Polarlander 7080b firmware update help.. new to this whole mcu thing. - Android Head-Units

So I've been looking for an updated version of this mcu6905:V12.22 software/firmware. The eBay seller sent me the I guess original firmware. The product info tab/button says this.
soft version:V7.3-6905BT-TP
Info: MP5QQC70PW1011F01M6905
MCU6905:V12.22
CMLPLAY ver:CMLPLAY 8.0
date:2018/12/13 17:38:19
The inside of unit says that the board is a 7018KB.
I'm not sure what it's capable of doing at all. I'm pretty tech savvy but new to firmware like this and how to tell what I use or reference for this model. Any help to ease the confusion of how to update my device or even mod it. I am really wanting/needing subwoofer control. And possibly anything cooler then this bland ass layout. Thank you. I'll add pictures as well.

Sony xav-601bt - Android based headunit with MirrorLink

For those of you who don't know about these new head units. It is the first headunit that is running an Android based operating system that is compatible with MirrorLink.
I can't post a link but if you google "mobile electronics magizine xav-601bt" you can find a lot of info on it.
I am curious what people are going to do with these once it is rooted, just think of the possibilities!
What are the chances we can get MirrorLink to work on all android based devices? So far it looks to only be planned for new phones but I am sure that we could change that.
Nobody else thinks this is amazing? You now can install an android based computer/audio/video in your car that you can mirror your phone's interface on!! Literally your car can now do everything your phone does, something people have wanted to do years.
I'm doing some research on the XAV-601BT right now. Saw you posted some info on another car audio site and I would like to know what you think of the unit. Such as: what apps would currently integrate an xperia pro freshly updated to android 4.** and are there any known issues with particular devices or configurations? Any mod sites messing around with getting rid of the bugs yet, safety nannies or performance wise? I can't find much besides chatter yet.
You mentioned that you had access to a unit and if it is installed could you give some details of what it is pushing and how it is performing?
Thanks allot. I am holding out for another unit that has been delayed again but this might make me pull the trigger. And yes, the prospect of running all my phone apps via my head unit makes me happy, let alone being able to root and customize.

I think you don't have the right phone for it.. only Nokia and the new Samsung Galaxy S3 support Mirror Link.
I've read somewhere that Mirror Link is hardware based, but maybe it's the same technology as MHL.
Thanks for the reply. I read that the 2012 Xperias would be MirrorLink capable too. I came across conflicting information on it being implementable for smartphones that had output capabilities of uUSB and HDMI like my Xperia pro. If a phone can support RealVNP I think it should work but I'm just learning about this technology. I've got some research to do on this before I pull the trigger because I want/need qwerty with my hand size and I don't see anything similar to the pro in the pipeline that would come factory capable with MirrorLink.
Anybody know for sure what it would take to run MirrorLink on a phone like the 2011 Xperia pro?

He is right about the S3 and nokia phones being the first supported. Windows phones and other phones are expected in the future but there is little information available. I originally heard that mirrorlink was a hardware solution but now I believe it is software. There is a good chance that it could be ported but it is going to be hard to tell until the S3 launches and some people on here start playing with it. I also hope they make an area for the XAV-601BT and XAV-701HD on this site so people can start focusing on rooting the unit as it is Android bassed.
I have used the unit and even without the mirrorlink it is an amazing unit. It literally does everything I could want in a double din head unit.
I currently have the xav-601bt i picked up from my audio shop yesterday. I also have a htc sense and the unit will only display unsuported device. Speaking with the sony west coast rep today, I was informed that there will be rollouts for the mirror link. It seems that it will be an app you can download from the play store.
The rollouts are expected to be every 60 days, but as for what phones are capable of running the mirror link protocol remains a mystery.
I offered my phone to be tested for there software but he will have to check with his higher ups about that. I am hoping that it will soon be available for download and one of the developers that crack it to work with other phones, like the netflix and hulu apps.
I am still waiting on information from the east coast rep on this as well. If I get anymore information I'll be sure to post it here.
Could you post some experiences with this unit? Do you think it's fast enough? How about the touchscreen; how well does it react to your finger and what about the sun.
There is a russian video on youtube giving a demo of this device.. not much to understand (at least for me) but at least you can see the features a little bit:
http://www.youtube.com/watch?v=rGMxaMnfTFo
http://www.youtube.com/watch?v=YB9V641jTZQ
As you can see in the video, it's not as smooth as I hoped for.. sometimes you have to touch something two or three times before it works.

