JDI Posted December 26, 2008 Share Posted December 26, 2008 Tried copying Pioneer Navigation DVD-Rom for backup. Everything appaers to be correct including Book type of DVD-Rom but navigation unit says format error and will not read. What am I doing wrong or maybe I cannot do this.

blutach Posted December 27, 2008 Share Posted December 27, 2008 No need to think corny - you are spot on. @JDI - treat your disc very very carefully or buy a Tom Tom which uses an SD Card. Regards Link to comment Share on other sites More sharing options...
