Motorola Gm950 Programming Software Verified Online

Contact a two-way radio shop. Many will sell you a CD-ROM copy of Commercial Series CPS R06.12.05 for a nominal fee ($50–$100) if you prove you own the radio. This is the only 100% verified, guaranteed-safe method.

Native DB9 RS-232 serial ports work best. If you must use a USB-to-serial adapter, only verified drivers (e.g., FTDI chipset) are acceptable. Many “cheap” adapters introduce timing errors that the GM950’s legacy protocol cannot handle.

Follow these steps precisely. Do not skip the reboot. motorola gm950 programming software verified

Title: Works as intended – but know what you’re getting

Rating: 4/5 Stars

Review:
The software installed without issues on an older Windows XP machine (as expected – don’t try Windows 10/11 without a VM). It reads and writes to the GM950 reliably. The interface is purely functional, no fancy GUI, but it gets the job done for setting squelch, frequencies, and signalling.

Important: This is legacy software, so don’t expect USB plug-and-play. You’ll need a real serial port (or a quality USB-to-serial adapter with Prolific/FTDI chipset) and a compatible RIB box or aftermarket programming cable. Once connected, it’s stable. Verified as working with GM950, GM950 Plus, and GM950i. Contact a two-way radio shop

Tip for buyers: Make sure you get the correct version for your radio’s firmware. This version worked fine on my standard UHF GM950.
