[Q] Chinese ISC 4.0.3 tablet issues

Hello. I took a gamble and purchased a no name tablet off ebay. It said it has Android 4.0.3 OS, WiFi, FM receiver and GPS. I was going to use this device as a car pc of sorts but I need a couple things to work that I just cant get figured out. The module in my car either has to be connected with bluetooth or WiFi (ad hoc). Also the FM feature will only transmit to a radio and not receive radio stations. It just gets an error and closes the app. Also the GPS has been searching for satellites for about 2 hours now and never gets connected. Is there any way to fix the Rom or kernel to get these items working? I have also tried connecting a bluetooth dongle via USB? The device is rooted.

Allwinner (A10 & A13) is a relatively new entry in chinese markets (from 2011).
Allwinner provides the standard Android and Linux sources to OEMs and are available open online.
github.com / allwinner-ics
github.com / amery / linux-allwinner
But both GPS and FM are external peripherals as far as Allwinner is concerned. Hence both the hardware and software details will have to be obtained from the OEM for your tablet.

I will try emailing the seller to get these details. Is there any way to view the chip on the motherboard to tell what it has? Or maybe find out another way in the software?

I finally got the device connected to the gps and it found my location (even though its about 100 feet off) I would still appreciate help either identifying the device or help finding a way to connect it to the device in my car.
Thanks again.

Here are some pics of the device:

Control of stock Peugeot 308 LCD Display

Hi Guys,
I have a PX3 Android 7.0 Device with 4 GB Ram and 32 GB Rom. The unit is working now in Peugeot 308 with an LCD small display in the center console. It shows some stuff like Clock, media info playing, some information for the status of the car, Temperature and stuff like this.

I have seen that these devices have a software with touch buttons which help to go in the menu of this LCD display - but i cannot find this software on my unit. I know that it has to be activated via the Factory Settings menu (Code 126) - but really cannot find the correct can bus setting with which i can see this working. Could someone help me with this ?
I think it is the same also on some Citroen cars.
Thanks in advance for the support.

same problem here with a Witson unit the worst is the you cant change the clock.
The only way to change the clock is by installing the original stereo!
the km/miles per hour also does not toggle . even though i know it can do it, if i reboot the device and look at the dashboard the trip computer toggles between mph/kph several times on its own for about 5 seconds.
I have upgrade my mcu and now im testing different settings in the can bus department.
another od thing is that my Peugeot partner only works when set as a 3008 on the can-bus setting.
ps,
tomorrow i will post the name of the app.

Hi, do you have any progress with this issue ?
I saw in Youtube some android devices installed on Peugeot - having this option working. They have the icon : Control Settings - and in this application there are the buttons with which all the settings in the Up LCD display can be manipulated. I have this application - but do not have the software buttons.
Thanks in advance for the support.

I made it. Please try the following CAN BUS setting in the Extra Settings :
Canbus 61 PSA_301&2008&408
Type 5 3008
Key mode 508/2012
Swap_key Normal
Then go to the Control Settings application and you should see the buttons with which you can make all the adjustments.
Waiting for your feedback.

How to change the language for the peugeot car dash?
Used to be able to change with the original radio but couldnt with the android head unit.

Unit checks all the boxes but is it a good buy

I need some help with my first Android radio buy, so i ask my question here.
Want to buy this Fongent PX6 (RK3399) 4GB/64GB universal 2 DIN unit, Its got everything i want including all the connections i need.
Its was not my first pick, as i was looking for one of the more common mentioned units that i fount after my primarily research, but this unit got all that i need and is reasonable cheap, and got 5x USB, a plus but not a must, if there are reasons i should not get this unit.
These are all the parts i wane buy for the build, maybe there are some comments on the parts i picked.
(This are the parts listed in the link above, but the link dose not work all the time.)
Head Unit.
Unit bezel.
1080p DVR 2x.
back up camera. (Met Dynamic Trajectory lines)
DAB+
TPMS. (tire pressure sensors)
USB panel socket.
beckup camera power filter. (for €2 why not)
Panel removal set.
Spec.
Android 9.0 OS
Hexa-core cpu rockchip PX6 RK3399 Dual-core Cortex-A72 tot 1.8 GHz Quad-core Cortex-A53 tot 1.4 GHz
GPU Mail-T8640MP4

