Set pandora connection to "iPhone" even if you don't have an iphone.  That's what I do on my 4600 and Pandora no longer appears in the source list.

If you have an iPhone, I don't know what you'd do.

S4 is not compatible with MirrorLink, and even if you can find a phone that is "supposed" to be compatible, the Android version it's been updated to might not.

MirrorLink is a buggy mess and it doesn't work.
