Frequently Asked Questions

Garmin Dash Cam asks to format SD card every time it starts — cause?

Repeated format requests indicate the card is failing and losing its file system between sessions. Replace the SD card — this is a sign of imminent card failure.

Garmin Dash Cam 57 not detecting brand new SD card — what to check?

Format the new card in the Garmin camera immediately (a new card may be formatted for a different device). Confirm the card is a microSD (not a full-size SD) and that it is a U3-rated card.

Can I use a Garmin-branded SD card in another dash cam?

Yes, Garmin SD cards are standard microSD cards. However, each camera formats cards differently — always format the card in whichever camera you are using it in to avoid compatibility errors.
