XM Radio

I would like to add the XM or Sirius radio feature to my stock JBL Navigation system that came with my 4Runner. Does anyone have any recommendation on where to place the unit and screen without making the car look "cheap" or worse? Also, does anyone know of a good unit that would accomplish this or where I could find pictures of what the final results would look like?

try www.cardomain.com its supposed to be a car show-off site, but its mostly just a stereo show-off site.
