hey syx
mate after i bought the TT i went custom with the mounting....i bought a 2nd ashtray and cut a hole in the back of it and piped the TT through the hole and attached it with velcro as you can see, (dont know if you tried to detach it though)
you can detach it, take the ashtray out, push the TT back into the recess behind the ashtray and then replace the ashtray and it'll look sweet, they shouldnt look twice (maybe just a strip of black tape to cover the rectangular hole)
BUT... if you do this, disconnect the battery first!!!! the wiring of the TT is such that if you pull it too hard in one direction it will short out the car and bust the main fusable link (2nd green fuse in the fuse box in the boot) after you have finsished hinding the turbo timer hookup the battery and you should be sweet (same in reverse - unhook the battery so you dont blow that fuse.)
if that fuse blows there will be no power to the car at all even the immobiliser will die
the good news is IF all else fails and you do fry that fuse
1 they about 20 bucks at your local nissan dealer and
2 there is a second fuse next to it that is the exact same type that controls the hicas system and you can pull that one and replace the main link with it so you can drive to nissan for a new one for the hicas
phew that was a long post, hope it made sense
