Frequently Asked Questions - MR155 NV Navitel

How do I install the Navitel MR155 NV dash cam?

Mount the device on your car mirror using the clamps. Insert a microSD card (Class 10 or higher, 8-64 GB) and format it in the DVR. Connect the car charger to the cigarette lighter and mini-USB port. Adjust the camera position. The device will start automatically when the engine starts.

Why do I need to format the SD card in the DVR?

Formatting prepares the card for optimal performance and prevents data errors. Always format a new SD card or one with errors using the 'Format SD-card' option in the menu.

What is loop recording and how does it work?

Loop recording splits video into segments of a set duration. When the card is full, the oldest unprotected files are overwritten. This ensures continuous recording without manual intervention.

How does the G-sensor protect my videos?

The G-sensor detects sudden impacts or collisions and automatically locks the current recording file so it cannot be deleted or overwritten during loop recording.

What is the parking monitor feature?

When the DVR is powered off, the parking monitor uses vibration detection. If vibration is sensed, the device turns on, records a protected video, and then shuts down after one minute if no further activity.

Can I use a rear camera with this DVR?

Yes, the MR155 NV supports a rear camera (sold separately). When connected and reverse gear is engaged, it displays the rear view with parking lines. You can also switch between front and rear views.

How long does the battery last?

The built-in 180 mAh battery is designed only for short-term emergency recording (e.g., parking mode) and proper shutdown. For full operation, constant power from the car charger is required.

How do I protect a recording from being deleted?

While recording, press the Menu button to lock the current file. A key icon appears. Locked files are protected from deletion or overwriting.

What should I do if the device freezes?

Press the Reset button (using a pin) to restart the DVR. If the issue persists, try formatting the SD card or contacting support.

Is the Navitel MR155 NV available in multiple languages?

Yes, it supports 17 languages including English, French, German, Spanish, Russian, Chinese, and more. You can change the language in the settings menu.