I have this unit as well and have had it since late May. It is actually pretty responsive(for a touchscreen head unit) and boots up fast. I am coming from a x930BT which was horrible in both of these areas. The having to press more than once is more related to how accurate you need to be to hit what the unit considers the button. It is small area that accepts the input for that button, hopefully they address this in a FW update.
As for the Sun question - pretty bad, but my car has a bad location for the radio that doesn't help the problem any. The sun beats directly on the screen and it is completely washed out.
Thanks tvrvic for the reply
Hmm the sun problem is not a good thing, a lot of units have problems with that and I hoped that a big company as Sony wouldn't have this problem.
I've had this unit for a few days so far and love it. I'm order the steering wheel control adapter today. It has a matte finish on the screen and that helps the glare, I can see the screen just fine.
.
Thread moved to Q&A due to it being a question. Would advise you to read forum rules and post in correct section.
Failure to comply with forum rules will result in an infraction and/or ban depending on severity of rule break.

Thanks, I also just saw this link: http://forums.mcx7.com/showthread.php/132693-Double-Din-Sony-XAV-601BT-Install-pics! with a photo of the unit in the sun and it looks good
Now we just need to root it
Hi Guys just asking for a bit of an update - im in the uk so the bigger 701hd isnt out yet, i was looking at the Alpine ICS x-8 which also supports mirror link - there is a demo out on youtube which shows it working with the Galaxy S2! Do you guys think this would work with the S3?

This head unit does not actually run Android, so there's nothing to root. It uses MirrorLink to mirror your phone's display on the head unit. You'll have to wait a few months for Clarion's double din Android head unit to release to have Android running natively on your head unit. There are some cheap no-name head units out there right now running Android, but they're poor quality and I don't think any of them are even running Gingerbread.
thanks for that info.
so the sony won't be hackable. given that, is mirrorlink's app approval mechanism hackable on the android end? does anyone know mirrorlink tech beyond:
Universal Plug and Play (UPnP™) is used for controlled access to applications. Virtual Network Computing (VNC™) is used to replicate the phone's display on the navigation screen and communicate user inputs back to the phone. Besides Bluetooth™, audio can also be streamed using the Real-Time Protocol (RTP).
MirrorLink™ also provides a mechanism that ensures only approved applications are accessible while driving.

I just installed this unit in my car - the Open source license page on the unit shows a lot of .apk files and also reference AOSP, and Linux 2.6.x licenses - so it is Linux
The mirror link support looks like it comes from tmlibs.so - which they published on their support site (Trying to find the links - I downloaded what they published for opensource -
the libraries they put on their site were: (Repeating tar.bz2 was their names)
EDIT: the url for the sony site is : http://www.sony.net/Products/Linux/Audio/XAV-701BT.html
GPL_SGX_KM_20111130.tar.bz2.tar.bz2.tar.bz2
alsa-lib.tar.gz
dnsmasq.tar.gz
iproute2.tar.gz
iptables.tar.gz
webkit.tar.gz
kernel.tar.gz
and the most interesting
ML_Necessitas_Build.tar.bz2.tar.bz2.tar.bz2
TmLibs.tar.bz2.tar.bz2.tar.bz2
The TmLibs looks like it has a mirrorlink server and client embeded, using the QT libraries in the ML_Necessitas, and there is an ortpLib directory in there as well.
Would it be possible they are running some android apks within the system as the USB music app seems very androidish (menus & icons) while the ipod app not so much?
http://www3.jvckenwood.com/english/car/mirrorlink/compatibility/kw-nsx1.html
Support for the Samsung GALAXY S III is planned. Car Mode compatibility will differ by country or region.
Support for Europe was going to be available on July 20 2012.
But, Support for Europe will be delayed to August 31 2012, because of software development has been delayed.
And timing for US/Canada is TBA. Support for Asia/Middle East is TBA.

So MirrorLink with the JVC will work at the end of August, so I guess that will also mean Sony will support it by that date.

It's an RK3188/1024x600 unit made by Klyde. Don't expect any free "support" from here on any of the units, but the firmware and extensions found here should work as well on it as on any other model. The majority of these Chinese units are based on the same basic design, just repackaged with different cosmetics.

As in support i didnt mean like it that way, was referring to firmware, extension n them
so its safe to say that if i get the 1024x600 most of the stuff from this thread should work http://forum.xda-developers.com/showthread.php?t=2660662
Thanks for confirming that for me, ur a champ mike.s
Anyone ended up getting this unit?
How is the sound quality on it? Better or worse than OEM?
I have a 14 Passat with RDS310 - sounds was ok but not that great - then installed a Pioneer Appradio 3 - sounds got considerably better.
Then played with an Ouku Win8UI 2015 version, sound got degraded, probably to the levels of OEM or maybe even worse (to its defense, it has lots of options to play with EQ/Sound mode, but it still wasn't clear enough).
The Pumpkin quad code (KD-C0346) seems interesting, but I'd like to get a unit that is par with the likes of Pioneer (at least the AR3) sound wise.
Any thoughts?
thanks

