The installation location of the memory card in a dash cam varies depending on the product model: 1. For card-type and screen-less dash cams, the card slot is usually located on the left or right side of the body; 2. For rearview mirror-style dash cams, the card slot is typically found on the upper side of the body. The functions of a dash cam include: 1. Providing decisive evidence for solving cases in incidents of fraud or highway robbery; 2. Preserving valid evidence during accidents, which helps police officers handle situations quickly. A dash cam is an instrument that records images, sounds, and related information during vehicle travel, and its components include: the main unit, speed sensor, and data analysis software.

I remember when I installed the dash cam before, the memory card slot was quite hidden. Most models have it tucked away in a side groove or top recess of the body, usually marked with 'TF' or 'SD' on a spring-loaded slot. Some screen-equipped models even have a guide diagram in the settings menu showing the card slot location – my previous 360-degree cam hid it behind the lens rotation axis. When inserting the card, pay attention to the orientation (don't insert it upside down) – there's usually a small triangle indicator near the slot showing the correct direction. Some newer hidden-style dash cams are even trickier, requiring you to peel open the rubber pad on the base to reveal the card slot. It's recommended to format new cards via the mobile app first to avoid compatibility errors.

I've got experience installing dash cam memory cards. Common locations are on the device body itself - either a slide-in slot on the left side or a push-style socket at the bottom. Rearview mirror-style dash cams are special, with slots often hidden in the gap of the mirror bracket. Last time I helped my dad install his 70mai dash cam, the card slot was right next to the charging port, covered by a dustproof flap that needed to be flipped open. After inserting the card, I recommend recording a few seconds of test footage to prevent missed recordings due to poor slot contact. If the screen still shows 'No memory card' after installation, it's likely either the card isn't fully inserted or the slot's spring plate is stuck.

Dash cam memory card slots vary by model: traditional styles have an opening on the side; rearview mirror types often place it near the mount connection; screenless mini models usually hide it behind the lens. Installation key is identifying the slot type – push-lock slots require an audible 'click' to confirm secure placement. Always power off before inserting cards to prevent short-circuit damage. Choose cards with U1 minimum write speed for smooth loop recording. Older devices may not support cards above 128GB, so verify compatibility before purchase.
