Having trouble updating from build 20136 to 20196. I have downloaded the latest version of the updater and about half way through writing files to my USB the program quits. In the past I successfully created all I needed to go from sync 3 to 3.4.20136 using manual method but at the time I was also updating maps. I do not want to update maps nor do I need to update the Gracenotes just APP and VOICE. Could someone tell me how to create the auto install list to do this manually as I cannot get the program to function?
