Real Analog RGB output on PDA and fully configurable resolutions (pictures inside)

Hello,
These days I have managed to add real analog video output to my Asus P750. My goal is to connect the pda to my car's navi screen. It has 400x234 res. (NTSC timings).
HARDWARE PART:
I desolder the small LCD FFC connector located on the pda board, and solder ultra fine cable leads to the small pads:

}
Then, I solder this leads to a PCB I have designed months ago with ADV7125 DAC, to make some test before design the final PCB:
This is my car navi screen, it receives analog RGB input:
SOFTWARE PART:
I have built some Windows CE images for PXA270 development platforms, and I have one LCD DLL driver, from Toradex, that is able to make configurable all timings parameters through registry:
http://wiki.toradex.com/index.php/Display_driver_registry_settings
The user of this forum, pupakota (thanks again), helped me. He took the file, and insert it into the Windos mobile 6.1 ROM using something called "kitchen".
Then, I flashed my Asus with the modified rom, leave it to start, and connect to my pc using activesync. With RegEditor, I added the correct config into registry, and new DLL took this config after reset, result? Windows mobile 6.1 400x234 15.7khz 60hz:
(Colors are bad, clock valid edge stuff ... nothing important yet)
BUT, after 10 seconds of the start, it suddenly changes resoluntions and timings to 20.4khz hsync 79Hz vsync:
Please, need software help, what is happening here?? why the SO is "swaping" to another timings 10 seconds after the boot?
Thanks!!!

allright, pm sent, testrom soon. imho, cpu driver's getting into way(it may change lcd timings;/).
check cpu settings on all possible modes(avoid auto).
shame i cannot be there, i think i could help much faster then..

[Q] Which should I order between MK888 and Radxa Rock?

After intensive searches and comparisons I don't know what should I order between:
MK888B / T-R42 which is basically MK888 with bluetooth from AliExpress at 89$ or
Radxa Rock which is build by Tom Cubie, the creator of CubieBoard, with similar specs from MK888B:
SoC – Rockchip RK3188 ARM Cortex-A9 quad core @ 1.6Ghz + Mali-400 MP4 GPU
System Memory – 2GB DDR3 @ 800Mhz
Storage – 8GB Nand Flash + micro-SD SDXC up to 128GB
Video Output – HDMI 1.4 up to [email protected], and AV output
Connectivity:
10/100M Ethernet port
WIFI 150Mbps 802.11b/g/n with antenna
Bluetooth – Bluetooth 4.0
Audio I/O – Audio S/PDIF, headphone jack
USB – 2x USB 2.0 host port, micro USB OTG
Debugging – Serial Console
Misc – IR sensor, power key, recovery key, reset key, 3 LEDs, RTC
Expansions Header -80-pins including GPIO, I2C, SPI, Line in, USB 2.0, PWM, ADC, LCD, GPS… etc
Without the remote control and with a much simple case at 89$.
Both devices are new on the market and don't have a great user base, but their predecessors have (MK888 and CubieBoard)
So, my 89$ question is: which should I buy from this two devices Radxa or MK888?!?

Comparing the pictures of two products, i think it's clear for you which to choose.
Btw, Radxa Rock is an open source project.

What bought?
What have you finally decided? why? are you happy with that?

How to upgrade Android version on head unit? "YT9216BJ"

Hey All.
I just got a head unit for my 2005 Mazda and found out that the actual version is Marshmalllow 6 instead of the advertised 8.1.
Do most head units come with fake 'upgrades'? I used Aida64 app to query list my device (hope accurate).
Is there a way to actually install Android 8.1 on my head unit?[/SIZE][/SIZE]
Unit Info:
YT9216BJ_00012_V001_20200515 <--- build I.D. kernel version (supposedly)
MCU 3.1
Alps AC8227L_demo <--- (not upgradable?)
And... what the heck is 'XY Auto' ?

I had an issue with connecting to my steering wheel control until I went into the Factory Settings to change my CanBus info.
After cycling through different providers and versions I found the 'Raise - 22017 Mazda' works for my 2005 control. (finally says 'connection' instead of 'disconnect")
The only issue I still have is Not being able to connect my stock OEM LCD panel to the head unit, different connection (12-pin vs. 14pin)
Another con I have to get used to: No AM Radio, FM only.
But overall, not too bad for a $130 unit to upgrade my stock radio in my old car.
Now if I can actually get Android 8.1 on it.
Anyone know where I can get latest firmware that'll work for this particular unit ?

Looks like I have the same HU than you in my 2018 Sorento. I'll take a look to see what Aida64 has to say about mine.

Check out this guide to make your unit much better. Faster, better looking and with unlimited tweaking options as well as vast sound improvements.

can anyone know where I can get this update for Android car stereo
update name- "UP_UI19_F27LJ_00011_V001

Hello does this mod or any other fit my radio
