Question 1

Is the hole saw/drill bit included in the package, and what size hole do I need to drill?**

Accepted Answer

The kit does include a drill bit, but we recommend using a high-quality 25mm (1 inch) hole saw instead, as the included bit is thin and may chip paint on harder bumpers. Many DIY users on YouTube emphasize that the key to a flush fit is drilling from the outside in and deburring the edges. If you are unsure, a universal kit like this fits most steel and plastic bumpers, but you must measure the curvature of your bumper to ensure the sensor housing seats flat.

Question 2

Does this system have a screen, or does it just beep? How loud is the buzzer?**

Accepted Answer

This is an audio-only system (with a buzzer), not a visual display system. It does not include an LCD screen. The buzzer volume is fixed—it is not adjustable. While it is audible inside most cabins, several users have noted that it can be hard to hear over loud music or with the windows down. If you require a visual distance readout, you may want to look for a system with a dashboard screen.

Question 3

I have a tow hitch or bike rack. Will the sensors constantly alert me?**

Accepted Answer

Yes, this is something to be aware of. The system does not have a feature to manually disable individual sensors. If you have a permanently mounted tow hitch or a bike rack, the ultrasonic waves will bounce off your attachment, causing continuous beeping. Most users find this manageable by turning the system off via the power switch when the rack is installed, but it is not a smart system that automatically filters "obstacles" versus "attachments."

Question 4

I'm not very technical. Can I install this myself, or should I pay a professional?**

Accepted Answer

If you are comfortable with basic car wiring (connecting power, ground, and reverse light wire), you can install this in about 1-2 hours. The control box is plug-and-play, and the wiring diagram is generally accurate. However, we warn that the hardest part is the physical drilling and mounting. If you are nervous about cutting holes in your bumper, or if your car is under warranty, we strongly advise having a professional install it. A botched installation will cost more to fix than the price of the unit itself.

Question 5

Will the "Black" color match my car's factory paint?**

Accepted Answer

The housing is a gloss black plastic. It will match most factory black and dark gray bumpers well, but it is not paint-matched. If you have a pearlescent or metallic black, the color difference might be noticeable under direct sunlight. Tip from the community: if the sensors protrude slightly, you can use a black rubber gasket around the housing to make it look more "factory." If you have a non-black car, you will need to have these sensors painted, as the kit only comes in black.
