Parrot RNB 6

Since the RNB6 project was cancelled, this thread is now closed.
Parrot RNB 6
The upcoming Parrot RNB 6 infotainment system (to be officially announced at CES 2015) looks like a promising device! In addition to the standard navigation and entertainment functionality we should expect from every devices of this kind, the Parrot RNB 6 will have some extra functionality which, in my opinion, will make it the best solution available on the market for 2015. ODB-2 Compatible with on screen car diagnosis, on-screen climate control and both CarPlay and Android Auto compatible!

wow that is very nice. For me android OS should be already in cars. Couldn't find info about the price.

I'm in! Let's see what the pricing looks like!

Does someone know what kind of cpu it has, how much memory, 1 or 2 gb and how much disk space has it, 8, 16 or 32gb?

i just read a comment on their blog-post that this gem is cancelled ... shame shame! anyone knows more than me?

It's look like they will release RNB6 head unit in a few months.

that'd be great news ... if its below €500,-- its a deal for me ... otherwise will have to think first

I really wish these dudes would give us a release date! I don't have a lot of patience to continue waiting!

^^ I know right? Let hope it is less than $400 or 500. I am hoping that this unit will come with real traffic live, much more features than Pioneer's newest unit that came with android auto, and able to use the gps data without using the android phone data.

500 euro is much to low if you want that they use well know brands who are reliable materials like a fast quad core CPU, 2 gb DDR3 mem and at least 16gb of nand space. ( 32 gb should be a great option )
I think it will have a price tag between €600 or €1000 .

Does anyone know if there has been any further information on this.
I've been looking over the models recently and this seems to be the best one.
Looking for a new head unit for my new car but I don't want to be waiting until the cows come home only to find out its average

LOL, we've been reading about it since January at least.
So far, it doesn't exist.
Pretty much the only AA HUs are a few 2015 Pioneer units. (Besides my HU app with a tablet.

Hi there!
I know these sorts of questions tend to result in canned responses, for
dozens of reasons, but I fell I still need to ask.
I've been obsessed with the RNB6 since I saw the demonstrations at CES. I
search every week for info all over the net, and I still can't find a
single update since January. Is there any additional information, projected
release dates, or anything? I'm confident this will be next next car
entertainment system.
Thank you very much!

That does look pretty cool! Though I sure do wish I could get the additional cameras and awesome stuff provided by the Parrot option. This is really cheap though... hmmm Could be a great stop-gap measure.

Well... I'm worried about the overall build quality and the sound output.

[July 2015 update] RNB6 project was showcased at CES Las Vegas in January 2015 (watch video below). This infotainment system was selected by several automakers who envision to integrate it in their next-generation car models next year and beyond. As of today there is no plan to sell RNB6 in Aftermarket channels as RNB6 embedded technologies require deep integration with car series and manufacturers.

Damnit! I guess I have to consider a tablet setup again... I really wanted an all-inclusive solution though.
What's annoying is that all the articles I saw on this unit were talking about how you could upgrade your 'clunker' with a new radio... and now they announce that this is only going in new vehicles? That's absurd. Oh well.

New Joying Android 5.1.1 2GB Units available very soon !

Hello,
I found 2 new videos on youtube showing the 2 next Android 5.1.1 2G units from Joying (Boy Ka channel).
Joying announces a release date for october 10th.
The standard universal one (8 inches, 2 din) :
and the single din 10.1 inches :
I hope that they will release a dedicated unit for VW (with knobs for volume) and I will get one.

No evidence exists that these are 2gb units and when requested to produce a video the response is "some time", "later", "trust us" etc. Poster claims these are intel units and again no evidence. Suggest marketing is in action until supplier produces reliable information.

hopefully it is legit

They have a lot of units on Aliexpress listed as 2GB RAM for a long time now. I asked if these are really 2GB RAM and they said it is an error. I suggested that they correct the listing but I guess that still didn't happen....
Sent from my SM-N910F using XDA-Developers mobile app

It is strange indeed, Joying has lied about these specs before, so that's nothing new. However the unit does appear to be very responsive, so I take that as a good sign. Let's wait and see what they come back with on October 10th and I'm hoping they come up with a unit for the Sprinter/Crafter...

