hi matt,
i know everyone already posted same as im about to but ill add my pics too. i personally think the roof console is the best place. i found under the dash theres not enought space and you would hit ur legs on it and have the mic wire get in the way.
some people have custom made dash jobs which look really neat but i think quite a lot of effort.
i know some people dont like the roof option as they say the mic coil gets in the way of sight but you can always fold it away or tuck it under sun visors etc.
mine isnt installed yet but ive done the wiring as you can see from pic. there was the factory power supply behind the panel but i left it as is and brought new power up as i wasnt sure about fuses etc. i got some power from under the dash and fused it there and brought the wired up to the overhead with the antenna cable.
anyway hope this helps a little
good luck
larry
