Don't know if I'm the only one that has seen this but if I set the "Random" checkbox for my 430N when listening to the iPod I have noticed that it goes away when the Jeep is turned off and back on again. That's not too bad but here's the rub. Typically when I go into the MENU feature while the iPod is selected the Random and Repeat button are gone. At first I thought that maybe they were disabled when the vehicle was moving but that proved not to be the case. So I began experimenting and here is how you fix it (for those of you that have the problem) first select the media button, cycle through the 3 soft buttons on the top left making sure to press AUX last. Then go back to the iPod screen, press MENU and magically the Random and Repeat buttons are back. I will be taking this problem to the dealership eventually as I suspect it is some kind of software problem that can be reflashed.
