Reviews

Already Saved me a ticket.

"Less than a week after purchasing, this unit saved me from a ticket. Highly recommended. Also got the hardwire kit, that's definitely a must have if you want a neat professional looking rig. 5 Stars"

— Jeff N. (5/5)

Waste of money

"Item doesn't work with 490i radar detector. Had it installed by Best Buys and it doesn't power up the radar. This was a complete waste of time and money (purchase and installation cost plus time it took for them to tell me it doesn't work). Very disappointed."

— Todd P. (1/5)

Hard wire

"Worked great cut the pins off and put tap a fuses on no issues"

— Billy p. (5/5)

Does not work as is should

"I have been back-and-forth with Cobra since October 2025. The camera will shut off while driving after the auto-shutoff timer is reached,. (Easy enough to test, set the auto shutoff to 1 hour, and after 1 hour while driving the camera shuts off). Then, the camera will not turn on when the car is started - you have to either manually press the ON button, or disconnect and reconnect the power supply. Yes, all wires are properly connected. Cobra knows there is a problem, the red ACC wire should control camera operation. The hardware kit has been replaced. The camera was replaced. No improvement. This was supposed to have been escalated , but still no answer."

Makes for an easy installation

"Easy Installation with everything needed"

— John S. (5/5)

Install instructions are vage

"Ordered these for new truck that did not have cig lighter, the instructions say if you want to have switched power and then nothing on how to wire this. Wiring it per the tags powers the system constantly which will drain your battery."

— ERIC K. (3/5)
