Is there any reason to upgrade my stock hu to a scion one? Is the sound quality change as drastic as in previous T4R? If so, what is the exact model number of the 6 disc changer in the earlier scion models? (I do not want to pay 300 for the new 08 6 disc) Will the earlier scion 6 disc work with my 07 T4R? Thanks