I do not doubt joying a second what they specify. The system looks extremely responsive. Probably totally true that it is a intel cpu with 2 gb ram.

Yeah, no kidding. I actually bought one these from Joying, specifically their 10" Unit MTCD based unit running 5.1.1 thinking it would be an "upgrade" from my NewsMy CarPad 2S. Boy was I wrong. These units only have 2 advantages over the NewsMy. The RDS works and they are available in a 10" screen. In every other way, they are inferior to the NewsMy. The worst part is that the Internal Bluetooth adapter communicates via the MCU only. It is not visible to android, so any apps that need to talk to BT devices, such as my radar detector, don't work. The NewsMy was better because it had dual bluetooth adapters to get around this problem. Even the custom ROM maker, Malaysk can't fix this because he has tried and failed to inject generic USB bluetooth drivers into the rom to run dual bluetooth. So, now I am at an empass. Do I put my NU3001 back in and give up RDS and the 10" screen, or wait for this "new" Joying unit in the YouTube video that runs Intel SoC to see if they fixed the bluetooth problem...... I also emailed Summer at NewsMy asking if they are working on a new CarPad IV, hopefully with a bigger screen but no replies....... Don't know which way to go.

Interesting, in the 8" video he mentions at minute 3:40 that the first boot takes about 20 seconds, but that the second time it starts it just needs 10 seconds, and at the end of the video he shows how it goes up from standby in just 1 second. What type of boot is he referring to with the 10 seconds. Is he referring to 10 seconds boot time also when the car was off for a few days? That would be awesome, but I guess this is again just Joying marketing...

Would you be willing to do me an enormous favor? I have been struggling with the joying MTCD unit since April because one of the applications I need does not work. Specifically an app named alpconnect which I will link below that communicates with my radar detector via Bluetooth. The reason it will not work is because on MTCD head units the internal Bluetooth adapter communicates through the MCU and not Android itself. So when I open this app, after I accept the license agreement, it states that bluetooth is off when in reality it is on and then when you click allow it will crash. I would very much appreciate it if you could take a few minutes to try to install this free application and let me know what happens after you run it, accept the license agreement, and tell me if it also says that bluetooth is off or if it starts scanning and looking for the Bluetooth module, which would mean it is working. Thank you very much.

So basically they've kept the MCU setup and swapped out the ARM board for an Intel version.
Easily doable since the communication between the two chips is just a serial port.
Add Android x86 and apply the custom apps and away you go.
This unit might be interesting though, potentially able to run any OS that runs on Intel. That includes Linux, AOSP android or even Windows!

I Googled the build string in that screenshot and this came up:
https://www.alibaba.com/product-detail/7-inch-Intel-Sophia-3GR-C3230_60334463213.html
So I'm guessing the new units have a CPU similar to an Intel Atom x3 c3230

Phh 8.1 GSI is fully functional minus the camera you will also need to set a custom width to make the screen not super tiny or use my edited one below.
Phh 9.0 GSI works but with a few bugs primarily Bluetooth and camera. But also it has a wonky navbar and notification pulldown but those 2 are aosp bugs
I have edited the v25 phh 8.1 gsi and added ro.sf.lcd_density=320 to the build.prop which makes it so the screen isn't super zoomed in. I will work on doing something similar to vendor in the future so its persistent over all gsi's.

Thanks for doing this, hope to see how other ROMs function. Can you also test a Pie GSI?

Thanks for this, I'm considering getting this tablet. Could you possibly do a video review? There hasn't been a good one in YouTube yet.

I'm going to assume that you are the only one doing any development with this tablet? Which is fine either way, it just let's me know once I get my tablet, how long the wait will be or expect for custom ROMs. Thanks again.

