A novel sodium zirconium carbonate is further described which contains from about 2 wt % to about 5 wt % Na; from about 44 wt % to about 50 wt % ZrO2; from about 12 wt % to about 18 wt % CO32; and from about 32 wt % to about 35 wt % H2O. Additionally, the client device is implemented to present the interactive media guide to the user. The downloaded upgrade may then be installed by an installation means. The ejection channel is constructed in one piece with the instrument panel.
