It would require decompiling the MCU code, understand what needs to be changed, and recompile it in a way that won't brick the unit when flashed. Way back when the thread started, someone [MENTION=3077590]darkleo2000[/MENTION] had made progress with decompiling an MCU image, but I don't think anyone here has experience or understanding of the machine code.
[MTCB Android Head Units Q&A] Enc0der:

I hope it is okey that I post this here, but I'm not completely sure that these units are HuiFei units.

I need your help to decide which has the best hardware, and which has the best software.

I don't like the way their software looks, and would love to be able to flash software from this thread, is that possible?

1st version (notice the SD-card slots at the upper left and right corner)

http://www.aliexpress.com/item/10-1...yer-For-Volkswagen-VW-TIGUAN/32291962426.html

2nd version (doesn't have these slots, seems to be a totally different unit)

http://www.aliexpress.com/item/10-1...Volkswagen-Tiguan-2013-Audio/32279473398.html

3rd version

http://www.aliexpress.com/item/Pure...r-For-Volkswagen-Tiguan-2013/32258249344.html

All these three are specifically for VW Tiguan. Have not found much information at all about them, would love to see them in action if someone has one!

Thank you very much, and again, sorry if any of these units doesn't fit here!

Read the front page, it tells you how to identify the units, there is a pdf and you will be able to identify whether they are the units in this thread or not using the pdf as a guide. As has been said before, the units in this thread ARE NOT just HuiFei units.

Viper4Android + BT autoconnect

I played a bit with V4A in last few days. At first I felt the sound is much clearer, but the treble was too much. I can't set it via V4A's EQ. But today I tried adjust the EQ in Poweramp while V4A is running, and I'm happy now! The sound is quiet good!

About BT autoconnect. Very strange. My phone has been autoconnect for more than a week after fw upgrade (Coudu's 4.4.4 v4.2 KLD + MCU 2.40 KLD). But last few days I had to step in BT app and press the connect button manually. What I noticed the WiFi is disabled if BT not autoconnected. I read there are other XDA members who has the same trouble with BT autoconnect. Does anybody have a solution?

Looks like there is a qualcomm som. Anyone think we could get this guy in here? Looks a little big, but definitely the proper 204 pin so-dimm form factor.

Hell, I'm contemplating cutting a hole in the metal housing and letting this stick out.

The main reason i would want to use a qualcomm chip is android 5.0 and future android support. So, if someone could just get android 5.0 on the rockchip, that would work too.

It would be much easier to use the RK3288 SoM from the Radxa Rock, 1.8 Ghz up to 4Gb RAM (safely overclockable (ike all Rcokchip chips, with extra cooling), but youd have to know what youre doing even with that. I think making the Qualcomm work would be much harder.

Pairing other BT device?

Anyone able to pair other BT devices? I am trying to pair the iRadar 100 radar detector from Cobra but the system won't pair. i have my phone and the OBD adapter paired OK. Tried searching the forum but not many people trying to pair other device beside phone and OBD.

I'm on a KLD with coudu's 4.4.4 ROM with MCU version 2.30.

Any clue?

Thanks..

Hi typos and bhitman, the problem is not attenuate intensity, the problem is the light of unity is always on when I roll the key to position 1, with version 1.86 never happen only when I connect the car lights at night, radio does not have be the lights always on...

i send email to KaiGeLe (http://www.kaigele.com/enus/index.html) about the problem, I'll wait to see what they say..
[MTCB Android Head Units Q&A] agentdr8:
I've tried other serial BT devices (like my V1 BT adapter), but even if I can get it paired, it won't pass traffic. It's most likely the SPP implementation that is being used with these BT adapters that's non-standard compared to every other android device out there.

What would be nice is a custom rom, with a standard BT stack, and kernel support for the BC6 module. Of course you'd lose MCU-integration, so things like audio routing wouldn't work right, but at least it would be closer to normal BT behavior.

[MTCB Android Head Units Q&A] kaween:
2nd one is a AN21-U design and is not related to this thread. Third one should apply to this thread and discussion.

The first one is an odd one : it has the complete software design of the AN21-U, but is stated having a Rockchip 3066 design. I don't think that is possible : one of the info sections is bound to be incorrect, so I wouldn't trust the first link anyhow. Especially not because in the first lines, the seller does not state a 3066, but a MST 786 at 1.6 Ghz ... which doesn't even exist.

The problem with identifying a unit is you depend on the sellers' ability to give correct info, and you have to have a bit of background info to be able to judge if the given info even makes sense. The link of the first unit is an example of a sellers' info that does NOT make any sense at all.

By the way, I concur with dsa8310 regarding the unit he linked to. In terms of hardware, that unit is definitly one to consider.
[MTCB Android Head Units Q&A] DJCannonball:
I did some extended testing the past few days. The quiting apps, the bootfailures, the Bluetooth stuttering and the complete os-crashes might not have anything to do with heating problems after all.