Horrendous experience with Newsmy and Aliexpress

Starting this thread as a warning for everyone.
I bought a newsmy carpad 3 and the unit was bricked during an update. I contacted Newsmy for any help with the unit, and to my horror received absolutely no response to my request for repair. The unit does not have any hardware button combo to get into a boot loader mode, which I would put down as a design flaw - but the lack of any communication is stark of how Newsmy would like to treat its customers, is the real bummer.
I gave the seller a 5 star rating when the unit was delivered , now ali express says I cannot change the rating. The seller has no obligation to respond back, and can sell freely in the absence of a negative feedback and the money is gone too. Overall, a lost cause.
Would recommend caution when using a site like aliexpress or a seller like newsmy. Better go with another unit or seller. Anyone has any thoughts on what I could do next, do let me know.
Why did you update it? Any particular reason?
You know those units are put together from gazillion of different hardware bits, and only one difference is enough to brick it.
I'm sure that chinese don't stick to reference design at all costs.

My 3G dongle was not working, hence tried the update. I think a hardware combo for boot loader mode is a basic necessity. This is actually the first product I have found, which broke because of software. Never happened with any of my other devices, hence my crib of a design issue.

Yes, I see. I also dont like devices with capacitive buttons, that's the reason why.
But where did you get the update from ? Did they supply it in which case they should sort it out or did you source it yourself and assume it was the correct one for your unit ?

E39, PCD7739B, Xtrons, Root, Update, Chinese Headunit, Android

Good evening gents,
I hate being that guy on a new forum with one post asking for his hand to be held, but this is my first Android/Chinesium headunit and I'm unsure what to expect.
So I've bought a Xtrons PCD7739B that has been refurbished on eBay. Was over half the price, but has come fully packaged in a sealed bag with the screen protector still on it, so it seems basically brand new.
First impressions are good. I can't plug my S7 Edge in and use the head unit to access files on it - the phone complains that there's something wrong. Bluetooth works good and I can use screen mirroring.
I'll finish rigging it up at the weekend, but at this stage I'm trying to understand what I can do with it. The operating system that's on it does work fine, it just seems a bit "Chinese".
I'm trying to find in lay-man's terms why rooting would be good, if I can root it or what other apps/things could I do to improve it. Functionality, it seems to be good and from what I've read - it's like rooting means you can sometimes lose some functionality due to software bugs.
I've checked out the System section and there's:
Android Version: 7.1.1
MCU Version: T5.3.19-36-10-E53201-171204
System Version: V8.3.2_20180716.143957_MLT4-DVD
DVD Version: 2.13.15-860mc-150417
I've searched for T5.3.19 and I'm not finding much, so I'd rather not just do my usual and go ram-stamming in and understand what I'm doing, why, and if it's the right thing.
So TL;DR:
I have a PCD7739B
The OS is fine but could be nicer
Is rooting necessary?
Are there other apps that would make it better?
What rooting options are there/does anyone have links to ROMs?
I appreciate any help you guys can offer.
Cheers,
Adam.
So I emailed Xtrons on the same night I posted this and they got back to me saying that they haven't updated the firmware for this model in quite some time and that it is not suitable for rooting.
Not sure how much I believe of the second part but meh.

Update Android Chinese Head Unit (822L YT9216C)

Hello, and thaks for wellcome me to this forum!
Since I'm new here, I hope that I posted this to the right place...
Anyways, as the image says, I have purchesed a month ago this chinese head-unit (Car Vision, model no. DD-A01), and I have noticed that it has a very old version of android! On settings says that is 8.1, but... I have used a software to check if that is true and I have learned that is Marshmellow... obviously I want to update it, and since the update button is deactivated, it means that I need a specific ROM, and I don't know how to do this, or where to download it from. I appreciate any help from you, because even this head unit is a budget one, I don't want to brick it...
Thank you!

Welcome to the forum!
So first of all, you're absolutely right - you currently have Android 6 (API 23). The latest supported firmware is Android 8 (API 27). The process of changing to Android 8 can be quite complex for a non-expert Android / PC user but it is very much possible.
To manage your expectations, you will probably not notice any difference between 6 and 8 in terms of performance, user experience or sound quality. For this, you need to look into custom firmware that is nearly always a much better choice.
Although I don't have any software packages for your particular unit, feel free to browse the guides in my signature that will give you a better understanding of the process itself and benefits.
If you live close to London, UK and would want to loan me your head unit for a few days for development - PM me.
Thank you! I'm studying your guides right now!
So, is Android 8 the latest update... I can't wait to install it! But I want this to be done properly, so back to study!
