Update : one striking advantage of Tomtom compared to Igo : the voice guidance in my native language (Dutch) is 100% better than Igo's. Not only is it far more concice, it's clearer, far more logical (in terms of grammer) and has no issues with the correct pronounciation of street names. Igo's voice guidance is iffy it at best compared to it, leading to several "WTF ?" moments when driving.

Granted, Igo looks far nicer. The map engine in both Sygic and Igo make Tomtom's display look a bit like Win95 Gui compared to Win7 Aero. Tomtom really hasn't aged well. But most of the times, I use the voice guidance, not the display of my GPS systems to navigate so I don't really care. On my previous car, the navigation system consisted of only a voice guidance and a very rudimentary "arrow" system (RNS system by Blaupunkt).

The fact Igo still has that TMC-like part -which really works very well !- still can push me over to the Igo side, but for now I'm definitly going to test Tomtom on the AN21 in a very rigorus manner.

I know Igo can cope with TT's maps. But even then : on the same hardware, I've seen Igo thinking I was doing 120km/h on a dirt track that ran parallel to the highway due to Igo's iffy "stick to road" GPS system. This issue isn't new : I've seen Igo struggling with this since the very first versions of Igo that I ran on a Mitac 168 Wince PDA .... a long time ago. We're years later, and Igo STILL does stuff like that. TT never did such odd things.

Let's see how the verdict is after a couple of days of testing. Will report.

well I had all 4 install tomtom, sygic, igo and garmin instal and I play with all 4 with the process of eliminations . Garmin was to go 1st then tomtom. I still have sygic and igo install on my head unit. I love sygic ease of use when traveling through small towns. and the fact that sygic show you speed change coming toward you when your driving and prompt you of the change in speed.

I am still reviewing both right now

Now the beauty of IGO the voice prompts I can set igo to announce 1min up on alerts.

*red lights camera ahead

*the speed limit is 40mph please slow down

*toll boot ahead prize $1.50

*warning HOV lanes ahead

* speed increase to 40mph

*it say stop at every stop sign which is very annoying I can turn it off but the chick like it lo

*at school zone children in the area

* you have 2hrs left on your destination

* the fact that you can set driver time to drive

IGO is nice and I just got all the 2014 maps and poi another beauty I can use tomtom maps. I like sygic more but I can't get to edit the sygic poi and red light cams. in IGO all you need to do is go in Google maps and look up the intersections

X,Y,TYPE,SPEED,DIRTYPE,DIRECTION

-81.577502,30.352016,3,0,0,0

just add ur own lat and long of places of known red lights cam or speed traps and you made you own red light cam location for igo primo

How Do you completely Wipe the device as if new?

Hi there

How do you do a complete firmware overwrite of this unit. I am getting some weird behaviour and want to completely start again.

I have applied the full format... but me thinks this is not completely doing that.

Thanks
[Android Head-Units] ryrager:
Ok done what I think I needed to but I am missing the Boot Logo App and not sure how I get it back?

Animation or logo ? Logo is in settings.

Is the debug password a feature coded into Android itself as a safeguard, or something that's custom coded (or even hardcoded) by the manufacturer or firmware developer? I can't find any official documentation in the Android developer's site that could mention an USB debug password feature.
[Android Head-Units] sciallo:
Ok, so, does it still ask for it if you try to enable it with an app like https://play.google.com/store/apps/details?id=me.tennkia.apr&hl=en
[Android Head-Units] bmj67:
The password is set by the manufacturer.

Yes it still asks for the password with that app. All that app does is provide a shortcut to the developer settings page.
[Android Head-Units] sciallo:
Bummer, well, that would have been too easy... was worth a try :)

Do you guys remember this video?

http://www.youtube.com/watch?v=HHffZq1WPwU

A salesman from RoadRover contacted me through Facebook, and he told me they're working on this new headunit and they're on testing phase, looking forward to release it by the end of 2013. I also told him about our interest in improving the unit by rooting it, which will greatly benefit both of us: our community and his company, hoping they'll release it already rooted, or make things easier for us to root their unit.

Let's see how well it goes. However I'll continue my research on the headunit we already have, and post any results I could come with.

UPDATE: He told me to email his technician. If you have any good questions, or arguments to convince them, feel free to post so I pass them to him.
[Android Head-Units] bmj67:
Looks like the hardware specs are almost the same. They may even start with the same base software. Maybe ask the tech if they have a usb debugging password. If so what it is.