I was close observing the memory management of my Hu.

It has 8gb of nand flash memory, and 1 Gb of ddr ram memory.

If you add the amount of used ram. To the amount of free ram, it would represent the total amount of ram installed right? I have checked this often.

Sometimes the sum is 512mb. (while it should be 1024 mb)

And sometimes the sum is actually 1024.

This tells me that half the memory might be failing. This would make perfect sense why I have these problems I mentioned.

Check these images:

Here the sum is 512mb

Here is the sum 1024 mb

The sum keeps changing between 512mb and 1024 mb

I don't want to open the hu to keep warranty, but I was wondering if the memory banks could be replaced or upgraded.

My seller is contacting an engineer to sort it out. Maybe there is a bad contact/clip or loose part inside?

Did you find a solution to your Rocket Audio (sorry was away for a week and just caught up with the thread)

I had the same issue and found the solution by tinkering. Mine was crashing when playing *anything* and the solution was one of the audio settings in Rocket.

I think it was the one in the attached image (Dont have it installed anymore) but im pretty sure that was it.

Its worth posting in case anyone else has the same issue with Rocket Audio and searches the thread.

Having said that i tried quite a few audio programs and ended up with Jet Audio

It ticked most of the boxes as far as display and album selection. (Im using the Material Designs modded Jet Audio)
[MTCB Android Head Units Q&A] starfox5194:
Looks like you may be definitely on to something. No, the ram is not easily replacable unless you replace the whole android module in the nav unit. That process seems to about the same difficulty as upgrading some laptop ram. The problem is no one can find a place to purchase just an android som.

So, in you case, I highly suggest trying to figure things out with the seller.
[MTCB Android Head Units Q&A] DJCannonball:

Just return your unit as faulty for god's sake !!
[MTCB Android Head Units Q&A] DJCannonball:
if i would send it back, it would take 4 weeks to get the thing to china, they would probably take 1 week or so to troubleshoot/fix the problem and then it would take another 4 weeks to get the thing back to my door.

my best guess is it would take another 9 weeks before i get it back.

9 weeks without any music in my car. i drive about 4 hours a day. imagine it would be horrible to wait that long.

you see, i would like some other quick fix. if it's just a loose component i'd like permission to open it up and fix it my self in just 1 hour including taking the unit out of my car and putting it back in.

yesterday i got an email form my seller, they are on holliday till monday.

i will get an answer this monday, if they say yes, i'm fixing it myself, if they say no then i have to send it back.

this is apparently the main disadvantage of buying something from a store on the other side of the planet, i gotta have patience
[MTCB Android Head Units Q&A] DJCannonball:
i know that free ram fluctuates that's a given

but don't you agree that at all times, the amount of free ram added to the amount of used ram is representing the total amount of ram? that's no rocket-science

the strange thing is, sometimes the total ram is 512mb. when it crashes again (or justrebooted) i check it again... and sometime is not 512 mb but after reboot 1024mb.

haven't you seen my 2 pictures in previous posts?

Hi guys, just got an erisin unit from my astra and looking for a little help. I haven't modified it at all so it's still running 4.2. I had it all working but now I can't get any audio on my igo primo. I have gone into the GPS settings and it's set to mix. In the app itself all audio is enabled. I tried Nokia here and it's the same -no audio. The only thing that I dId between working and not was to pair my phone up.

Any ideas?

Thanks for the reply. I didn't play around with any of the settings in Rocket Player, but will try this fix in the future. I also stuck with Jet Audio. The fullscreen interface is perfect, imo.
[MTCB Android Head Units Q&A] DJCannonball:
Actually.. It was a banana.

I'm not *****ing about 512 mb missing. It seems to switch on and off. Like a strobo.

I could live with just 512mb ram. No problem. But if it keeps switching between 512 mb. And 1024 mb. Any os would crash. If any app was running half in lower memory. And half in the upper. And suddenly take away half the ram, don't expect the os to stay stable.

Another example: boot your computer, start any game you like, and while it's running, Pull out half the memory dimms... It Will crash instantly.

I think the same thing is happening to my Hu. It would make perfect sense to all hu's problems

You wouldnt necessarily have to send the whole unit back you could just send back the SoM.

You keep going on about not wanting to open your unit cos of the warranty and yet you REFUSE to use your warranty because you dont want to send your unit back ! What is the point in trying to preserve a warranty that you are never going to use because you dont want to send the unit backl ? !

What payment method did you use to buy it ?

That link (link) posted before as NOTHING TO DO with the rk3188 chip!

This is just the "2GB RAM + 16GB FLASH" upgrade item for their ALREADY-RK3188 units.

