I am trying to download the latest version of Edition Firmware ST 0.9.9 Test. I believe it is a variation of RedMod but with some additional tweaks. I don't have 10+ posts on 4pda.ru so I cannot download it. Has anyone tried it?

Also, I have yet to install RedMod with fears that I might screw something up. My unit is slightly different than most that are on this forum. I also have a really nice setup on my unit right now and it took a lot of work to get everything just right. It looks a lot like a current Android device (I'll make a video soon). My only current issues are sometimes I will experience glitches that seem to be due to slowness... Sometimes my Waze app will not fully load and stay at a black screen, sometimes switching between apps takes a long time, sometimes my wifi wont connect (very rare), sometimes the unit just seems sluggish until I reboot it.

I would hope that RedMod's optimizations would make my experience a little smoother. I really don't care about the stock apps since I never use them (except for the Radio, sometimes). Can any of you who have had experience with RedMod let me know how drastic the changes are? Do you still experience similar bugs, lags, etc... Basically is it worth all the time it will take me to install it and set everything back up? I dont want to install it and realize it doesnt give me much benefit. I already have Root, Viper, Xposed, etc... So I am wondering what elese I might gain.

Thanks!

I installed a Eway EW842P radio unit in my car last year, which should be similar to the "AN-21 U".

Almost everything is working perfect, only problem is the GPS signal.

I used another GPS receiver as the receiver that was delivered with the radio unit (Link)

Navigation software is TomTom Europa

Sometimes I get really fast the GPS signal. Sometimes I need round about 5-10 minutes, until the signal is ready.

Does anyone know's that problem and has a solution?

Is there a possibility to use a GPS receiver which is connected on USB (maybe a UBlox Receiver on a USB FTDI connector)?
[Android Head-Units] dragoescu:
Hello,

I have an EwayGPS EW850P unit in my Ford Focus. The problem with GPS is fixed in RedMod firmware. You can try to backup the existing GPS configuration and edit GPS config files (http://www.xda-developers.com/gps-lock-faster-xdatv/).

You need root to do that. Make sure to rights to 644 to configuration file after replacement.
[Android Head-Units] Shadow128:
I think, the GPS fix has been done with the app GPS Status.

But I'll look into the gps.conf

Maybe not everything has been changed

Thanks for your help!
[Android Head-Units] Shadow128:
One more question to the GPS fix.

For correct GPS fix is a internet connection necessary? Or does this work only with gps connection?
[Android Head-Units] perieanuo:
that's not a gps receiver it's just the gps antenna with a shielded cable...your gps eeceiver is INSIDE your 'radio' unit.the speed for starting the gps module vary on those unit,cold start may be sometimes 2 mins.test with google maps or waze and report,the cracked sw mean nothing for diagnose :)
[Android Head-Units] dragoescu:
GPS works without an active internet connection.

GPS has an add-on feature called A-GPS (assisted GPS) which speeds up the startup (time to first fix). It warms up the receiver with GPS status data such as time, coarse location and most of all GPS satellite orbit location data. Everything of this is also included in the GPS signal but a cold start needs longer if the receiver needs to fetch it itself. With A-GPS this data is downloaded from the internet and fed to the receiver.

On my car navigation on a 48h not used car, after powering on the unit it take 30s-1min for the GPS to lock (without internet connection active). With internet connection active at boot it takes <30s. I have RedMod.

More info here: https://en.wikipedia.org/wiki/Assisted_GPS
[Android Head-Units] Shadow128:
OK, so I'll try to test it several times with a hotspot on my smartphone. So maybe with this it will be starting faster.

But does any tested it with an external GPS receiver? Maybe directly connected with a USB FTDI connector?

