Initial assessment of what you have and what you’re asking
From your posts (2022-08-09 → 2025-01-22) you have head units labeled “CAR‑KIT” with:
- MCU V129.18 and V129.49
- Software strings like zcd‑7106‑6925‑apk‑0825 and ZCD7106‑6925‑V2.0 (dates around 2020–2022)
- You want: a source (“official website”), a safe update method, and a way to enable a “logo” function (boot logo).

The key identifier is “ZCD7106‑6925”. In practice, this maps to an unbranded 2‑DIN platform whose mainboard is marked ZCD7106‑C200S‑MAIN and uses an Allwinner F1C200S application SoC. These units are not Android; they run a lightweight vendor UI on top of a small RTOS/Linux stack inside an 8‑MB SPI flash. That is why you won’t find a single official site; firmware circulates only via community/repair forums and seller shares. (test.remont-aud.net)

Direct answers to your three recurring questions
- Official website and “latest” files: there is no public, manufacturer‑run portal for the ZCD7106‑6925 platform. Dumps/updates appear on repair forums under the board code ZCD7106‑C200S‑MAIN (various revisions V1.x–V2.x) and as version tags like ZCD7106‑6925‑V2.0 (2021‑10‑16). Treat all such files as hardware‑specific. (remont-aud.net)
- How to update: there are two distinct pieces of code and two update paths:
1) The “main system” image in the SPI NOR (25Q64…), updated either from an “update.img” package (if your UI exposes an updater) or by external programming of the SPI flash when bricked. (repairalltv.com)
2) The small “MCU” firmware (the V129.xx string) that handles radio/SWC; this is separate from the main image and, on some variants, can be updated from a factory menu. Cross‑flashing between close V129 builds can still break radio/touch due to board differences—don’t do it without a board‑exact match. (reddit.com)
- Logo function: it is normally in the factory menu. On ZCD7106‑C200S units the common password is 1617. From there select Boot/Car Logo (preloaded logos). Some firmwares also accept a custom image but only if the resolution matches your panel. (test.remont-aud.net)

Detailed technical analysis (what these numbers really mean)
- Hardware identity
- Board family: ZCD7106‑C200S‑MAIN V1.x/V2.x, seen in many “7012B/7018B” style players. Main SoC: Allwinner F1C200S (ARM9 with 64 MB SIP DDR). This silicon targets embedded RTOS/Linux (Melis/Linux SDK), not Android. (test.remont-aud.net)
- Software string: “ZCD7106‑6925‑V2.0” is a vendor bundle name that must match your board, LCD and touch controller. One widely circulated build is dated 2021‑10‑16; newer “universal” images are not published by an OEM. (remont-aud.net)
- Storage: 8‑MB SPI‑NOR (e.g., EN25QH64/25QH64CH). Service sites share full 8‑MB dumps for ZCD7106‑C200S‑MAIN V2.x. (repairalltv.com)
- Why “Android conversion” is not feasible
- F1C200S lacks the RAM/graphics stack and Android BSP that Android head units use (those are typically Allwinner T3/T5, Rockchip, or UIS7862). Your firmware, drivers and storage layout are entirely different; replacing software cannot turn it into Android. The practical “upgrade” path is replacing the unit or the entire mainboard with an Android board made for your fascia and harness. (wiki-power.com)
- About MCU V129.xx
- The “V129.xx” string is an MCU branch used across multiple white‑label head units (Android and non‑Android). Names and file formats are not interchangeable across boards—even if “V129.xx” matches—because tuner, dimming and key‑scan tables differ. Users who mix MCU or system images across similar boards commonly end up with “white screen”, dead touch or muted radio until they restore the exact original dump. (reddit.com)

Current information and trends (as of Nov 20, 2025)
- Community archives still center on board‑exact SPI dumps for ZCD7106‑C200S‑MAIN; ZCD7106‑6925‑V2.0 is among the newest broadly shared tags. No OEM “OTA” or global release channel has emerged for this platform. (remont-aud.net)
- Many sellers have moved to newer, different hardware (e.g., Allwinner T3‑P1 or Android‑Go boards) sold under similar product names; files for those will not work on ZCD7106‑C200S. Check the silkscreen on the PCB before using anything. (remont-aud.net)

