Motorola Gm950 Programming Software Top May 2026

Navigate to the "Conventional Personality" menu.

Repeat for up to 64 channels.

There is no Windows CPS for the GM950. That model was discontinued before Motorola switched to Windows-based Customer Programming Software (CPS). The GM950 is strictly DOS RSS.

If you want a modern programming experience, consider upgrading to a GM338 / GM3188 or PM400 (uses Windows CPS). motorola gm950 programming software top

It is important to clarify the correct terminology for the software used with the GM950 series.

Do not use cheap Chinese USB cables claiming to be "FTDI for GM950." They cause endless driver issues, timeouts, and checksum errors. For guaranteed success:

Pro tip: The GM950 is slow to program (baud rate 9600). If you get "Communication Error," slow down your PC’s CPU emulation or use DOSBox with appropriate cycle settings. Navigate to the "Conventional Personality" menu

Open the RSS/CPS. You will see a blue or grey Motorola splash screen.

Assuming you have identified your radio model, sourced the software, and assembled a working RIB + cable, here is the workflow.

You press F3 to read the radio... and you’re hit with a Password Prompt.

Motorola dealerships could lock radios to prevent theft or unauthorized reprogramming. If the previous owner forgot that password, your GM950 is now a very heavy brick. There is no "reset." There is no "forgot password" link. The only solutions are brute-force hex-editing the codeplug (requires an advanced engineering degree in pain) or desoldering the EEPROM chip to reprogram it externally.
