Yes, the REXING C4 does record audio from the main device. That being said, it will record what is in the car as you hear it and will only record what it can hear outside through the windows if they are open. This can be turned off in the settings if you want it not to record audio. If you need help or have another question, please email our REXING support team at care@rexingusa.com. They will be quick to respond in as much detail as needed.

To remove the memory card from your REXING C4 dash cam, ensure the camera is fully powered down first to prevent data corruption. Gently press the exposed edge of the card inward using your fingernail or a small tool until you hear a click, then release it so the spring-loaded mechanism can pop it out. If you run into any issues during this process or need further technical assistance, please email our support team directly at care@rexingusa.com for help.

Yes, the REXING C4 dash cam will work perfectly fine in a 2026 BMW 330i. To ensure a clear recording angle, mount the unit slightly to the passenger side so the large camera housing behind the BMW's rearview mirror doesn't block the lenses. If you run into any issues during setup or need help routing the wires cleanly, please feel free to email our support team at care@rexingusa.com.

The REXING C4 4-Channel Dash Cam is fully compatible and will easily fit into a 2020 Nissan Altima. The universal windshield mount allows for clean placement just below your rearview mirror, and the wiring can be tucked directly into the surrounding interior trim panels. If you need any further assistance with your installation or setup, please feel free to email Rexing Support directly at care@rexingusa.com.
