I want the poweramp,if i buy it then it works fine without wifi conection or it need always wifi conection to verify the activation code to sart work?
[MTCB Android Head Units Q&A] goolac:
HUMMM Never seen that one before. It has an M-Star CPU which is completely different than this series of units in the thread. I spent a few minutes searching for Dev info on the unit and can not find any. If the unit is working well for you then just use it and as it gains popularity, maybe some Dev work will be done for it.

I have to admit it is a good looking unit and with its specs, sure looks to be as good as the ones in this thread.

1024x600 screen

Going back to the whole 1024x600 screen issue, has anyone had any experience with the Tradesolution units?

For example, the T6602A unit (you'll have to google "tradesolution T6602A" as I can't include the link)

1024x600 resolution, Android 4.2.2

It's a different CPU, the Telechips TCC8935, seemingly not as popular as the RK3066.

Wondering if anyone has played with this unit? I'm sitting on the fence between these and the HuiFei lines of products.
[MTCB Android Head Units Q&A] kwalsh24:
Same here, any units with the better screen resolution is using the telechips processors, which has next to boning for hacking support
[MTCB Android Head Units Q&A] Sengir:
Thank you,waiting for photos :) anyway I just ordered it from Key Lo with 3G dongle,the unit will ship tomorrow.

I came from a Pioneer unit that I'm almost satisfied of in sound quality,I hope I will no regret buying the HuiFei and that the quality issues are fixed with these new models.

Be careful the Telechips TCC8935 is 1.0 ghz dual-core, not a 1.7 as written on the page.. smell of scam?
[MTCB Android Head Units Q&A] webdude12:
Ok, Im getting a ton of questions about the unit s that I am in talks with from an un-named manufacture. The reason I do not list the name is, they will not sell single units ever, nor will they sell to anyone without a business license, etc. The estimated order size will be 144 units min. As I stated before this not a unit you will find on Aliexpress, etc.

They are telling me its going to be late Jun / July before I can get an engineering sample. The only reason they are even considering me for that is because of the recommendations from my friends in the car audio industry that I built through the years and they know I am interested in becoming a US Online Distributor for them. But even if I dont become a distributor, for the US people, I know a few companies that will and can sell you one through a local stereo shop one released.

The latest specs I last got as as follows:

Dual Core 1.6 Exynos 4 CPU

2 GB Ram

16GB Storage (OS and stock apps using approx 4.5GB)

1280 x 800 IPS Display

Android 4.2

4 x 50 Audio

5.1 output via RCA

4 - USB Ports (3 Back - 1 Front)

Support for Can Bus

Dual Zone Video

Backup Camera

Basically everything you are seeing now. The difference will be the components used come from an OEM car stereo manufacturer. They have made radios for 30+ years Target Retail Price is going to be more though. Estimated that unit for my Audi A4 is going to have a retail of $899.99 US (Street Price of $750 - 800). They are saying I am going to have to probably pay around $450 - 500 for my engineering sample. This basically be a unit that all the hardware will be 100% done, but software maybe buggy, with dealer cost being in the $550 range before shipping (Depending on quantity ordered). This basically falls in line with the rest of car stereo market that has a general profit margin of 30 points (Not %, but points - look it up)

They are actually developing these units for a well known company that already has a Auto Dealer support line that runs android, but its currently 2.3 and highly skinned where you have no way of even knowing its android. They will come stock with a similar skin on them, but the manufacture understands that if they can make it developer friendly, they can not only sell to their primary source, but also sell units to the general public, that typically do not goto their dealer for a new stereo.

As of right now the target release date for their OEM company is CES 2015, but they are telling me sometime late 3rd Quater / 4th Quarter might be a more realistic date that I can order.

If I get any more info, I will update, but currently that is all I have, and all expect to get until I can get an engineering sample. I will not be responding to any further PMs on this radio. Im not trying to be rude, etc. But I cant answer questions that I do not have the answers too.
[MTCB Android Head Units Q&A] pakidermo5000:
Thanks a lot 1-2-Hak !!! Got it !

Now I understood. So, the point of installing TWRP is, at the moment, to just backup and flash via adb in recovery. This is not really needed to back up as there are other means to back up. I found at least 3 other ways on line. see https://sites.google.com/site/tweakradje/android/rockchip-device

1- adb, you can copy the partitions into images (1 at a time) and then move to your sdcard.

2- there is a script to be used with adb that automatically does the back up of all the images at once.

3- use nandroid backup from Google Play. If you choose TWRP, then you are good (and I guess is equivalent to installing TWRP and doing the backup).

More things: I installed Harker´s update (I did not install mcu, yet).

- Booting time is of 24-27s (not 15-18s).