Or with a Bluetooth Stick and a BT GPS Receiver?
[Android Head-Units] dragoescu:
If I would need an external GPS receiver, after I purchased the unit especially to use it with Waze and GPS, I will burn the damn thing then run over it with a big truck. :D
[Android Head-Units] Edgaras7777:
Nobody have touchscreen.idc file for 1024x600 ????
[Android Head-Units] Shadow128:
If the external GPS receiver would work faster, then it would be no problem for me to use some external stuff :D

Anyone interested in a hardware mod to trigger system shutdown for pausing PowerAmp?

[Android Head-Units] Mancubus99:
Hey guys. Long time owner here. It's been a while since I visited this forum since my AN has been working flawlessly. I see a lot of talk about the RedMod. Is it worthwhile for someone like me who's not having any issues with his head unit to 'upgrade'? Also, do I need to wipe my data or will it get migrated?
[Android Head-Units] roystervi:
wifi Antenna

Hi anyone has a wifi card for their unit with a detachable wifi antenna ? I had one like this but it was not comparable with our unit.. Picture attach
[Android Head-Units] dragoescu:
Check the wiki. You will find there compatible wifi chipsets.
[Android Head-Units] roystervi:
I check the wiki already, I ordered one and my unit did not find it only the one that come with the head unit, the signal is a bit week.. now it comes down to experimenting, instead of me buy again and checking am asking if anyone has one.
[Android Head-Units] dragoescu:
I think RedMod has some new drivers installed, maybe it will recognize your dongle.

---------- Post added at 11:33 PM ---------- Previous post was at 11:31 PM ----------

...you can disassemble the original dongle and attach an antenna cable.

Which redmod firmware?

Can someone tell me which redmod firmware I should use, I mean there are two... One is labeled one button.. The other is labeled three buttons... What are the buttons? Mine has all sorts of buttons... Navi, back, menu, radio, etc. Any help is appreciated. Sorry if this has been covered.

TIA!
[Android Head-Units] roystervi:
Thanks I will look into that
[Android Head-Units] dragoescu:
Where did you found that information? I am using RedMod 0.2.5 and I don't know anything about one/three buttons...
[Android Head-Units] NMR2D2156:
__https://yadi.sk/d/TQi07P7qkFAP6/800x480/0.1.42

There are tons of versions but I saw 1.4 was listed as stable... Assumed thus link 1.42

Should I be using the 2.5 versions...
[Android Head-Units] dragoescu:
Use redmod 2.5: http://4pda.ru/forum/index.php?showtopic=641709&st=760#entry39934174
[Android Head-Units] NMR2D2156:
Thanks so much :) Wish I knew Russian language because there is so much information I could learn from on that site... Have a good day....
[Android Head-Units] NMR2D2156:
Ok. I installed redmod... I noticed there is no superuser installed to manage root access.. Is it OK to install supersu for this purpose?
[Android Head-Units] dragoescu:
I don't have superuser but i use root ony with es file explorer...and about Russian lng, you can use google translate for the website.
[Android Head-Units] Edgaras7777:
Hi, what root program you use? maybe baidu root 2001?
[Android Head-Units] dragoescu:
RedMod is rooted (su binary program is installed). You do not need anything else.
[Android Head-Units] patrickoneal:
Thanks for your reply.

I am in the United States, so it would ship free to me.

I've been watching the videos on youtube about this unit, I'm assuming they're yours.

Can you comment on the accuracy of the GPS and how fast it locks?

Does it always start the last audio app that was used?

I also wonder if all the units have the flickering/interference on the screen. Does yours do that only with the engine running, or all the time?
[Android Head-Units] KID52:
That is lucky, makes the unit very cheap, even cheaper than older models. I wonder why US gets free shipping, but to UK is $85.

I have put some videos up, so they may well be mine.

GPS is very accurate, and the lock is very fast even from cold boot. Put it this way, by the time I've opened up the GPS app, I have NEVER had to wait for GPS lock, it's always there. There used to be a GPS icon in the notification bar that would flash when searching, and be solid when locked, it would only flash for a few seconds, maybe 20 at the very worst case, before getting a lock. This was removed in the newer system update. I've never lost GPS signal, however I haven't driven through built up cities. My antenna is also in the dash rather than stuck to the window or similar.

