Motorola PMHN4429A Side Connector Dust Cover for MOTOTRBO R7
Genuine OEM mini-GCAI port protector for MOTOTRBO R7, Ion, MXP600, and APX Next-generation portables.
The Motorola PMHN4429A is a genuine OEM side connector dust cover designed to protect the mini-GCAI accessory port on MOTOTRBO R7, Ion, MXP600, and APX Next-generation portable radios. When audio accessories such as remote speaker microphones or surveillance earpieces are disconnected, the exposed port is vulnerable to dust, moisture, and debris. The PMHN4429A snaps directly into the side recess of the radio housing — no tools required — keeping contacts clean and corrosion-free between accessory swaps. The PMHN4429A is the updated version of the Motorola PMHN4429.