- Radio app now stores station names !! yey !

- Loud option of amplifier is not saved

The rest seems to work as fine as before.

Do you think that updating the mcu will reduce boot time ?

Edit: maybe I misunderstood a previous post of yours 1-2-Hak. Did you mean that with harkers update your booting times did not change? or that booting times of Harker update were similar to yours ?
[MTCB Android Head Units Q&A] stollerolle123:

It reduces boot time to 15-18s and fixes microphone issue with android not seeing it.

Download here: http://goo.gl/ilcqoD (thanks to [MENTION=479834]hanker[/MENTION]s

PS: there are 2 kinds of "update.img", for bmw benz model, choose the "update.img" from KGL1. for other car makers, choose the "update.img" from KGL
[MTCB Android Head Units Q&A] 1-2-Hak:
Your should do the mcu as well. There are a matching upgrade - there are things in the android apks that refer to new functions in the mcu.

Great to hear you understand TWRP. It is helpful for me with my hacking as it is a quick way to recover from boot loops. I just go to recovery and restore.

I found the new update to be the same boot time as my modded image around 15-18 secs

Didnt have much time to play with the update as the unit dided not long after I had installed it. Hopefully have parts next week to fix.
[MTCB Android Head Units Q&A] genge:
Can i update it without mod recovery?
[MTCB Android Head Units Q&A] pakidermo5000:
Yes you can. But I would advise you to first do a backup of your system and learn to boot in bootloader mode. If something goes wrong while you are updating and you get a soft brick, then you will love to have the possibility of flashing or use TWRP and a backup that will just recover your unit in a few seconds.

So, you do not need to install TWRP, but you must make sure that if need be, you will be able to flash partitons. So:

- check if you can boot in bootloader mode

- do a nandroid back up, or use wifi adb to back up your partitons.

this will allow you to flash any partition and recover your unit. Ultimately you can use bootloader mode to flash TWRP recovery and then recover your nandroid backup.

How to get into bootloader mode:

1- boot the unit as usual.

2- plug the front usb of the unit to your computer usb.

3- Then, push the reset button and the power button at once and keep them pushed. The reset button is the tiny pin next to the mp3 sdcard. The power button is the volume knob. You will hear the power cut throught the speakers.

4- Release reset button and keep power button pushed. Now the unit will reboot. You will see nothing, just a black screen. Do not release the power button yet. Your computer will detect a " new hardware", that is the RolckChip. When you hear the windows noise of new detected hardware, you can release power button. It will automatically install the drivers.

Congratulations, you are in bootloader mode, and on the safe side.

Extra info:

- backup apk and system data (Titanium is your friend) because your /data is formatted while updating the system

- you will probably need stock recovery instead of TWRP to flash MCU (not sure TWRP can handle mcu.img). So, either do not install TWRP, or reflash stock recovery when you want to flash mcu.

- If you want to flash TWRP, follow 1-2-Hak post.

I hope this can help someone, it took a while to me to figure it out...
[MTCB Android Head Units Q&A] kwalsh24:
Thanks for the info, makes me wonder if all the 1024 units are scams then, as they all seem to use that chip... sigh I may just have to settle for a 800 unit unless anyone knows of any unit that's using the 1024 screen resolution.

Green point has a Sino unit that uses a mst786 chip and they say its a 1.2ghz. Anyone have any insite on this chip?

(http://www.aliexpress.com/item/2014...player-Car-Stereo-for-MAGOTAN/1740743960.html)

So i must ask ask this to the users who own the huifie unit now and have been using it.

Out of the box, does the unit work without needing any modifications? I'm looking for a unit that will just work. FM & GPS simultaneously, SD music & GPS simultaneously. I don't plan to load a ton of apps on the unit so if the 800 unit works then I may just get it for the $440 on aliexpress

Now if I do get it, and if I were to doone thing to it (other than root & install twrp) what would it be? What would you recommend ?
[MTCB Android Head Units Q&A] MMouse:
Thank you for your post. It was very helpfull

How do i connect USB if i dont have a front port.

I only have 2 in the back, which are nor normally connectable because they are female type A.

I own the KGS8401 Huifei VW, it just came in.

sorry something came up (and working on tuning the OS of course

Well no issues so far, the only downside was that my unit only has RCA Rear out and no Front, the rest is fine.

I am using an amp that supports high in, so i will stick to that.

Let me know you want more pics.

As for the 3g stick, yeah i picked the stock one also, but i prefer the huawai e3131 that has an external antenna connector.

