I had reformatted the card prior to putting the files on it. I can't get the card out of the head unit since it won't respond to any buttons. Will have to take the bezel off and see if I can manage to squeeze it out that way.
Just tried the supereasymethod on my Z130 but it gets to about 22% and tells me that I have the wrong SD card and to insert the correct one. Used 7-zip to unzip the files....would it be better to use WinZip instead?
