If you have just acquired a used GM160 and need to change frequencies, set up CTCSS tones (PL tones), or reprogram channel spacing, you have likely hit a wall. Modern computers simply will not talk to this radio out of the box. This guide covers everything you need to know about , including where to find it, how to install it on Windows 10/11, necessary hardware, and solutions to common errors. Why Standard Software Won't Work: The DOS Legacy Before downloading anything, it is critical to understand that the GM160 belongs to Motorola’s "Professional Series" (specifically the GM300 series lineage). Unlike the later GM340 or GM360 which used Windows-based CPS (Customer Programming Software), the GM160 is programmed exclusively via DOS-based RSS (Radio Service Software) or very early 16/32-bit Windows applications.
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.

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 have just acquired a used GM160
