Try these instructions. Should be the same on 2005 as these were for 2001-2004.
Remember to pull straight out towards you. grip the panel from in the ash tray holder. Remember, its plastic, so use some care, and the tabs are not the thickest I have seen, so take care. To remove the lower fascia panel; here is how:
1. remove the ashtray
2. remove the 2 screws as the ashtray holder
3. push the lower panel (under ashtray) down with moderate force and then pull the lower panel out with moderate force also.
remove upper fascia panel:
1. remove lower panel first as list above
2. remove 2 screws under the stereo panel when lower panel is out then you will see that 2 screws
3. pull the upper panel straight out with some force as well.
Pretty easy to remove and the radio screws are right in front after the facia is off.
