V2 Update

Motorcycle Audio – V2 Headunit Firmware Update (June 2024)

WARNING: Before attempting this update, please read these instructions carefully and don’t skip any steps, and be sure to use a blank flash drive (FAT32 format) from a reputable brand (SanDisk, Samsung, etc). If the flash drive is not empty, be sure to format it. You can find instructions on how to format a flash drive HERE.

A minimum 4GB or larger USB Type-A flash drive with USB 2.0 or 3.0 is required. Using a flash drive with unknown USB specification will diminish data transfer and can corrupt the system processors. Use reliable name-brand USB flash drives. We use and recommend SanDisk Cruzer.

  2. Save ISPBOOT.BIN to the root of a blank USB Type-A flash/thumb drive.
