Similar nav/sound system for non-Prius?

Hi all, my wife and I just took delivery on a new 2011 Prius 3 with the nav system (with Bluetooth, XM satellite radio, etc). It's our first Prius, and we've been enjoying it a lot.

We were thinking that we'd like to get a similar nav/sound system for our other car, a 2003 Jeep Grand Cherokee. It would be nice to stay with the same OEM manufacturer so that the command patterns would be as similar as possible. The main functions we're looking for are street GPS, satellite radio, Bluetooth and somewhere to plug in a classic iPod. We were thinking it would probably make sense to get a family subscription for the satellite radio covering more than one vehicle (this I gather is possible?).

Given all of the above, are there makes/models of systems you'd recommend? Thanks for any ideas.
