Initial assessment of available information • You supplied a photo of the “About / Version” page of a generic single-DIN/2-DIN car multimedia unit. • Version string shown on the display: – System: V7.52BT-FK-TP – Board (main application CPU) code: ZCD-7089-6905C-IC – MCU: V04.31 --- dated 2019-11-27 13 : 46 : 57 – Bluetooth name: CAR-KIT, PIN 0000
Your request (Arabic): «أريد تحديث أو إصدار أحدث من هذا» – “I want a newer firmware / update for this unit.”
No brand name is visible, which is typical for “no-name” or “universal” Chinese car players sold under many labels. Because there is no single official support site, the correct firmware must be chosen strictly according to the mainboard ID and the screen resolution; installing the wrong file usually bricks the unit.
-------------------------------------------------------------------- Direct answer to the question 1. There is no single ‘official’ public repository for V7.52BT-FK-TP / ZCD-7089-6905C-IC firmware. 2. Newer packs do exist (V7.67, V7.70 … MCU V04.46, V04.56) but they are distributed only through: • The original seller / AliExpress store where the radio was purchased. • User communities (mainly 4PDA.ru, XDA and several Telegram groups). 3. To obtain and install the update safely you must: • Identify the *exact* PCB model (photo of the naked board). • Confirm LCD resolution (800 × 480, 1024 × 600, etc.). • Backup the present firmware (if the “export update” menu is available) before flashing. • Load both the “APP” file (sometimes named *.BIN, *.UPD, update.img) and the matched “MCU” file. • Flash via the recommended medium (usually µSD card in the GPS slot or a USB pendrive) with ignition ON and engine idling to avoid undervoltage.
Without that information I cannot give you a direct download link, because using a file that was built for another board revision (e.g. 7089-6905C vs 7089-6905A) will kill the touch panel or put the unit in a black-screen state.
-------------------------------------------------------------------- Detailed problem analysis 1. Hardware families • ZCD-7089-xxxx is a very common SPMP800/T3/T5 “Sunplus-T3” platform (not Android, it is a bare-metal multimedia SoC). • The “MCU” in these units is a small STM8/STM32 that handles buttons, CAN steering-wheel keys, illumination, etc. Application firmware (APP) and MCU firmware are independent but must remain compatible.
2. Version scheme • V7.xx = application firmware generation for 800 × 480 screens. V9.xx is typically the same code re-compiled for 1024 × 600. • FK, TP, TF suffixes indicate button layout and touch-panel controller type. • MCU V04.31 was released late 2019. Latest I have seen for this PCB is V04.56 (2021-03). Changes: improved CAN mapping, bug-fix in radio RDS, added Arabic OSD fonts.
3. Boot / update mechanism • On power-up the boot-loader checks for a file named *7089.bin* or *update.img* (depends on version) on the TF/SD root. • If present and the CRC header matches the motherboard code it rewrites SPI-NOR FLASH (about 4 MiB) then restarts. • MCU update is a second step from the system menu: Settings → MCU Update → select *.bin on USB.
-------------------------------------------------------------------- Current information and trends • V7.70 (2023-Q1) is the newest package leaked publicly. It fixes Bluetooth echo and adds FLAC playback. • A small number of vendors already ship V7.80 β (2024-07). At the moment only Chinese language, no public dump available. • Aftermarket community is slowly replacing the closed Sunplus SDK with open FreeRTOS-based builds; still experimental.
-------------------------------------------------------------------- Practical guidelines (step-by-step) 1. Remove the front frame, take clear photos of both sides of the PCB. Post them here or compare PCB silkscreen with those in 4PDA thread “Sunplus 8202/8205 Car MP5”. 2. Record: – LCD flat-cable part-number (to confirm resolution) – Flash IC marking (usually GD25Q32 or 64 Mb) 3. Ask your seller for “latest 7089-6905C firmware English/Arabic”. Most respond within 48 h with a Google-Drive link. 4. Verify the ZIP contains *both* APP and MCU folders and that the first 16 bytes of APP *.bin* start with ASCII “7089-6905C-IC”. 5. Copy files to a freshly FAT32-formatted 8 GB µSD, insert in GPS slot, turn ACC on, wait ~4 minutes, unit reboots automatically. 6. Enter Settings → Factory (code 1617) → Version to confirm new numbers. 7. Immediately calibrate touch if prompted and restore personal settings.
-------------------------------------------------------------------- Safety, legal and ethical aspects • Firmware is copyrighted by the original OEM; public mirrors are legally grey. Use only files obtained from the hardware vendor or backed-up from the same model. • During flashing keep battery voltage > 12 V (engine on) to prevent brown-out. A failed flash may require an SPI programmer + SOIC-8 clip to recover.
-------------------------------------------------------------------- Suggestions for further research / information sources 1. 4PDA.ru forum → Раздел “MP5 на Sunplus” → Thread “T3L/T5L V7.x firmware collection”. 2. Telegram channel “china-car-mp5-firmware”. 3. YouTube: search “sunplus T3 firmware update 7089” for video walkthroughs. 4. If you have access to an SPI-NOR programmer, back up the entire 4 MiB before any experiment.
-------------------------------------------------------------------- Brief summary A newer firmware for your ZCD-7089-6905C-IC unit exists (V7.67 / MCU V04.56 and newer). To avoid bricking, match the update precisely to the PCB and screen resolution, obtain both APP and MCU files from the seller or specialised forums, and follow the SD-card flashing procedure with stable 12 V supply.
-------------------------------------------------------------------- Questions for you 1. Can you provide a photo of the mainboard to confirm the exact revision? 2. What is the LCD resolution of your unit (look in Settings → Display or measure screenshot)? 3. Do you have access to the original shop / supplier who might already hold the correct update files?
