The only other option is one of those crappy FM tuners, No way, or Aftermarket stereo. I have nav and I wanted to keep steeringwheel controls and have track info, not to mention charging the iPod while playing it. The install wasnt too bad but finding the right place(tucked above the stereo under top of dash) for the box/computer thingy was difficult. Wiring was simple. Plug and play. I ran the cord to my center console and cut a hole in the box. The thing displays info, uses steering wheel controls, works with factory Nav RB1, and charges iPod. All were very necessary to me. However it works pretty poorly sometimes. It seems to just get "messed up" and will show wrong track, artist, genre, no info at all. There seems to be no solution except waiting it out and restarting the radio or unplugging the ipod. When it works it works well and does all I ask, when it doesnt Its frustrating as hell and distracts from driving as you try and sort it out. It does play the iPhone which isnt even advertised but doesnt charge it. Shouldve waited til they fixed the errors in the system. $200 to plug in an iPod???!!!!! Thats enough to buy and iPod in the first place~!!!!! But the other options just arent options. Glad I got it but NOT blown away.