One more question, does anybody know how to regulate separate volume settings, my call volume is extreemly loud compared to everything else.
[MTCB Android Head Units Q&A] MMouse:
Hi,

FM works simultaniously with IGO, when igo has sound, FM is muted

Video`s and IGO does not work, it will stop the video

As for music, i expect it to work like FM, but i cant test right now as i am still putting stuff on my external HDD

Edit: Music is the same as FM, it decreases volume when IGO is running.

The 840x units are fine, the picture is great, yes some apps only show 3 or 4 lines of text

But i find Xposed with Appsettings a perfect solution, it allows you to change DPI per application.

I changed just some apps that i would like to show better on the 840x screen.

Also once you have Xposed many more apps are available that allow you to change the dashboard etc.

Xposed is something that can softbrick your device.

But each app lists its own risks. the framework itself does not have any impact, it only allows the modules to be enabled.

Also the stock Igo is the free version i replaced it with a cracked version allowing Internet traffic.

With the right version, this will not break your Nav button.

Let me know if you need a link for this.

I still need to go for twrp so no backups yet (lol)

Overall, it doesnt get much better then this. Everything you could expect works.

-There is no 32 GB limit

-The resolution is fine

-The screen is great.

-This forum is great!

-Because of Android, anything will work, as long as you use your creativity.

I still have it on my desk as my car is only comming in next week, then i will share about VW integration / Cambus / Torgue.
[MTCB Android Head Units Q&A] kwalsh24:
Mmouse, thanks for the update! Would like to see a before and after shot of the xposed app at work to see what it makes the apps look like if thats possible ?

Also if you could pm the link to igo that would be awesome :D

Now should I order from aliexpress or from Keylo email address? I see on aliexpress the units are 440usd shipped. Does Keylo offer different prices directly ? I never did get a response to my question on pricing when I emailed.

Mmouse, where did you order yours from? The lack of front USB port is a bummer, as the rears might not allow for PC hookup? That was the exact model that Keylo quoted me in email, the unit on aliexpress has a different model number but wonder if its the same.
[MTCB Android Head Units Q&A] Dareksa:
Have you tried to change something in the hidden menu (126) ?

For example Keymap in Others or settings from the Audio tab ?
[MTCB Android Head Units Q&A] pakidermo5000:
According to the fotos (a bit dark) I see that you have buttons, so probably the ones at the bottom are not real buttons, but little doors that if you pull will show the SD card slot, and the micro USB, and the reset button. This is the usb you have to use.

Edit: Ok, I see that your sdcards are next to the DVD as well as the reset button, so no miniUSB. I reallly do not know how you can do it, probably you can just enter bootloader mode by pushing power button and volume down. then, maybe the rear usb can be used to connect to the computer. You need to try... or ask your seller. There must be a way you can enter that mode.

Video Out problem

Hi everyone, I already use this unit around 1 month, and until last week nothing problem with it.

But when I connect it with my head rest monitor, I got nothing but blue screen.

I'm sure I connect it with the correct connector & connection

Does anyone have this kind of problem?

My communication with the sales person still cannot answer my problem.
[MTCB Android Head Units Q&A] lucky-jon:
'The HuiFie Unit'..... I am not sure (having purchased one myself) what is The HuiFie Unit. I assume here we are talking about units that are firmware interchangeable. Same chip sets, same bespoke hardware, but may be not the same physical design, sockets, controls, wiring etc.

It looks like there are companies that buy the same basic chassis from its manufacturer and mod on their own options - which may or may not make the units incompatible to some extent with hacks here.

I purchased my unit from Georges at www.android-caraudio.com. I sent an email to Keylo's email address on a technical matter, and within hours it had been passed on to Georges, so clearly they communicate with each other.

I wanted my unit to work 'out of the box' but also have the option of tweaking and modding at a later time. Also, having a well hacked, virtually 'open' unit is very reassuring to me, given that once a product is dropped by it's suppliers, their only interest is to sell you something newer.

Yes, using unit as supplied, GPS, radio, bluetooth all seem to work together sensibly and pretty well.

Apart from an issue getting my power control sorted out (accessory power), I am happy with the version of the HuiFie that I got. Tell your seller the exact vehicle and configuration that you need the unit for, then they can make sure the one you are buying is the best one. (correct cables, exact fit into dashboard, correct options (canbus) etc.
[MTCB Android Head Units Q&A] kwalsh24:
That's my one only concern, is getting a unit that works seamlessly well with my 09 jetta & its canbus system.

As even tho they are pictured with them, they may not come with them

[MENTION=853627]coudu[/MENTION] the oem.img (filesystem) appears to be roughly 48MB and gets mounted at boot. This would be an ideal location to put the stock recovery and twrp recovery images, along with some simple scripts to flip between the 2. I could even whip up an app that could be used to switch between them and reboot to recovery. Might make that space more useful to everyone.