Yes whatever DEFAULT application was last used, always opens on boot, even if you pause the music and close it. I have not found a way to stop this.

I haven't used any other units so I don't know about the flickering. No idea what causes it, it happened wherever I have had the unit, even sat in my room on my desk. Maybe I got unlucky. Best way to see it is to try install an APK file, that grey seems to set it off nicely.
[Android Head-Units] patrickoneal:
Thank you again for your response.

I pretty much only listen to FM radio, Pandora, and Audible audiobooks, so I suppose it won't be too annoying. The FM radio restarting doesn't bother me, as pretty much every radio does that.

How's the touchscreen? Is it comparable in sensitivity to a modern name brand tablet or smartphone? Have you tried it on a sunny day? I'm a bit curious if it's bright enough to be usable in the sun.

I'm sorry about all the questions. I've been looking for a native Android head unit for years, but the Chinese units have all been junk once you dig really dig into the reviews. Even mainstream units like the Parrot Asteroid Smart are half-baked. From your videos, this unit actually looks really well done.
[Android Head-Units] KID52:
The radio will start whilst booting, so be aware of that. Other apps start once the unit has booted.

Touchscreen feels very responsive and smooth. Cannot really tell much difference between it and my HTC One X.

Unsurprisingly, in direct sunlight you cannot see the screen, but I have yet to find a LCD device that you can. I've purchased a matte screen protector to see if it helps at all.

I agree, the hardware on this unit is good, and Android 4.1 is a big step up, plus now we have the Play Store which I think wasn't available as standard on the older units? In all honesty though, it is boring. The whole thing is locked down, leaving what seems like no room for true customization.
[Android Head-Units] patrickoneal:
Root would be nice. Hopefully it will come in the future. I know in the past, these Android head units have been discussed heavily on Russian forums, so perhaps there will be enough interest to get this thing rooted.

I drive a convertible, so brightness is a bit of a concern. I can see my LG G2 mounted to my dashboard in all but the sunniest days.

When the unit boots up, and the FM radio restarts, does the volume control work? It would be kind of annoying if you were blasting the radio, parked, and the next time you start the car you couldn't do anything about it for 18 seconds.
[Android Head-Units] KID52:
Hopefully a vulnerability will be found, As mentioned above, the unit is apparently susceptible to a root exploit, but we need USB Debugging and maybe more.

I don't really have much to compare the screen to, it was only parts of one journey recently that I experienced poor visibility as the sun was extremely low. As you can maybe see from the photo, the angle isn't that optimal either, kind of lends itself to being blocked out by sun.

Luckily yes, you can change the volume during boot.
[Android Head-Units] donaldta:
Yeah, that's because it doesn't have root. The third-party file explorers accomplish this by using the underlying Linux OS. Hmm... Do you have the ability to install terminal software, like Terminal Emulator? You might be able to use the underlying Linux OS to copy the respective files onto your SD Card.
[Android Head-Units] bmj67:
Terminal emulator installs fine. I was using it to try to change the port manually so adb wireless would work. I will have to see if I can find the source for setting and framework and copy that way. Hopefully they are not copy protected.

has anyone looked at these or is there a different thread someone could point me to, looks like the best deal to me just my opinion....I would love to see a review on these and know weather or not they support dual zones, ATSC, ect...I have seen these for under $400 us
[Android Head-Units] Maxael:
very cool!

I love the idea of a car stereo running on android! endless possibilities!
[Android Head-Units] patrickoneal:
I don't think you'll find one supporting ATSC. ATSC reception will not work in a moving vehicle. Other regions have mobile TV standards that are somewhat supported, but this is not the case in the United States.

