I have a GM360 Motorola VHF radios that has a code plug error. From what I can gather this is related to corrupted data and that the CPS is too old for the firemware in the radio. How can this happen? Is there an easy fix? I have found a RG45 to USB programming cable on Ebay. What else is required to do the programming? Can a RJ45 to 9pin serial cable work? Do anyone know the pin out required to interface? Where can I get the latest CPS software / firmware for uploading? What software is required to interface with the radio? Sorry for all the questions. Thanks for your help.
