rest of your work. You've got a far too nice car to leave it that way I think).

If I were you, I would think about searching a small, thin, flexible 90° degree angled plastic profile, bend it more so it becomes flush with that dashboard under the radio unit, find somebody who can "do" the color of your dashboard and insert that painted part between radio and dash to create a clean, straight cut. When done carefully, the result would look factory-like. If I had done my cutout like that, I would've driven my car in a tree or something because I'd be constantly looking at it ..... :)

Ernsthaft : Es sieht etwass ... najah, beschissen aus. und tut den rest deiner Schöne Arbeit nur Unrecht. :(

As asked before please can someone host 2.8.3 as it is not available no more and the one i have fails.
[Android Head-Units] MFKinSINY:
I downloaded it last week. its on a usb stick at home & I am at work. I might not have a chance until tomorrow to upload it to my dropbox. when i do, i will post the link. but it seems that a few firmware versions have been removed. maybe you really dont want to mess with 2.8.3
[Android Head-Units] Skratchuk:
That will be good thanks, i heard a few people thought the 2.8.3 was good so thought i would try it.

Hey, I see that there's a "specific" 1024x600 system. Aren't all compatible? My unit has that resolution.
[Android Head-Units] Journeyman91:
Hi fellow countryman,

1) SADLY it is not my garage - it's the garage of the guy car wrapping my bella converting her from silver metallic to dark red brown matt. The brownish part does just appear on lower light though =)

2) I know, right! I was just so exhausted of this whole cutting jigsaw stuff inside the car to make enough space for this big ass radio unit (since the car does not have a native DIN 2 slot available) that I lost patience while cutting the dashboard... In the end a really stupid move. I am actually thinking about rasping erything down to a straight border and than let the car wrapping guy wrap it again for the optimal looks. Would cost some time and another 50 bucks thougt. Let's see.

[Android Head-Units] gyaku_setsu:
You are correct. As a VW owner, I have a TON of experience hacking in to the CAN network to add devices. The signal from the can network is what turns the radio on and off. A CAN decoder box of some sort is required to make any aftermarket head unit work. The one they provide optionally with these units is probably the best bet and provides the acc turn-on wire plus steering wheel control functionality.

Does anyone know if this (or any) update is compatible on a system that does NOT have a DVD disc drive? If it is compatible, would it add a useless app for disc playback, or is that dependent on it physically being there?
[Android Head-Units] SwiftStorm:
Thanks, whoever posted 2.8.3 up along with the rooting tool! Amazingly, my unit boots up a lot quicker now versus 2.7.30 something.

Also, to the guy with the screen fadeout problem, it definitely is something to do with lack of power, since plugging in my phone to charge immediately after cranking the engine causes the problem 100% of the time, whereas waiting for a couple of minutes doesn't cause the issue, so it seems like the power needs to stabilize first.
[Android Head-Units] Dream Reality Syndrome:
So what unit is the preferred one ultimately, of all these android head units? I'm having difficulty trying to decide which to pull the trigger on! I hear of the problems with the Hui-Fei units, but don't know much else about any others

If I were to go by mere specs, I would think that the Telechips were better due to the multi core higher speed processors.

Idk in the end I want a universal double din with a decent processor speed, no DVD (for a hopeful 7" screen), US digital TV, WiFi and 3g at the same time, possible obd Bluetooth capability (already got my Bluetooth adapter, but I'll probly purchase the new WiFi instead) iPod and HDD capabilities

From what I understood from the translation, they might have removed all firmwares with the "Unauthorized UI" red warning messages because they are not legit or haven't come directly from the manufacturer. But this is just a guess.
[Android Head-Units] kaween:
Good question. Ultimatly, I can't tell.

I however do know the SNAC-7005/8009 like devices (Szion is the manufacturer of them I think) have build themselves a very iffy image by not delivering what they promised. For example, one seller told me the first batch they received was unusable because of stability issues, the second batch suddenly had different cpu specs and the third had only half of the advertised memory size (8gig instead of 16) and stated cpu speeds that are not real (quoting 1.7, but only running at 800 mhz !)

Another thread about these Telechips started out with these devices promoted with an Exynox cpu which was afterward downgraded to a Telechips without letting the customers know (WD 8801) .... and that thread is a graveyard where android dreams come to die so it would seem.

I'm not telling saying the AN design is brilliant or flawless because it certainly isn't. My own unit did fail (see thread) and I had to repair it. But if I look at the list issues with the Huifei's that seem to grow and grow (I considered a Huifei myself after my AN21 died, only to see the thread go from "Whohoo" to "Booh" in no time , or the crap the customers of the WD8801 had to go through, I don't think going with the TH/AN design is the worst choice you can make.

But that's just my personal opinion.

[Android Head-Units] Zaphod-Beeblebrox:
I concur. I have both the Ouko 6.2" (single core, resistive screen, android 2.3) and an AN-21. I looked very hard at the HuiFei and WD8801 units before buying the AN21.

Even though the AN21 has many many faults, it does seem to be the most stable. I'm quite happy with mine. I also don't do a lot of version trying/upgrading. I think I'm on 2.7.28 or something, and it works perfectly fine.

As any self respecting geek, however, I'm always looking for 'The Next Big Thing' (and, no, I don't really care for Samsung :)). Found this:

[Android Head-Units] Miwer:
I'm a VAG owner too, and just starting to mess with the CAN bus. I have some bugs with the CAN bus adapter that I want to sort out, and maybe build my own adapter, but it requires a lot of knowledge about the CAN bus (and also the messages sent between the head unit and the adapter). I have started out with some basic signal line and logic analyzer measurements, but I'm just getting started, and I need to analyze a lot more before even attempting to make my own adapter. :)

Can you suggest any software tools that are good for CAN bus monitoring/statistics, and perhaps translating the bus messages into something meaningful? Or maybe you have a "cheat sheet" with the different IDs and values, that you can share? Feel free to pm me if needed :)
