This document provides installation instructions and usage information for a GPS Dual Dash Cam, specifically the CHORTAU B-T25 model.

Function Description:

The CHORTAU B-T25 is a dual dash cam system designed to record both front and rear views of a vehicle, with integrated GPS functionality to track the vehicle's path. It supports continuous recording and can display the recorded video with GPS data, including vehicle location on a map and speed. The system offers a reverse function, allowing the display screen to switch to a full-screen rear view when the car is in reverse, provided the car does not have a built-in reverse system monitor. If the car already has a reverse system monitor, the dash cam will record the rear view while driving and display a picture-in-picture view of both front and rear cameras.

Important Technical Specifications:

Front Camera: 170° Wide Angle Lens, 12.0 Mega Pixel, F1.8 aperture.
Video Resolution: 1080FHD (as indicated on the display).
GPS Module: Designed to be placed close to the windshield top for better signal reception.
Storage: Requires a 32GB, Class 10 micro SD card.
Power: The dash cam requires continuous power supply.
Display: The dash cam features a display screen for viewing recordings and settings.
GPS Data: Records GPS path, speed (KM/H), and can display vehicle location on Google Maps.
Player Software: GXPlayer is recommended for viewing video with GPS path data. VLC media player can be used for normal video viewing.

Usage Features:

Installation:
- Front Camera: Connects to the car charger, with the cable hidden into the interior panel. The GPS module should be stuck near the windshield top.
- Rear Camera: Can be installed either inside or outside the car, typically above the license plate. The rear camera cable can be routed in two ways (illustrated in the manual).
- Reverse Function (Situation 1 - No built-in reverse system): The red wire of the rear cam cable must be connected to the car's reversing lamp positive terminal. When reversing, the dash cam display switches to full-screen rear view.
- Reverse Function (Situation 2 - Built-in reverse system): The red wire of the rear cam cable does not need to be connected. The dash cam will record rear view and display a picture-in-picture view of front and rear cameras while driving forward or in reverse.
Initial Setup:
- Insert a 32GB, Class 10 micro SD card (poke it deeply until it clicks).
- Charge the dash cam for 2-3 hours.
- Power on the camera and format the SD card.
- Select the local time zone in settings (e.g., UTC + 8:00 for East US, UTC - 5:00 for West US, UTC + 7:00 for Middle US).
GPS Connectivity: GPS connects automatically within a few minutes after the dash cam starts. The GPS sign on the display changes color to indicate status: red (disconnected), yellow (connecting), green (connected).
Viewing Video:
- On Dash Cam: Stop recording, then press the M button to enter playback mode. Use up/down buttons to select front video. Long press the down button to enter rear cam playback. MOV files are front camera videos, AVI files are rear camera videos. A lock icon indicates a locked video.
- On Computer (with GPS data):
  1. Insert the SD card into a card reader and connect to a computer.
  2. Locate the "DCIM" folder (contains recorded videos: "Fold 1" for front, "Fold 2" for rear).
  3. Install GXPlayer (by clicking "gpsplayer" file on the SD card).
  4. Open GXPlayer and navigate to the video files on the SD card.
  5. GXPlayer displays the video, vehicle location on Google Map, speed, and GPS path. Users can switch to satellite mode.
  6. Settings within GXPlayer allow changing language, speed unit, or maps.
Settings: Click the middle button of the screen to enter the video setting page. Click twice to enter the system setting page.
Parking Mode: Long pressing the down button can turn on/off parking mode.

Maintenance Features:

SD Card Management:
- Format the SD card monthly to extend its lifespan and prevent "card full" errors, especially if G-sensor and parking mode are enabled (which can create many locked files).
- If the camera says "please insert a C6 card," ensure a high-speed, good-quality card is used, or turn off the camera before inserting the card.
Troubleshooting:
- Camera not turning on:
  1. Check for continuous power supply.
  2. Connect power supply and click the reset button.
  3. Ensure the SD card is not defective; try removing or replacing it.
- Dash cam keeps on and off: Ensure the power cord cigar lighter car charger is tightly connected and providing continuous power. If the issue persists, the charger might be defective and needs replacement.
- Rear cam not working:
  1. Check all wire connections for tightness.
  2. If the rear cam or wire is defective, contact support for a replacement.
- Time setting not saving: Select your local time zone during initial setup. The camera will automatically switch to the local time zone each time the car starts.
