Firmware Upgrade
12. Upgrading Firmware
As with most modern electronics devices, the internal control system of this radio uses a
powerful microcomputer and associated software or firmware. It may be necessary to add
new firmware to the radio to ensure best levels of performance. The new firmware can be
uploaded into the radio using a USB storage device. The upgrading process is simple but
some precautions must be taken to ensure successful results. Please read the following
instructions and notes carefully before attempting a firmware upgrade.
Contact your dealer for details of how to obtain new firmware upgrade files.
Three types of firmware upgrade files are used:
CPU firmware (CD/USB/iPod) e.g. file name:
CNC_TECH_Vxxx.cpu
MCU firmware (RADIO/AUX) e.g. file name:
CNC_TECH_Vxxx.mcu
Bluetooth firmware e.g. file name:
CNC_TECH_Vxxx.dfu
