I'm new to the forum, and Muranos in general, but as someone who's put in an aftermarket iPod interface for a 2000 Accord and a 2006 Accord, it usually takes awhile for a manufacturer to catch up with a new model stereo. If the 09 Murano's entertainment system guts are a lot different than previous models, chances are it will be awhile before anyone comes up with an after-market interface - at least one as nice as the one that comes with the LE. A lot of the interfaces for the Hondas required you to give up something (either NAV, XM, or something).
Anyone know who manufactures the one that comes with the LE? I wonder if they sell it by itself for Murano S and SL owners to put in after the fact.
I just found a site called "yournissanparts.com" that has iPod interfaces that I've read good things about - it sounds like they work almost exactly like the one in the LE with a few minor exceptions - and you can get one that is compatible with the factory XM. The problem is it only lists compatibility up to the 06 Murano - not sure if it would work with the 07 or 09 since I don't know what changes have been made since 06.
Here's the link to the one for radios with Sat:

I'll keep my eyes peeled for you, but initially I think you're going to be stuck using your iPod through the aux jack and controlling it from the iPod screen. Hope someone else has better news for you.