Questions About Features

I want to know about the following things:

Google Now - Does the unit support it? Voice Commands?

GEL - Is it possible to install this new launcher and have google now available from the launcher like in the new kitkat N5? (see link below)

http://xdaforums.com/showthread.php?t=2529594

The phone app is just glorified bluetooth for your phone right? For example texting is probably not supported through the unit... WHAT ABOUT HANGOUTS?

I know the unit is said to have 8GB of on board memory, but that really its only 1GB for apps and the 8GB is seen as USB storage (correct me if i am wrong) How would an app like google music function when it caches music or I pin a playlist to be physically stored on the unit. Could I choose to have the music pinned to a 32GB sd card for example...

Can apps also be installed to an SD card? I plan on installing a GPS app with all maps for US, would I install it to the 1GB memory, 8GB USB memory or an external SD card. Is the map data separate formt eh actual app install?

How about quick settings and notifications pull down. I havent seen it demonstrated... Is that functionality there?

I just want to get some more info on overall features before taking the plunge or beginning to think about modding it.

Thanks
[Android Head-Units] KID52:
Maybe, but they do not even offer the features we want.

Did you post on my YouTube video? I mentioned there I would be interested to know also, and if you know a cheap one to purchase I will get one.

Seems good, but I do not use it very much. My car is known for bad radio reception, doesn't even have external antenna, I have no idea where it is.

Where did you find this information?

There is a limit as to how good radio reception can be anyway. I have not had any problems with my car and radio reception, but then again I didn't buy an expensive Android unit to listen to the radio...

Yes, Peter Chan is just a very small reseller.

I believe the manufacturer to be "RoadMaster", or at least, they make an identical unit, however since pestering them for update files, debug password, etc, they have ignored me completely :(

First they agreed to tell me the password after much discussion if I signed a disclosure agreement, however the next day things had clearly changed because they refused and then stopped talking to me.

I have tried new accounts, but they all get ignored and I am met with generic replies along the lines of "we did not sell you a unit, contact your reseller".

Maybe if other people harass them they may crack?

http://www.aliexpress.com/item/Car-...pacitive-Screen-Supports-WIFI/1357172698.html

Peter Chan tells me the actual manufacturer of the unit is "Tonghai".
[Android Head-Units] bmj67:
I got mine direct from roadmaster. They have stopped responding to my email as well. Before they stopped responding they said they were working on the obd2 and that they were showing a demo unit at some tech fair.

I can't get sygic to work right and need to delete all files and reinstall. But they are system files and I can't delete. I will continue to try email.
[Android Head-Units] KID52:
They aren't working on OBD II in the way we want it though. I posted in the news section of the first post what they told me, which I assume is the same as they told you.

They are not allowing us to use Bluetooth to connect to OBD devices, they are working on their own hardware and software so they can charge even more, I was told $50, for something that would cost us at most, $10 for a dongle and OBD device.
[Android Head-Units] donaldta:
?

Is it possible to upload a copy of the /system/framework/framework-res.apk and the /system/app/Setting* files from the running system? Maybe we can ascertain more information from it by decompiling them.

Yes I posted also on your youtube channel, it seemed you where unavailable there so asked here again about the radio reception.

If you can confirm it is ok like other radios it is good, of course you don't buy such device to just listen to FM but. But in the end it should also have some basic features. I ordered once a cool android iphone-clone from china and it was really stunning how it looked like, but it was really useless because the call quality and reception was so bad. So I sold it again.

Radio is for me really important in car to get trafic updates and news on the go. So it should work like it is supposed to. Its a basic feature so should be too coplicate to realise but it seemed in the past taht they often have problems to get it right when it comes to grounding, shielding, antenna connection. There are many threads in the china-rns.com board about the bad FM reception of chinese Car Stereos.

Anyway I orded one device to test, I asked about ODB and Peter Chan told me it needs 1 week to produce at most 2 weeks so I hope and can give you update about this.

Actually the ODB interface looked really cool on the screenshots, It is with Fault Code Description and can also read live data like speed etc...

He told me that they add some thing on the device + the ODB Dongle so I guess they add a secondary bluetooth. So I think it is ok to pay 50USD for the support if it works well.

Once I get my device I can tell you more.

About the connection with the manufacturer, my company order much from china and is this way.

If you tell the manufactuer you have bought from a reseller they won't talk to you anymore. They don't care about you. They don't want to loose the reseller as client. You have to be client directly at the manufactuer otherwise they don't provide information. You need to buy samples from them and don't tell them you have already devices. After opening the honeypot you get what you want because they want to sell more.
[Android Head-Units] Orisai:
Yes, there's a company named Shenzhen TongHai Create Technology Co.,LTD, which makes car stereos, probably cloned devices for others to put their brands on.

