Does anyone know of a place where I can find a detailed write-up on the '03/'04 4Runner navigation system? If there isn't a place, will somebody please provide this information?

In addition to the basic information, I'm specifically interested in any changes to the '04 system besides the publicized back-up camera. Does anyone know if the '04 version is currently or can be (with a firmware update) XM or Sirius capable (Like the new system in the Solara)? Does the '04 version support the 5 million points of interest (like the new system in the Solara) or the current 2 million? Are the points of interest part of the DVD updates (if they are, would the '03 system support 5 million data points with an update?) Anyway... Any information would be appreciated... For a good example of what I'm looking for, check this site out for Jeep's RB1 system...
