The GM160 programming software ONLY communicates via true hardware COM ports (COM1, COM2, etc.). It does not recognize USB-to-Serial adapters natively.
The software was designed for the Windows 95/98/XP era.
The Motorola GM160 is a workhorse of the commercial radio world. Known for its rugged durability and simple front-panel interface, it was a staple in taxis, delivery fleets, and construction sites. However, programming one today is not as simple as plugging in a USB cable. Because this is a legacy radio, it requires specific legacy software and hardware interfaces. This guide covers everything you need to know to get your GM160 on the air.
The specific software required for the GM160 is listed in Motorola’s internal documentation as "Professional Series RSS" version R06.12.05 or R06.12.07. Some users also report success with RVN4174 or RVN4175 (the part numbers for the programming kits). motorola gm160 programming software
A note on "Windows" versions: There is no native 64-bit Windows 10 application for the GM160. If a website offers an ".exe" file that claims to be "GM160 Software for Windows 10" without requiring a DOS box or virtual machine, it is likely a virus or a ripper tool for codeplugs. Be extremely cautious.
Some advanced users build an EEPROM reader (via I2C) to read the 24C64 EEP chip inside the GM160 directly. This bypasses the RSS entirely, but it requires soldering and hex editing skills.
The Motorola GM160 programming software is a relic of the 1990s engineering philosophy—powerful, but user-hostile. While modern radios have moved to USB and slick CPS, the GM160 remains a tank that refuses to die. By embracing DOSBox, vintage serial ports, and a little patience, you can breathe new life into these classic radios. The GM160 programming software ONLY communicates via true
Warning: Always read the existing codeplug before writing. If you upload a corrupted codeplug, you can brick the radio. Once the EEPROM is scrambled, you will need a hardware programmer to unbrick it. Backup your original codeplug file (usually using the RSS F5 Save function) to a floppy disk or emulated drive.
If you lack the time or technical inclination, sell your GM160 on eBay and buy a modern Baofeng or AnyTone. But if you want to master a piece of Motorola history—get the RIB, fire up DOSBox, and enjoy the green glow of the RSS interface.
