Do you listen to the radio at all? If you do, then keep the headunit.
If you keep the headunit, you also have your XM already working.
Now, if you keep the headunit and XM, you may have an issue in that the headunit doesn't have the ability to have two AUX devices plugged in. That's pretty common.

Some things I would like to do are:
two video sources (back seat movie, touchscreen nav)
XM radio
vehicle diagnostics
FM radio (even though I don't use it much)
Two video screens. Two video sources would be like a DVD player and a video game console. The screens aren't sources.

I plan to use streetdeck with mappoint 2007.
Try MapPoint2006. MapPoint2007 doesn't work, AFAIK.
When you purchase StreetDeck, you get the proper map data, anyway.