I don't plan on doing a review or anything i got it to do development on it. GSI's are working on it, i am planning on getting a device specific rom up and running soon. Working with the hi9 air and hi9 pro devs to see if we can make something that is compatible on all 3.

Thanks for the update. Can't wait to see all what you come up with!!

I asked them directly about buying the keyboard case separately.
It's not listed on their official Aliexpress store so you have to buy 35 units of "Extra Shipping"
https://www.aliexpress.com/store/pr...l?spm=2114.12010615.8148356.55.63bb4c05f2hzru
And tell them you want a keyboard case.
Oh and thanks for TWRP.

Anyone that hasn't flashed anything yet, can you tell me the current security patch level?
I could swear that I saw June, but after flashing the rom provided by Chuwi it's at February.
Also it seems far more sluggish than it was before flashing.

Yeah the firmware they provided is older, the one shipped on the device was june i have asked for updated firmware and was told they are working on it.

No sadly, i am in the same boat i assumed the firmware would match what was shipped so i didn't grab one.

Let's hope someone else out there reads this before they flash.
Or Chuwi releases whatever is current.

NA

GSI is apparently doing some amazing work and possibly working around the clock. It's crazy to see that there is a partially working 9.0 rom( or lastest Android version) so soon after device release!

For anyone interested, I found the keyboard for 17 dollars, however the pen still like 27 dollars no matter where you go.

The problem about the pen is that you can use the tablet for 2-3 years maybe, nut if you lost the pen is very pobrable that you won't find it online after just 6 month, if it is not a chuwi standard (and as far as I can see it's NOT a standard).
BTW I have problems checking out the keyboard site, are you sure it's a sure online shop?
Thank you!

I just try and everyting was ok, but $9 shipping fees are pretty high. Grandtotal is ok anyhow due to the very discounted price. This is another addon that you might buy as soon as you can since it's already hard to find.
The rablet is sold at nice price by [email protected] and you can buy the pen as addon for €17 (maybe $20, but you save A LOT on shipping fees!!!)

It's just a normal Wacom active pen, I tried out my Lenovo one and that worked properly on it.

Low profile depth?

I'm looking for a 7" unit with a Rockchip px5 or px6, or the next best thing that has a slim profile like this, maybe 50mm or 60mm deep at most. What is my best option with this kind of size constraint? Do I have to roll the dice on some no-name ebay or aliexpress unit and hope the specs are real or is there a safer bet?
I didn't see anything from Dasaita or Joying that fit, but there's so many chipsets it's hard to know what is junk and what isn't.

I'm not sure there are any MCTD units with a slim profile.
the best units i'm finding are something like this wondefoo:

Yes, that was my takeaway as well, just confirming. Are there any MTCx units with a similar form factor to the units above? I've been digging through aliexpress/ebay/etc for hours and haven't found anything.
Other than joying, wondefoo, & dasaita, what are some reputable brands I can look for that will actually be the specs they advertise when I run CPU-Z?
Trying to figure out what the best unit I can get is with the tight space requirements. So far that wondefoo is the only one I've found by a "name" brand.
Appreciate any help.

Are you saying if I order the wondefoo unit directly from wondefoo it may not be the specs they claim?
It was my understanding that when you order from wondefoo, dasaita, joying, etc you at least get what they advertised. A lot of the ebay/aliexpress "no name" units are showing lower specs/api numbers when you use cpu-z. Is this an incorrect assumption?

Anything goes with these "resellers". There may be multiple "wonderfoo" resellers, which is irrelevant; what you want to know is the manufacturer of the unit, which you can only find from the MCU type. Read the wiki mate.

I'll start by saying I'm sorry if I sound like I'm pushing Ownice but that's what I have experience with. Their C800 high model is MTCE and low profile like the picture. You can buy it off Aliexpress from several sellers but I would suggest you look for the Ownice Official store (and not one of the ones from Russia or Spain...). On Aliexpress it's listed as the K3 I would give you a link but they have been requiring a login to show anything for a while now so it's no use. The K3 high is a PX5 and the pro is now PX6. Check this thread for anything related to it.
I don't know of any specific models and I have no experience with them but you could also check with Seicane.

