yep a torx screw driver ( a T20h is what i use) , a flat head (with masking tape on the blad to avoid scratches and imagination is all that really needed to take the interior appart, i done it one day in a car park while i was waiitng to my brother to sit his bus drivers test out of sheer boredome. getting back to gether is the trick but with once you know how renault connect things it pretty simple.( not too many screws mainly clips)
one way i found when i was installing the aux ports in mine and my brother clios there is a lor of room going in fornt of the air bag, like right behind the silver trim in the dash, uou should be able to thread a cable through there.
but if its ti consol, the rasies way i found was to first remove the ash tray, then pul the plastic panel withthe cup holders and lighter, up at the lighter edge then pull it towards the gear stick, i think you should be able to do the job without taking any thing else out but i'm lazy, but the clio is pretty easy to work out.