}
And these are the units connections.
The questions i am left with after 2 weekends research:
Do you have normally root access to these units, at minimum wane install a firewall, but a upgrade path would be nice.
Can you install different ROMs?
Unit comes with a Toyota cable set, are these standard connections for all normal Toyota models. (Have a Avensis 2007 / model type T25)
Can i keep using the controls on the wheel, or do i need a extra box?
Can you record 2 USB DVR streams at the same time on the unit? (would be nice extra)
Are the USB DAB+ dongles similar in quality, or is it, you get what you pay for.
Lots of questions, but Android car is not your standard PnP drop in unit.
Any questions people can help me with would be appreciated, greetings Michael

MTCD Device Identify

Hi Guys and Girls,
So I've just bought a 2010 Ford Focus and purchased a radio from the good old gumtree out of a salvage motor, mondeo I believe as it came with a mondeo labeled canbus decoder.
The radio is brilliant just a tad slow as it only has 1GB of RAM im guessing.
I've attached a few pictures of the unit and it's specs and software versions from the about page and wondered if anyone could fully identify it and point me in the direction of any custom ROMS or updates that might enhance the performance/sound of the device?
Many thanks!
Dan

Its a px3 device. Maybe the best you could do is change the coreboard for a px5 or px30 if possible. 1gb ram is really limiting and the px3 is maybe 5 years old and not that powerful.
You can try roms for px3, but don't expect miracles.

Would it be as simple as just ordering a px5 or px30 board and it working after installing it?(I've looked this up before) also should I opt for one with android 9 installed as I don't want Bluetooth compatibility issues which I've read are with android 10 if i remember correctly?

@pythoner Could you also please point me to where I could find a suitable coreboard for my device as a lot of them on aliexpress state that some will not support the current bluetooth or WiFi device I have installed?
Many thanks!

@pythoner
I have also discovered my device has the MD725 Bluetooth module installed and would this work or could I find a PX5 coreboard and downgrade its android version to say 7 for it to work again as I don't want to lose this functionality.
Thanks

Depends what type of MD725 it is and what Android version you use.

I'm unsure as to which version it is as it's current installed in my car? Would I have to take it out and open it up to find out? Also the android version is 7. Many thanks @typos1

Yes, I know you have Android 7. No opening required - install a terminal and type : getprop bt.md725.type and press return/enter, if its type 1 it works with Android 8 and 9, if its type 2 it wont.
Its very rare to have a 1Gb RAM version of a Nougat RK3188/PX3 SoM, someone may have even installed Nougat on an old RK3188/PX3 Lollipop 1Gb RAM SoM, but the usual 2Gb RAM Nougat RK3188/PX3 SoMs are not slow (theyre not exactly really fast but theyre perfectly useable), so if you can get hold of one of them its worth considering.

Aliexpress has px30 and px5 coreboards. But if you consider that, please open the unit before buying something to make sure that it fits.

Question ID FYT HU by appearance? Antutu #?

Is it possible to ID an FYT UIS7862 by appearance?
Just wondering if this is an FYT unit (the 3G and higher). https://www.aliexpress.com/item/10000399588630.html
Will the difference between 3G and 4G RAM be noticeable?
Also gadgetversus says antutu benchmark # is 87k, but I saw an aliexpress ad (didn't make note of where) that says UIS7862 benchmarks 181k. Which is correct?

Those do look like FYT units as described by the seller.
get 4G RAM for future proofing, also because you double the storage to 64GB (for more apps).
I wouldn't trust AliExpress ads as far as I can ship them (from China).

I am not sure whether this is a FYT. Some screens lok like it. Others not at all.
Ask the reseller

I responded based on this chart:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}

According to seller, they are.
I don't really think I'll need a lot of apps on it. Probably just a navigation app (was thinking Google Maps) and alternate music app if the built-in one doesn't have any nice visualizations. I just don't want it to feel laggy and sluggish. I don't drive but maybe 500-miles a year since I work from home and have reserved a new vehicle, so I don't feel like I need anything really nice since this is just to tide me over (which might be a year or two).
How would a UIS7862 with 3GB RAM compare to a PX6 with 4GB? They're close in price.

Ask for screenshots of system information and MCU type

Good idea. The seller sent me a screenshot that shows it's definitely FYT, but it's the 9" or 10" version. I'm actually interested in the 7" version.