I posted a link earlier in this thread to a stereo for $329 that looks to be the same as the OP has, except it doesn't have a TV tuner and supposedly runs at 1.2ghz rather than 1ghz. To me, that looks like the best deal.
[Android Head-Units] Flash473:
Thanks for the reply i found that same dual core model as above for $328 shipping and all, but has anyone tested one of these cant really find any reviews or anything. looks like it has the full market but again looks can be deceiving i have netflix and dish anywhere on my android devices that i currently own wasn't sure if they worked on these devices, and also if any of these units support dual zones....ie. kids watching netflix in the back while i have the radio and navigation going in the front...Any info would be great if anyone has tested any of this. Love the possibilities of these units :laugh:
[Android Head-Units] KID52:
If you mean the unit this thread is about, take a read of the first post.

Dual zone only works with a DVD, nothing else.
[Android Head-Units] sciallo:
I thought it worked with the aux in also, does it not?...

If it does, you could get plug your phone in with a n audio/video cable (if your phone has that as an option) to play whatever from your phone to the kids screen(s)

On another note:

Yet another android 4 unit... Kind of interesting, dual 1.5...

http://www.aliexpress.com/item/DH68...DVD-GPS-Universal-Built-in-4G/1299369913.html
[Android Head-Units] slinkydonkey:
Sorry for being thick but whats the differance between the PURE Android brand and this one ? http://www.aliexpress.com/store/pro...DVD-Player-Stereo-Radio/714323_754326240.html both are running Android 4.1 ?
[Android Head-Units] KID52:
I don't know, thought it was only DVD. The unit is back in my car now so I can't test it.

Few things put me off that unit without knowing more.

1. Only 512MB RAM.

2. Only 2.5GB storage for app data.

3. No mention of being pure Android or not.

4. GPS module seems to be of unknown origin.

5. Not sure if it works with USB hub.
[Android Head-Units] KID52:
Pure is not a brand (used in this context at least), it's a way to signify if the unit is purely running Android, or whether it has a Windows CE base system in addition to Android, the former being more desirable.

We think that one is pure Android and similar hardware as the unit this thread relates to, but as of yet no one can confirm this. The main difference is the i.MX535 processor. Which I thought only came in single core variant, but they are advertising it as a dual core.
[Android Head-Units] Flash473:
http://www.ebay.com/itm/Android-4-1..._Dash_Units_w_GPS&hash=item3a87ebd92b&vxp=mtr

this one here says it is 1GHZ dual core with 1GB ram and 8GB storage, as far as being pure android that was kinda in my original question because if it is you should be able to run all 4.1 apps unlike my google tv witch blocks certain apps from running...with that being said i may pull the trigger after the first of the year and test it out.....If someone does test one of these units out i would love to see a review of what works and what does not work as described... thanks agian guys very intersting topic :D
[Android Head-Units] KID52:
Looks to be the same as the one I commented on in post #77.
[Android Head-Units] Flash473:
My bad KID52 didn't see your post up there. but yes I believe they are the same
[Android Head-Units] sorin129:
Yeah when that happens ( it does't detect the head unit), as long as it detects the car ( from what I read you can tell you connected the right wire from the car by the green led flashes) than I can just manually set the head unit as Metra OE.

And as long as I got that dam Key 1 wire connected to the brown wire of the 3.5 female connector form the axxess (and of course plug the male connector in), than it should work.

---------- Post added at 10:16 PM ---------- Previous post was at 10:12 PM ----------

What would suck is if my head unit is defective and I'm going to have the same problem with programming the SWC even with the axxess adapter that I have now without it

---------- Post added at 10:28 PM ---------- Previous post was at 10:16 PM ----------

You are in the same boat as me. I tried for a week to get the unit to register correctly my SWC but it seams this head unit can't read voltages correctly. I had a lot of help from [MENTION=5389783]donaldta[/MENTION] but still could not get it to work. I gave up on it and ordered an Axxess ASWC-1 adapter.

