Firstly start with the trim around gearstick, quite easy to pull up. This should show two torx screws by ashtray. next you need to remove trim at top the piece that runs the length of the dash, use a plastic trim remove or a piece of strong plastic to help remove trim start at the steering wheel end and lift gently, once removed i taped to dash with masking tape to hold it out of position this way i didnt need to remove any connectors. This should show the top two torx screws. remove all of these, and place the removed part over the gear stick out of the way. Next there are 4 torx screws to remove from the old unit and 2 clips either side to unclip. Once you have done this the unit is out. There is one more clip to remove the units harness from the back of it and removed the aerial. The new unit has a canbus connector and such like that need to be put in the new unit first just plug in connectors, then i just connected the harness to the new unit using old clips and refit the aerial. And refitted using the reverse insturctions. Hope this helps.
