Thanks for all the replies gentlemen. Sounds like I'm stuck with it unless I want to subdivide the music into 5 folders of 6k songs or less. I wish it would just only do that when I have the audio source set to USB. Sounds like a software engineer took a coding shortcut, as there is no reason why it should announce when I'm on XM or FM and am trying to make a phone call with one push of the voice button.
BTW, I should have been more specific, its 30k files, not necessarily 30k songs. Some are smaller in size such as comedy skits, etc. Also, many are oldies songs which inherently consume less space since songs where much shorter back then and are also at lower bit rates. It all averages out though.