I tried wireless adb but cannot connect because I can't change tcp port. Also I can't find framework apk or settings files. They hide them somehow and file managers won't show them even with show hidden siles option checked.
[Android Head-Units] slinkydonkey:
Do any of these devices support DAB?
[Android Head-Units] patrickoneal:
I don't think it's been asked, but, does this look like the same stereo?

http://www.ebay.com/itm/Android-4-1...Video_In_Dash_Units_w_GPS&hash=item4acc610bbb

At $329, it seems to be a much better deal than the $509 model you posted. It claims to be capacitive multitouch.

The only difference I could find is that the cheaper unit claims to run a Dual Core A9 at 1.2 ghz(it says 1ghz elsewhere) compared to 1 ghz for the more expensive unit. The cheaper unit also doesn't include a TV tuner, which wouldn't work in the US anyway.

Also, has anyone run Waze on one of these units? How's the GPS? Quick lock? Accuracy?

Thanks.
[Android Head-Units] KID52:
There appears to be an additional $85 shipping fee to the UK, not sure where you live. Still a good deal.

The unit does seem to be the same, less the TV tuner, which is pretty much useless anywhere to be honest. I am interested to know if it really comes with a 1.2GHz CPU or not though.
[Android Head-Units] KID52:
Not that I know of, however there does seem to be SDR applications for Android, that may work on this if you have a compatible USB tuner.

Screen unresponsive

Here is what is happening anytime that I turn the car on right after (est 2-3 mins) turning it off. The screen is unresponsive and I have to pull the battery in order to drain the head unit. Is anyone else having this issue?

http://youtu.be/lIa2rogtRXE
[Android Head-Units] donaldta:
Yep, you can see it is resistive looped. I highlighted in red boxes where your M11-B connector is and showing the relevance of wire #'s 4 and 17.

Don't mind the clock spring. All that is, is a ribbon cable that is wound up in a circle so that when you turn the steering wheel it loosen / tightens but doesn't break as if it was a straight wire. But, if you follow the circuit you see all the switches which kind of looks like doors and the resistors that looks like a bunch of \/\/\/\/ in a line and the circuit loops back.

In this drawing the radio is supplying voltage on #4 which thens gets reduce from the resistors depending on which switch is depressed and then flows to ground back to #17.
[Android Head-Units] omarko:
awesome and thank you again ...

so now that we know its resistive, how am I connecting it to the radio ?

wire 4 from the car harness to Key 1? Do I need to connect car wire 17 to anything ? Ground? or Key 2 on the Radio ? Im sorry im bit slow with this!
[Android Head-Units] donaldta:
Wire 4 goes to Key 1 and Wire 17 would go to Ground.

Remember, you would only use Key 2 if your buttons were physically separate by two circuits as written in the example of my last post. For example, the Play and Pause buttons are represented on one wire but Rewind and Fast Forward is on the other. Since all of your SWC buttons are in-line in a single circuit you only need to use Key 1.

If it helps think of Key 1 as Multimeter #1 and Key 2 as Multimeter #2. You only need to use the second multimeter to measure a separate circuit.
[Android Head-Units] sorin129:
Thanks for that. I did find pin A1 on my car harness but now I don't know which wire I should connect from the radio. I assume that Key 1 and Key 2 are out of the question because they are analog and from what you said about my car is digital. So should I connect CAN tx wire or CAN rx wire?
[Android Head-Units] donaldta:
I'm afraid that I do not know the answer to that question. I normally see single wire Can Bus signaling where there is CAN+ (Can Bus High Speed) and CAN- (Can Bus Low Speed). In most cases, when there are two separate wires, they are separate low speed and high speed buses which carry different information. I'm not particularly used to seeing a separate receive and transmit. Which is where the wiring for the AN 21-U confuses me a little with the Can TX and Can RX. Because this suggest that the bus is divided by transmit and receive like a telephone. I would guess maybe RX since you want to receive signal from the ECU. Or maybe there's meant to be a separate module for it? Probably the best thing to do is ask the dealer about how you're supposed to connect it to a single wire Can Bus High from your car.
[Android Head-Units] sorin129:
You are probably right I need something to connect the 2 wires from the radio (CAN RX and CAN TX) to the one wire (A1 pin) from the radio harness but I'm lost and don't know what i need and how to get it :(

Edit: I did try to just connect the Can Rx wire to the can bus wire from my car but it does not work
[Android Head-Units] donaldta:
It wouldn't hurt to ask the seller. If they can't provide information or options. Maybe try to find the schematics for your car's steering wheel controls. Ironically, most cars still use analog circuitry in the steering wheel column before being fed into an ECU and turned into digital signal. I've done this on cars whose digital connection isn't supported by the current SWC adapters. If you can figure out which wires to intercept then you can wire it from the steering wheel column instead of behind the radio.

