Thanks everyone who put this together and provided instructions! I recently bought a car with a z110bt installed but never upgraded and you made this a fast and easy upgrade.
I installed the shortfuse crack on update 1.001 and stuck in the SD card and it updated. Then I copied the SD1 folder from CSND-210 onto the sd-card, stuck it back in and it updated again. With that card still in I updated the bluetooth firmware. Then I put the contents of the SD2 folder on and updated the bluetooth firmware again.