Please let me know how you do with it. Maybe you have better luck with it than I had. Good luck :good:
[Android Head-Units] donaldta:
That can be easily tested without the ASWC-1 if you have spare resistor(s) handy. Connect one of the resistor to ground then start programming on the radio and select a function. To teach the resistance value then touch either Key-1 or Key-2 to the other end of the resistor. If you have multiple unique resistors then you can teach multiple functions. Then to test the programming just use the correct resistor between ground and Key wire.
[Android Head-Units] sorin129:
Very good idea but don't have any resistors and also, now since I already ordered the Axxess adapter, I will wait in till I get it and test it then. It would have been a good idea to do this before I ordered this adapter but I was so frustrated with it, that I just went online and ordered before you even had a chance to give me this idea lol
[Android Head-Units] gpmg762:
I believe what you need is a voltage divider from my reading of http://www.mp3car.com/fb-documentation-and-tutorials/117074-tutorial-steering-wheel-controls.html and solution C.

The headunit is definitely detecting signals from your swc from what you demonstrated in your video. I think the voltage is out of the range that the headunit can detect. The voltage divider (a couple of correct resistors) should be able to bring the voltage to the range that the headunit can detect.
[Android Head-Units] sorin129:
You are probably right but that is still the same conclusion I came to: that it won't work as is now.

So I ordered the Axxess ASWC-1 adapter. The voltage divider is probably cheaper than the Axxess but I would still need to know what voltages the head unit wants and how to connect it right.

I'm afraid it would be more complicated for me that the Axxess adapter. Ether way is clear that it needs something between the head unit and the car wire and it won't work just connecting the wire straight to the head unit.

Anyway after one week of trying to make to work I gave up lol
[Android Head-Units] gpmg762:
I understand the frustration of trying to make it work. I spent weeks trying to get the swc work with a previous android unit, erisin es777a and only managed to get 3 out of 6 buttons working.

This time I am much luckier. It all boils down to the unit we buy I guess.

Anyway, good lucky with the Axxess adapter, hopes it works well for you.
[Android Head-Units] ThePapabear:
I found an older connector for power cables for my old mondeo and it fitt´s to the new one also. So i did not have to wait until tomorrow and could make the test with my radio. Unfortunately the swc wont work...

I tested several things, they all did not work.

I have 6 models to choose (2x VW, 2x CRV, 2x Camry) and tried them all = changes nothing

I am very sure now, the issue is the radio, that does not add the necessary voltage.

- If i connect Key1 to pin 10, there are 3.23V and they stay stable. If i press any button, nothing changes.

- Connect Key1 to pin 11, there is no voltage as expected.

- connecting Key2 to pin 10, there is no voltage, also on pin 11

- found a cable on pin 9, which is not described on the plan, no voltage and no measurable ohms, but there has to be some resistance because giving Key1 to it, registrates the button. Same behaviour if i connect Key1 to any ground.

original radio

- Power On and Pin 10 has 4,75V

- Pin 11 nothing to measure

- Pin 9 nothing to measure

- pressing a button drops the voltage on pin 10 to a fixed one for each button; lowest was "volume down" with 1.09V

If the harness is not connected anyway, there is no voltage. Only if it is connected to the Headunit.

What brings the problem with "volume up stays":

- if you press start and select the key to set and keep the setting when, for example, connecting the cable to ground, the button keeps pressed for the radio, even if there is no more connection.

- Second way to get this problem is that you are in the menu, press start and select volume up to learn. Because it is not working, you hit "back" or "home" to leave the menu. So the button keeps activated and the volume goes up to the limit every time you start the radio.

In both cases, even turning the volume down on the wheel knob will not work.

I am sure now, i have to by something that translates the buttons from my mondeo to the radio. It would work without SWC, but if you are habitated to something like this, you will not give it up so easyli. ;)

Maybe someone can give me a hint for a tool that will work and i do not have to import from the USA or HongKong again, because i would like to put the radio into my car as soon as possible. :angel:
