Simply mount the control box with velcro near your mobile radio. Plug the hand mic into the control box and the other curly cord back into the mobile radio. The visor mic can be mounted on the visor or A pillar. The foot pedal gets mounted over on the far left upper side of the driver's floorboard. No vehicle or radio wiring is involved. A very easy, straightforward DIY installation with the included instructions. No bluetooth connectivity problems. No lag time. This is a great, affordable solution that makes communicating on the 2-way radio much safer and easier! We have kept our overhead low in order to pass the savings on to our customers. As a retired police sergeant, I wanted to make at least one aspect of police work a little bit safer. We appreciate your business and hope you stay in touch for updates and more products!