If you do that and you need more than two wires, maybe consider using a CarPc JoyconEX which would convert your SWC controls into USB HID Key Events. One of the downfall of the AN-21 is that the internal SWC offers limited controls to particular applications. Using this adapter would make your SWC controls more universal since it would be represented like a USB Keyboard.
[Android Head-Units] sorin129:
Thanks for all your help. I guess I'm going to try to intercept from the steering wheel column. I assume that if I do that than I would only need the Key 1 and Key 2 wires from the radio and not the CAN rx an Can tx. Thanks again from all your help
[Android Head-Units] typos1:
Bogo MIPs is just to get a rough idea of processor speeds on devices running Linux, its probably adding together both cores to get that figure.

Most dongles come with their own DVB-T app, there hasnt been a generic DVB-T app in the Play store over the last year or so. I ve been checking, as currently I have a Chinese Android 4.0 TV box with a DVB-T tuner rigged up to my OEM built in sat nav, using a video-in box and the standard DVB-T app lacked the features I wanted. I ve not checked for a few months, did before I posted and there is now one generic app for a few tuners, but it had very poor reviews. Happy to extract the APKs from mine if anyone with the DVB-T version or a dongle wants to try them, have a feeling it wont work though - have had 2 slightly different Android DVB-T boxes using exactly the same board and I swapped the apps round and neither worked, even though the board and Android version was the same.

KID52, I take it you realise just sticking a DVB-T app on wont give it DVB-T ? . . . unless youre thinking its there but has just been disabled on non TV versions ?

I m not sure what my usb to OBD2 lead is, I m sure its ELM327 compatible but unsure if its FTDI, I ll have to take it apart and see, it has had 2 of the pins bridged so it can be used to access ABS and airbag ECUs though, I ve had it for about 5 years. Tried using it with Torque on my Galaxy S2 (knowing it wouldnt work cos its GB, but tried it anyway), a cheapy Chinese tablet running ICS and a Newman N2 running ICS, the last 2 did not have usb OTG, so thats probably why neither worked, if I get donaldta right and hopefully my obd lead is in actual fact ok. Wont bother trying it with my Oppo either as that lacks usb OTG :(

Anyone tried benchmarking with Antutu ? Seems to be the most widely used benchmarking app.

And can anyone confirm they come with 4 RCA outs, as some seem to only have 2. Also, anyone with a unit know what the voltage level is from the pre-outs, 2V, 4V 6V etc ?

Which key layout did they send you ? There seems to be several different key layouts, some of them with wonky labelling :mad:

Right, spent hours and hours reading this thread, been looking at getting an Android headunit for the last year and these are finally a decent spec, but theres so much info in this thread, my head is spinning, need a rest ! :eek:
[Android Head-Units] donaldta:
The easiest way to tell which USB to Serial adapter is in your USB ODB2 cable is to connect it to your computer. If you have Windows then check the Device Manager for the USB Serial Port that is present/disappears when you plug it in then remove it. If you have Linux then type "dmesg" at the a console prompt after a seconds of plugging it in. I don't remember how to do on Mac but I suspect you can also use dmesg since the underlying OS is based on Unix but I'm sure that it also has a GUI tool to check.

But, you're probably right that you'd have to take it a part to know for sure if its a Chinese clone. Because it may not even be a real FTDI, Prolific (PLF203) or Silicon Labs (CL203x) UART adapter. The funny part is that there are so many of these clones that the official drivers might not work. Prolific, for example, have devised a method to detect the clones chips in their drivers and refuse to work them. So, often if you have a cloned UART adapter, you have to look for old drivers or get spoofed drivers from the dealer.
[Android Head-Units] jakejm79:
I believe there are certain versions of the AN21-U (i.e. for the VW) that allow changing/broadcasting data to the HUD or Climate Controls from the headunit so that is what the transmit would be for, i.e. the VW HUD should allow for displaying the current radio station, etc.
