Garmin Dash Cam 35 Does Not Power On

If your Garmin Dash Cam 35 isn’t turning on, even when plugged in, follow this page for possible solutions.

The mini-USB cable or car charger may have internal wire damage or a poor connection.

• Plug the dash cam into a different vehicle power outlet or a USB power supply rated for at least 1A output. Confirm the outlet works by testing it with another device.
• Use a different mini-USB cable and a known-good charger. Garmin cables are prone to internal breakage near the plug ends.

Dust, corrosion, or bent connector pins can block electrical contact.

• Remove any debris or corrosion from the dash cam’s mini-USB port using a soft brush or compressed air. Check that pins are straight and not bent.

The internal lithium-ion battery may no longer hold charge.

• Hold down the Power button for 10 seconds. If there’s no response, disconnect power, wait 1 minute, then reconnect.

The fuse inside the 12V plug or the vehicle fuse box may be blown.

• Unscrew the tip of the 12V charger plug and inspect the small fuse. Replace if burnt or broken. Also, check the vehicle’s accessory fuse.

The dash cam firmware could be frozen or unresponsive.

• If the device still does not power on, replace the internal 3.7V BL-5B lithium-ion battery.
