Right, a lot of Bose systems are 2ohm, also these units are only 2-3V output on the RCAs and a lot of Bose systems need outputs of at least 4v, also some Bose systems do not use RCA pre outs, they use speaker level outputs. you can actually buy 2 types of adaptors, 1 that converts the RCAs to speaker wires so they can go to the Bose amp and some that takes the amplified output from the headunit speaker level outputs and un-amplifies them then sends them to the Bose amp.

Probably just Eonon not having a clue about the firmware !

Right, I take it youve researched how to fit aftermarket systems to your car ? Cos fitting this is really no different to fitting any other system and I ms sure theres a way to integrate MOST and CAN Bus.

looking to buy a oem fit unit for my 08 highlander

I am considering these units

RoadNavi RNA-T1803	(szroadnavi)

Mekede MKD-8822A

this is the picture of Roadnavi about page

[IMG="szRoadnavi"]http://i1057.photobucket.com/albums/t394/lovemytechy/Highlander%2008/Radio%20Android%20Head/E97FFDF6-82A8-40B7-A418-DA2F65D0593A_zpsvqe2po31.jpg[/IMG]

I am still waiting for about pic from Mekede...

any idea if I can mod these and upgrade these using the files in repository? they are both the same specs as other units here.
[MTCB Android Head Units Q&A] typos1:
Yes, Mekede sell JY units, dont really know what the "RoadNavi RNA-T1803	(szroadnavi)" bit is all about, post the about pic and we ll be able to tell from the MCU version.
[MTCB Android Head Units Q&A] swanie2000:
Thanks for the Update!

I have also been waiting to see how this amplifier works. I needed to cut my stock antenna down because it was hitting the top of the garage, plus it looks better shorter. It worked fine with my factory BOSE stock head unit I took out.

Bummer, with the new Head unit the radio reception suffers. The radio reception is bad enough for me to just give up on FM radio all together. It would be nice to fix this problem, and keep my shorter antenna.

Only other thing with the radio app is the station name replacing the station frequency on the preset buttons. Kind of redundant as the same information is already displayed on the screen. It would be nice to just leave the station numbers on the preset buttons.

the picture I posted is from Roadnavi.. can anyone tell what it is? do I need other info?
[MTCB Android Head Units Q&A] typos1:
Its pretty deffo one of these types of units, not 100% on manufacturer, wont know until the rest of the "about" page is posted, that pic is of the lower part, the upper part tells MCU info.

Maybe "roadnavi" are behind the new "MX" units.
[MTCB Android Head Units Q&A] erick161:
Yeah that might help. And I keep seeing newer looking and slightly different looking headunits popping up.

This one claims to be a quad core 3188

I like the fact this is a 7" unit, but this says it only supports Bluetooth with their proprietary device and app??

There already is a guide linked to on the first page about how to identify different units by their backs, although a couple of new ones do need to be added, it would have helped you identify the first unit if youd read it). :) ga!nusha was talking about a guide about which seller sells which units from which manufacturer.

The first one IS quad core and has already been discussed several times in this thread, most recently only one or two pages back.

The second is an AN-21U variant and there is a separate thread for those units.

539 pages, no, no 1078 pages !! You must be reading this on a VERY tall screen if youre only seeing 539 pages !!

Where have you heard that ? We havent heard anything AFAIK, nothing not a single solitary word from ANYONE mod/admin etc, requests are simply ignored.
[MTCB Android Head Units Q&A] doctorman:
that has no DVD /cd drive
[MTCB Android Head Units Q&A] typos1:
Ah ok DSA, thanks for the info, I guess its basically the same software just with some differences to make it work on an RK3188 SoM.

You are totally right g00s3y.

But you havent thought it through - if someone had KNOWN just how popular these devices would become and that there were going to be 8-10 manufacturers of very closely related products, then a separate forum could have been started with different sub sections for different subjects, just like is done for, for instance Samsung, LG, HTC phones etc. But, without the ability to see into the future, no one could do that and XDA does not automatically open a forum divided into sub sections for every single device that comes out of China - practically impossible with so many products available. So, unless you are volunteering to spend what would surely be months and months reading the entire thread and moving all posts to relevant sub forums, or maybe reading the entire thread and then putting the entire forum into your own words spread across sub forums, or you invent a time machine, we re stuck with this dirty great long thread ! Actually I m not sure it would be good if you were to do that anyway - you cant even use the quote function properly, things might end up even more of a mess !! :)

A separate Android Headunit section on XDA would definitely be good though, it may come when all the big manufacturers start making Android Auto devices.

Seriously though, if people read the first page and used the thread search function to find their answer instead of just posting questions that have been answered before god knows how many ****ing times, the whole thread would be a lot shorter. That said, as I mentioned earlier, the front page could do with a little updating though, I ll pm pakidermo and ask him.

Um, probably not, unless it uses the same MCU and the same RK3066 processor.

LOL !

But this is the THREAD - he means a separate forum for these devices, with different threads for different subjects, a "HuiFei software" thread, a "HuiFei hardware" thread, a "HuiFei custom ROM" thread, etc, etc

And ? !

You said "technically jouyus was the only that makes OEM fit for highlander that was on the list no other manufactere is on the list that makes highlander fit", I take it from your post what you meant to say, then, was:

"technically jouyus was the only that makes OEM fit for highlander WITH A DVD/CD DRIVE that was on the list no other manufactere is on the list that makes highlander fit. they are all new", in which case I wouldnt have posted a link to unit without a disc drive.

But you didnt and I aint psychic !! :)

Only one person has mentioned them before a few weeks back, too new, could spend time Googling and try and find the manufacturer or wait til more info comes to light about them, sorry I know thats not much help when you cant downgrade and your unit isnt working. :(

I've received my powered USB hub today and tested it on my PC and seems to work. Just need to wait for my 12v->5v DC converter to arrive now. I have a couple of quick questions 'cos I'm a bit dim regarding electrics - What is the relay for and why the constant 12V supply? I was planning to wire it to ACC.
[MTCB Android Head Units Q&A] agentdr8:
Most ACC circuits are fused at 7.5 or 10A -- while a 3A converter probably won't push you over the current allocation, it makes sense to use the ACC as a trigger to a relay, and provide 12V from the BATT. No need to worry about blown fuses or overloading the ACC circuit that way.

[MTCB Android Head Units Q&A] g00s3y:
Thanks, but I know how to use quote. I just don't care enough in a thread that is already full of clutter and mess. The whole thread would be shorter if a proper section was made for it. Create the proper sub-sections and the developers can all create their own thread for their roms. In the general section, there can be stickies for common problems and how to fix them, accessories sub-forum, development sub-forum, etc...

No one needs to go through all these pages for everything just to create a dedicated section for it. Most of it is already in the first page. Not to mention, only the MCU cannot be interchanged. There are what, 6-7 "different" build types, which are interchangeable? Wouldn't really take long. Hell, if the mods just created the section I'm sure all of us would be intelligent enough to sort it all out ourselves...
[MTCB Android Head Units Q&A] agentdr8:
Agreed, but none have shown any interest in doing so to date. I don't think I've even seen a mod-edited post in this thread before, so it's possible none of them have ever looked at it.

KGL-7303

Hey All,

Ive been following this thread through all 1078 pages and decided to get me a KGL-7303 for my 2011 F150. Anyways I installed the deck and turned it on and the android display was backwards (mirrored). After shutting it off and reseating the plug in at the back of the hu, the screen went white and was turning white to black by flexing the plug in gently. Well I started to smell something burning and saw smoke coming out around the power knob. I contacted the seller and got alot of apologies and was asked to send a picture of my wiring harness connector on my pickup. Never did but anyways I decided to take the unit apart and see if I could find anything burnt up. I took out the two screws holding down the cpu simm card and found a burnt bit under it. Can anyone tell me what this three legged thingy is thats burnt up? I was so looking forward to using this deck. Thanks for any help.
[MTCB Android Head Units Q&A] agentdr8:
Wow, haven't seen any of these units go up in smoke before. It's possible the cpu module shorted out against the motherboard. Maybe your reseller would be willing to send you a new module? Should be plug 'n play. Also, if you were having display issues prior to failure, it's possible the display ribbon cable was not properly seated. I don't believe any amount of miswiring of the harness would cause the display to be mirrored/flipped.
[MTCB Android Head Units Q&A] typos1:
I was trying to be slightly amusing by pointing out your quote and ALSO your valid points, but frankly saying "I know how to use quote. I just don't care enough in a thread that is already full of clutter and mess" means youre nothing more than a total hypocrite.

Youre not doing anything other than adding to the "mess", you have nothing constructive to add and your rants at posters in this thread are aimed at completely the wrong people - NO-ONE on this thread can do ANYTHING your suggesting.

Either put your money were your mouth is and somehow get the mods/admins to what you suggest or frankly, just go away and stop making the thread unnecessarily longer with your "just dont care enough" attitude, hopefully you will "just not care enough" to reply.

BTW this subject is also one of the things that has come up frequently and the answers are always the same, for all the reasons that have been given in previous posts, so the sum total of your contributions to the thread are to make it unnecessarily 10 posts longer, EXACTLY what youre moaning about !! GET OUTTA HERE !!
[MTCB Android Head Units Q&A] KilrPilr:
I havent heard of any smoking up either but thats my luck i guess lol. Its hard to tell if the little tiny things on the cpu module are smoked or if its just the three legged thingy on the motherboard thats smoked or all of it. Ive emailed them asking for a new motherboard and cpu but will see what they will do.I could probably desolder the burnt thingy there and solder on a new one as im pretty decent with a soldering iron but i dont know if that thing burning up took out any of the other circuitry. Im actually concerned about plugging this into my $20k truck after this as it would truly suck if this thing burnt up my trucks factory harness somehow. Here is the only pic I got of the android screen before it totally failed. I kinda gave you the short story of how things went, but one time it booted I got this....

edit: In fact there was no wiring to do as this unit is totally plug and play. Only 2 plug in connections to make and its up and running. you cant go wrong. The seller said it was tested prior to shipping and was fine but I have my doubts. lol

You might have just made my day. I do have a GMC Acadia with Bose and I remember having to do something like this on my old Mazda 3. I'm going to try and change over to the low level outs to see if that helps the static and poping sound I get from the sub on some random sound actions from the UI. Also, where would you install the ground loop isolator on all this? By the way my unit is too an Eonon made by KLD. They just sent me some new software too to try and "fix" my static and popping issues.

