Tank you for your help !

This is possible to remove the SD card in the radio, copie the update file and reinstall the sd card into unit ?

Did you place the usb flash drive in USB1? If you have an SD card you can also run the update from that too

Did you ever figure out a solution. Im having a very similar issue
