I'm thinking of the same install location for my XM Commander in my 02 Terra. How do you plan on mounting the display panel? I am thinking of popping off the outside 'hole' on the dash bezel under the ac controls and using a Pro Fit XM Commander Bug mount and routing the cables though the hole to the head unit and control unit. If there is enough space with the bug I may try to mount the bug under the bezel only leaving the arms exposed so I can detach the control panel and hide it away from those that want my XM.
