Right on the decompress. Didn't do it intentionally, my mac just did it as part of the download. Trying again today downloading from my office PC. But as I noted earlier, I had this same issue with earlier updates and could never get the car to recognize the software. I've used mac and PC's, reformatted the USB stick every way possible etc and still no luck. I'm not optimistic about this one given my prior experiences.