You are a life saver. I've been drowning in forum archives, wikis, aliexpress listings... I didn't even think you could get the better chipsets in that form factor. Somehow I never came across Ownice. I will start chasing down some of this info, this is a great lead. Thank you for pointing me in the right direction.

Curious if this is a decent head unit that I can use a custom rom with.

I purchased this unit and it will arrive tomorrow. I am familiar with android phone roms and custom recoveries but the head unit aspect seems a little different in a lot of regards.
Is this a decent unit for putting a custom rom on to enable viper4android, root apps, etc?

Yes.
Vanku installs an MTCE-board with a Rockchip PX6-processor.
There you can install any ROM for MTCD/PX6/Android10.

I got it installed and am checking out the MCU version and it says it is an MTCH. I haven't read anything about the H version, only MTCB and D. I know on Android phones the version numbers can cause a brick if they aren't for the same model. Is it the same in this case? Probably would help if I knew what an MCU was to begin with, or what MTCB, D, H, E, and H were even referring to....

MCU-MTCH has started to be used on the new boards, I've looked at 4pda and MTCH-HT there is no newer or older update yet. You probably have current. I do not recommend using an update other than MTCH-HT as you write you could get a brick. Try to write to the seller, maybe he will give you an update. And don't forget to share it with us. Why do you want to update the MCU, something is working wrong? If everything works for you, don't do the updates, usually no miracles will happen.

No I'm not actually interested in updating the MCU, I'm trying to figure out what custom rom would be compatible with my unit. On a typical android device if something is of a different version than what the device supports for that version of Android than you can get bricks, boot loops, or specific things that will no longer work, such as your radio unit for phones, Bluetooth, wifi, sensors, etc.. so I assumed that the MCU is the same? It has to match the specific hardware? I actually don't know what the MCU even is. I'm just going on an assumption and don't want to risk bricking my unit, or at the very least losing functionality. I even looked into rooting the PX6 series units but im not even sure how to go about that. Some say there is software for it, others say adb, and others say apps like KingRoot but I have never liked those apps as they tend to install crap you don't need or brick units.

The online costum-ROMs for our HU are these from the users Hal9k and malaysk.
You can also install the stock-ROMs from the yandex-folder I Linked above.
Your mcu is up to date and does not require an update

It is recommended that you run the stock ROM that comes on the head unit for a few weeks to make sure there are no issues with your new head unit. Plus you might find that the unit does everything you want it to do with the stock ROM. Installing a custom ROM just to "to have a custom ROM" is not recommended. May want to consider your reason(s) for installing the custom ROM.

You don't need custom ROMs - there are no true custom roms for these, they are modified base roms of one manufacturer
these basically mask/ workaround problems and may not be suitable for you headunit

Ahhh ok thank you. That actually help a lot. I was debating just spending a couple hundred more dollars and getting something like the Pioneer AVH-2400NEX. The display on this is a little washed out for my taste, and the actual unit itself is a couple millimeters to big to fit a standard double din dash kit. Apparently that's a typical thing with the Chinese head units that I didn't know about. The measurements tend to be off on them and are either to big or to small to fit correctly. I was thinking the Pioneer would be a bit snappier and have a much better screen. This Venku isn't bad by any means, it's pretty snappy and stuff, but its not quite what I was hoping for. Anybody happen to have one that can tell me what they think if the unit?

I have the same HU as you and I don't like the launcher that is installed. Looks like the HT-ROM.
So I can understand and understand if you want to change the ROM. In the yandex folder there are some stok ROMs from other manufacturers.

There are a lot of good alternative launcher apps available on Google Play and can be installed without changing ROMs. I use Car Launcher Pro (there is a free version too).