Practical, step‑by‑step guidelines
1) Positively identify your hardware
- Pull the unit and photograph the PCB near the LCD ribbon: look for “ZCD7106‑C200S‑MAIN‑Vx.y” and note the LCD panel/touch IC codes. Also read the SPI chip marking (e.g., 25Q64). Post those photos here. This is the only safe way to match an image. (test.remont-aud.net)
2) Back up before you do anything
- If your UI has no reliable “system update”, make a byte‑for‑byte backup of the SPI NOR using a CH341A/TL866 programmer and a SOIC‑8 clip. Verify the read twice and keep the hash. If you ever need to revert, you can rewrite that dump. (repairalltv.com)
3) If your firmware supports an in‑place update
- Prepare a small FAT32 USB/SD. Put only the vendor’s update package (often named update.img) on it. Power the unit from a stable 12–14 V source (engine running or bench PSU ≥2 A). Start the updater from Settings → System/Factory → Update. If no update menu exists or the process refuses the file, do not force it—use the programmer method instead. (reddit.com)
4) If you must reflash externally
- Program the exact matching dump for your board revision (same “ZCD7106‑C200S‑MAIN‑Vx.y”, same LCD/touch/tuner). After writing, verify, then reassemble and test radio, touch, keys and reverse camera. This is the standard service workflow documented by repair sites for these units. (repairalltv.com)
5) Boot logo feature
- Enter Factory settings (password 1617). Open Boot/Car Logo and pick a preset. If “Custom logo” exists, use an image that exactly matches your screen’s native resolution (commonly 800×480 or 1024×600 on these units) to avoid scaling artifacts. Do not change unrelated factory items. (manuals.plus)

Supporting notes, risks and safety
- Mismatched images (even within ZCD7106) can yield a white/garbled LCD, dead touch or no audio; recovery then requires SPI programming. Keep a verified backup. (remont-aud.net)
- Many update files found online are raw dumps; they do not contain a universal installer. Expect that you may need a programmer if the on‑device updater is absent. (repairalltv.com)
- Stable power is critical; voltage dips during updates brick these units. (reddit.com)

Ethical and legal aspects
Firmware images are copyrighted by the original ODMs; community sites share board backups for repair. Use them only for your own hardware and keep local copies, as links frequently disappear. (remont-aud.net)

What I recommend for you now
- If everything works and you only want a boot logo: use Factory password 1617 and change the logo there—no firmware update needed. (manuals.plus)
- If you still want to update:
- Provide clear photos of the PCB silkscreen (ZCD7106‑C200S‑MAIN‑V?.?), LCD FPC label, and the About/Version screen. I will help you match a safe image for exactly your board and resolution. (test.remont-aud.net)
- If you want “full Android”: it cannot be achieved by software on this platform; consider replacing the head unit/mainboard with an Android model that fits your fascia and wiring.

Suggestions for further research (curated, relevant threads/archives)
- Elektroda topic you’re posting in (keeps the history and photos you attach). (elektroda.com)
- Remont‑aud board archives for ZCD7106‑C200S (multiple board revisions; requires registration to download). (remont-aud.net)
- Example listing confirming ZCD7106‑6925‑V2.0 tag and hardware family. (remont-aud.net)

Brief summary
- Your “ZCD7106‑6925 / MCU V129.xx” unit is a non‑Android, Allwinner F1C200S platform with firmware stored in an 8‑MB SPI flash. There is no single official website; updates are board‑specific and risky. The boot logo is available via the factory menu (password 1617). Update only with a board‑exact file—and only after you make a SPI backup—otherwise you risk a brick. (test.remont-aud.net)

Questions for you (so I can locate a safe image or record a short video for your exact unit)
1) What is the exact PCB marking near the LCD connector (e.g., ZCD7106‑C200S‑MAIN‑V2.0/V2.2)? Clear photo, please. (test.remont-aud.net)
2) What is your LCD resolution in the About screen (800×480 or 1024×600)?
3) Do you see a System Update or MCU Update entry in Settings/Factory? If yes, what filenames does it accept?
4) Are you looking only for the logo function, or do you have a functional problem you hope an update will solve (e.g., radio RDS, touch misalignment)?

If you share these, I’ll give you a tailored update checklist and, if appropriate, point you to a board‑exact package and a short how‑to video for your variant.
