Magnetic Mic works with virtually all radio systems. It doesn’t matter if your radio system functions with an on-hook/ off-hook setting, switches to a private line or scans when hung up—it’s ready for use with your radio system. Magnetic Mic replaces a traditional microphone hang up clip using the standard 2-hole mount the OEM versions use. The Magnetic Mic design helps the user stay focused on keeping their eyes on the road. It can be used with any manufacturer's mobile microphone. Just get it close and let it go!
