Applies to: CHIGEE Display models with dashcam/storage (e.g., AIO-6, AIO-5 Lite)
Card type: microSD/TF
1) Check SD Card Specifications (Most Common Cause)
Capacity: ≤ 256 GB supported. 512 GB (and larger) are not supported.
Speed class: Use U3 / A2 / V30 (high-endurance video cards preferred).
Guide: How to Choose the Right Memory Card for Your Motorcycle Dash Cam (pick reputable brands; avoid “too-cheap” high-capacity cards).
2) Verify SD Card Installation
Improper seating often triggers format errors.
Power off the display.
Remove the card, then reinsert firmly until it clicks.
Power on and check if the message clears.
3) Format the Card (Recommended Order)
On the CHIGEE Display (preferred):
Settings → Storage/SD Card → Format.
If device format fails, use a computer:
Use the SD Association Memory Card Formatter (Quick Format; if needed, Overwrite Format).
Reinsert into the CHIGEE Display and format again on the device.
If the card reports odd capacity or can’t complete an overwrite format, it’s likely defective/counterfeit—replace it.
4) Try a Factory Reset (if errors persist)
CHIGEE Display Settings → Reset → confirm.
Then repeat the format steps above with a known-good ≤256 GB U3/A2/V30 card.
Extra Checks
Adapter lock: If using a microSD→SD adapter on PC, ensure the lock switch isn’t set.
File I/O test: Copy a 2–4 GB video to the card on a PC and play it back; corruption = bad card.
Slot/contacts: Inspect for debris or bent pins (no metal tools).
Avoid exotic setups: Single partition, standard filesystem only; let the device do the final format.
Known Unsupported / Not Recommended
512 GB+ cards
Low-speed cards (Class 10/U1 or unmarked)
Counterfeit/remarked media
