If you want an ipod hookup, you can get an iTrip or any other plug-in radio transmitter for 10-50$ at Wal-mart.
Higher-end ones not only play your music, they also charge your device.
This is advice is as good as a nissan sentra is a good car...
I dont think you can get an M with the Nav in 07 and NOT have Sat radio. There is no SAT button anyway. Hit the voice button command button on the steering wheel and say, "Tune channel one" and see what happens. Im going to bet you have it.
As for IPod, if you look at the back your center console, from the back seat, open the compartments there and see if there are A/V inputs. If so, you can buy a simple cable to go from your headphone-out on your IPod to the input there. Once connected, you press the Source button on the steering wheel until you get to AUX on the display. The sound from those inputs plays through the cars stereo.
