GeoChron Firmware Flash

I have a GeoChron and am looking to integrate a Blue SMiRF that I have to give me Bluetooth access. SFE is now selling their GeoChron Blue that does this but I bought my units before they started selling the new one. Anyhow, they are providing the Firmware for the Blue unit (which uses the same bluetooth chip as the SMiRF). Does anyone know how to flash the GeoChron’s Firmware? Is it possible to do from the SD card? I’d prefer to not have to buy a specific programmer if I don’t necessarily have to.

No, You have to use Flash magic and Boot Loader
