Motorola Gm160 Programming Software ◉

| Problem | Likely Cause | Solution | |--------|--------------|----------| | “Communication refused” | Wrong COM port or radio not in program mode | Some GM160s require ignition sense +12V on pin 10 of accessory connector | | “Codeplug too new/old” | CPS version mismatch | Use R05.16 – earlier versions can’t read newer codeplugs | | Radio powers off after write | Invalid checksum | Re-write with correct frequency range; ensure band limits respected | | Software crashes on launch | Windows 10/11 compatibility | Run in Windows 7 compatibility mode + disable DPI scaling |

The GM160 programming software is powerful but archaic, finicky, and risky. Unless you already have a DOS PC, a RIB interface, and technical patience, pay a professional to program it. If you’re a retro-radio enthusiast, it’s a fun challenge – but expect frustration. motorola gm160 programming software

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 or very early 16/32-bit Windows applications. | Problem | Likely Cause | Solution |
