: The Motorola GM950 Plus RSS (Radio Service Software). Note that standard GM950 software often fails to read "Plus" models; you specifically need the version that supports the Plus series.
However, the GM950 Plus is a legacy radio. It is considered "End of Life" (EOL) by Motorola. While official support channels have moved on, the software (often version 06.xx or earlier) is widely available in the amateur radio community and through various repositories of legacy software. motorola gm950 plus programming software top
