I have a 2003 SC430 and would like to change my current navigation system to a navigation system that would allow, bluetooth, xm radio, xm traffic, ipod interface and voice navigation. This is the system that ideally I would like to have installed:

Or the system described here:

How much do you think the whole HDD nav system + those goodies will cost you?
