recomendations wanted, nav, xm, camera

Hi; I am looking for a Kenwood or Pioneer Double Din stero to put in my wife's car. It has to have Navigation, and she listens to XM Radio all the time, so it has to have that. I also want a back up camera that will come on when I put it in reverse. Any recommendations on which unit to get? What all will I need for the camera and xm control? Thanks for any assistance

I suggest Kenwood units 5160 or 6160. They use Garmin navigation, are upgradable to XM or HD radio. Any back up camera will work. XM tuner you need is 700XMKENV1DTS Performance

Thanks for taking the time to reply. I will look into the Kenwoods.