If you thought that you can buy this is upgrade your RK3066 to RK3188 then you misunderstood the entire point of this "item". This is just a "memory upgrade" for their units, much like the "HD Resolution upgrade" items in some 800x480 units.
[MTCB Android Head Units Q&A] typos1:
It is not his fault, DSA suggested it, you can see how the conversation evolved by reading the last 10 or so pages. DSA is fully aware that it is an upgrade for purchasers of new units and that it is not available separately, he needs a replacement SoM and he is trying to get one, he just came across that and was thinking that he may as well get a quad core SoM as he needed a replacement, dont know why I repeating what has already been written !!
[MTCB Android Head Units Q&A] Enc0der:
This is not the issue at all.

The fact that it's "not available separately" is irrelevant! because this is NOT an upgrade "from RK3066 to RK3188" at all - sold separately or not!

This is just an upgrade from 1GB RAM + 8GB FLASH to 2GB RAM + 16GB FLASH, for their (ALREADY) RK3188 units.

DJCannonball obviously did NOT understand this (because he wrote: "interesting.. 37 dollars for a new board containing a rk3188 2gb ram and 16gb flash is not very expensive.") so this is why I explained it so he will understand his mistake.
[MTCB Android Head Units Q&A] typos1:
Yes, there are lots of things he doesnt appear to understand !

What IS relevant is that to calculate the theoretical price of an RK3188 SoM with 2Gb of RAM bought separately, you would also need to add the cost of the RK3066 SoM.

the first picture represents the motherboard of his PureAndroid HU.

i see a replaceable board with a RK3066 chip on it AND some memorychips on the same pcb.

is that so wierd to think that a RK3066 hu with 1gb ram could be upgraded to RK3188 and 2gb ram by replacing this board with the one form the 37 dollar advert??

ofcourse i know that IF they would sell the pcb seperate, they would charge way more than just 37 dollar.

i was just wondering IF they would sell this pcb seperate at all.

theoretical it would make sense, but perhaps RK3066 pcbs are not inter exchangeable with RK3188 pcbs

So, been playing with my Joyous for the past week, tweaking and testing. Finally got everything working well except for steering wheel controls. I've got a 1998 Buick Regal GS and they have (what I'm assuming) are resistive controls. I have one wire in the stereo harness that goes to the SWC.

So far I've tried connecting the SWC wire to the head unit's:

- key 1

- key 2

- key1/swc wire and key2/ground (and reversed)

I do not seem to be getting anything. I do actually get a keypress registered if I have the SWC wire connected to one key wire and touch the ground with key 2, so at least something is happening. =)

So, what are the specific head settings that affect the SWC settings? I know under the factory settings we have canbus (which is not in my car), and I also notice keymap settings and am curious if these also are part of the SWC settings. I don't mind testing each one, but before I waste all that time I wanted to verify the settings have anything to do with SWC.

Anyone have any experience with these units with late 90's/early 2000's GM SWC that have got them working without a PAC?

BlackArrow, did you ever get a reply on the video color issue? I just got my Pumpkin unit last weekend and everything is working fine, but I just played a YouTube video for the first time and the faces/skin colors are WAY off for me as well. Colors look good in every other app, but the videos make everyone look like Shrek (green skin tone).

Can anyone else comment on this issue or have a resolution? I searched the thread and didn't see much on the issue.

Update: I downloaded the YouTube app and tried playing vids and the colors were normal. Must be something in the way the built-in browser displays videos.
[MTCB Android Head Units Q&A] typos1:
The keymap settings are nothing to do with the SWC - you programme the SWC to have whatever functions you want in the SWC list, so there is no keymap for SWC.

I can help you with your problem but only to tell you that on wire SWC has been mentioned in the past several times and a solution has been posted, I ve been reading the thread for a long time, so I know that for sure. However I obviously cant remember exactly when it was mentioned or who mentioned it so I cant direct you to specific posts. I would just search the thread, thinking laterally as to which words you search (maybe "single wire SWC" or "one wire SWC" for instance ?). Or Google it, as some cars do have only 1 SWC wire and this part of the stereo is the same as any other aftermarket headunit in that respect so the solution should be the same.

I have an 2003 Hummer H2 and it had one wire SWC's. It had a different voltage for each key press and I could not get it to work either. The deck could see and save the first button press but it all looked the same to the deck so when I try to save other buttons they all recorded as the last button press. I had a old Metra adapter to interface the aftermarket stereo to the stock amplifier but it didn't do anything with SWC's. So I bought a PAC adapter with SWC's work fine now.

I do have a problem that I think is the PAC adapter doesn't always get the stock amplifier turned on. You can hear the bass from my aftermarket amp and sub but none of the stock speakers work. You have to shut the car off and then right back on and it will work. Kind of a pain.