---------- Post added at 10:07 PM ---------- Previous post was at 10:00 PM ----------

Yeah I've briefly looked around the few GMC Acadia forums I could find and that crowd doesn't seem like the type to tackle these mods. I'm going to try the low level out changeover and see where that gets me. Then I'll look into a isolator to see what that does. However I'm not real sure where in the system I would put the isolator.

Hello. I have the same problem. My battery is drained enought in 2 days stop, so that I can't start the car !

thanks in advance.

[MTCB Android Head Units Q&A] ga!nusha:
Yeah, they also tried to fix my issue via software. The popping noises you hear are because you don't use the pre-outs. That is for sure ! I also had them. Regarding the static noise, you should only have it while the enigne is running. It comes from the alternator. I have put my ground loop isolators between the preouts and the harness. The tricky part was to fit all of them in the dashboard. Be sure to buy ground loop isolators that have long wires and that are not circular. The circular ones are noise filters that will not work in our cases.

I know this was discussed recently - I've got a 12v to 5v USB adapter for my vehicle - but - where do I get a powered USB hub that runs off USB? Or how else do I get power to the actual devices, USB flash drive and dongle?

I can't plug them in directly to the USB power socket - cause they need to be plugged into the device.
[MTCB Android Head Units Q&A] Enc0der:
Just a quick question:

Is it possible to have the BT-Audio (media) always play in the background (even start "playing" automatically when a BT-Audio device is connected, but in the background) while still mixing with other apps (music, youtube, CD, etc) ?

I'm asking because I want to keep using my phone as a GPS (with Waze) while having the HU play music, that way I can take advantage of the 2 screens I have in my car... the phone's and the HU's... and I won't have to switch back and forth between Waze and the music player.

When my phone is connected to BT, Waze will play all of its sounds through the BT-Audio channel, so this is why I want to always hear it in the background (not just when switching the HU to "BT-Audio").
[MTCB Android Head Units Q&A] ga!nusha:
You can mix it with jet audio, YT and other 3'rd party apps by pressing home button but not with other MTC apps like radio, CD because they cancel each other out.

[MTCB Android Head Units Q&A] DJCannonball:
you refer to #10697 there's only 800x480 versions listed (I have 1024x600 screen)

anyway, i have some bad news. the firmware i got from my seller does also crash (but takes way longer to crash)

also i stated that the mcu.img that came along would not flash. that's wrong it seems that the img-file must be on the original sd-card (same card as GPS-software is installed) and only in the left (gps) sdcard slot.

so the mcu.img did flash after all (and it appeared to be version KLD V2.20)

it did fix the volumeknob to keep working properly, but at the same time the gps software steals the audiofocus again while playing music (even with the correct gps-mix settings).

one other thing: i also have flashed kld mcu.img v2.44 from post #10709 (which was intended for rk3188, not for rk3066)

that one seems to be running fine on my rk3066. my volumeknob keeps working properly, but the OS is still crashing ocasionally.

from this point, i'm beginning to suspect Sygic is being faulty/buggy. i will not be using Sygic for a few days and keep on testing to see if Sygic has anything to do with all the crashing. i'll keep on testing and researching to find the best combination. my goal is get the thing stable/failsafe.

All updates, MCU or Android must be on an SD car, ANY SD card in the GPS slot. The MCU is the same for ALL versions, RK3188 and RK3066, v2.44 is not "intended for RK3188".
[MTCB Android Head Units Q&A] DJCannonball:
some pages back, someone stated that KLD v2.44 was specifically for RK3188 and would be somewhat anxious to try it out on a RK3066.

But still i tried it out and seem to work fine on my RK3066 (left aside the OS crashing)

you stated All updates MCU of Android must be on ANY SD card in the GPS slot.

then how do you explain this: both update.img AND mcu.img where on a usb-stick. update.img flashed just fine, mcu.img did NOT.

then i moved both files to an sd-card, i put the sd-card in the other slot (not GPS-slot) -> none of the files would flash

next step, i put that same sd-card into the GPS-sd-slot -> update.img flashed just fine, mcu.img did NOT.

from here i copied the mcu.img to the original sd-card that came with the unit (same as where Sygic software is on) and put the sd into the gps-sd-slot -> mcu.img file flashed fine.

how do you explain that
