@Ken226 Do you still have the 2013 Canadian RA4 VP4-CA v17.43.01 fw you used to update your radio via usb (prior to v18.45.01) that you can upload/share for others? (I will link it to post 7. ) ** I also need to search and see if someone had the 2017 Canadian RA4 VP4-CA v17.xx.x file? @bloup , do you still have it? . M² Mods.
