I just upgraded from NavNet3D MFDs to Touch 3's. I have a bunch of purchased charts that are still valid to transfer over. I have the unlock codes in a zuc file, and I have them printed too. I have put the chart files on the micro-SD card for theTouch 3 along with the zuc file, but I can't make the zuc file work to unlock them, and I really don't want to enter the codes manually.
Any advice on how to unlock these charts???
