Anybody found the best place to mount a satellite radio

[guyzilla]

in an '03 H2? I was considering the dash right behind the AC vents but it would be awfully visible to thieves? or right under the ignition but it's kinda hard to see and difficult to release the hatch to make it portable?
Also does the 3M sticky tape used to mount one work well (or too well, will i ever be able to remove the stickum?)
I will not be hardwiring it since i'm afraid of removing the stereo so i will be playing it thru an fm frequency.
Thanks.
