There has been discussion of this ipod desire on some other forums, but I believe there is a good possibility that an integrated ipod solution like the LE has is, uh, possible.
The 2009 Murano Service Manual (which can be downloaded for a fee from nissanhelp.com) shows an "IPOD Adapter" installed in the center console just forward of the gear selector, presumably on the LE, although the Service Manual does not specify that. It shows it in sections of the service manual for Murano with Nav, and in the sections Without NAV.
Further, the Nissan GTR, which has the same Bose Audio/Music Box/Nav system as that available on the Murano SL and included in the LE, has a "Dealer Installed" factory option for iPod integration. That option is just a small box with some cables, according to a photo on one Nissan dealer's parts site. That is a $400 option (installed) on the GTR.
I would not be at all surprised if there is not already a wiring connector on SLs with the Bose/Music Box/Nav packages at the location shown in the Service Manual, and install of the GTR option might be easy. Maybe...
I have not yet had the courage to remove my new SL's console to look in the location describe in the Service Manual for the IPOD Adapter. And now our new SL (AWD) is on loan to our daughters for a skiing trip, so it will be a few more days before I have to re-examine my fear of taking tools to the perfect console of our perfect new CUV...
Anyone else want to look???
