It can be done via the small lock button on the screen. **Q: Where do i put the red cable that is attached to the camera end of the reverse camera? Its just a wire with no attachment on the end** A: Thanks for contacting. You can connect the red wire of the rear cable to the positive pole of your car's reversing light, then it will show reversing line when you reverse. You can leave the red wire there if your car ahs its own reversing system Hope my answer is useful to you. If there is anything we can help with, please let us know. Have a nice day! Wolfbox **Q: Made in China?** A: Yes I believe it is. My auto electrician thought the cameras were high quality. **Q: Is there an option to mount this without using the rubber bands - to use the existing rear mirror mount instead and remove the existing mirror??** A: Hi,It's better not. Our mirror dash cam doesn't have a bracket and needs to be fixed with rubber straps. Thank you. ## Frequently Bought Together - WOLFBOX G840S 12" 4K Mirror Dash Cam Backup Camera, 5.8GHz WiFi Smart Rearview Mirror for Cars & Trucks, Front and Rear View Dual Cameras, Night Vision, Parking Assistance, Included 32GB Card & GPS - WOLFBOX USB C Hardwire Kit for G850PRO/G840S/G930/G850/G900/G840H/i07/i17/X5 Mirror Dash Cam, not Suitable for G890/G900 PRO/G900 Tripro, Parking Monitor with Multiple Size connectors - WOLFBOX OEM Bracket for USB C G900 Tripro/G900PRO/G850PRO/G840S/G840H/G850/G900 Mirror Dash cam --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nl/products/201966142-wolfbox-g840s-12-4k-mirror-dash-cam-with-5-8ghz](https://www.desertcart.nl/products/201966142-wolfbox-g840s-12-4k-mirror-dash-cam-with-5-8ghz) --- *Product available on Desertcart Netherlands* *Store origin: NL* *Last updated: 2026-09-09*
