iSimple Gateway for many Nissan/Infiniti models (G35/350Z, Altima/Maxima, Armada, etc.). Creates two AUX ports to plugin your phone using your SAT RADIO button: http://www.pac-audio.com/productDeta...&CategoryID=45

But we all know the volume of that system is not satisfying (it is much quieter than CDs or the radio) - so I boosted the sound with an in-line amp:
I also wanted a way to charge that amp and adding Bluetooth seemed like a good idea, so I got one of these:
This system worked really well - with the volume on the amp turned all the way up, you could get really good sound out of the factory system (without cranking it to 30 on the OEM head unit) and it was all wireless. You just have to turn the amp on/off each time you use it (you can leave it on for short periods of time, it does have a pretty good internal battery).

The complete package is yours for $50 - shipped.
