I have a band new Inspire 1 and need to update the firmware. I have looked at the instructions in the user manual, and as simple as they seem, I don't fully understand. I've downloaded the WM610_FW_V01.05.00.30.bin file to my computer. The instructions say to extract the files to the SD card. When I double click the .bin file, it create a single .bin.cpgz file. This doesn't seem right. I'm working on a Mac. Some somebody point me in the right direction?
