I think it goes that if you have a digital clock in the center of your dash, ull need to take the dash off. Honesly its not that hard of a task. All ull need is a T20 and a T25 screw driver and ull b flying.
1. pull rubber off around doors
2. take off A-pillar covers (theres one or two clips behind it)
3. around the steering wheel controls, that cover needs to come off. Theres two screws underneath the casing.
4. take out all the screws, two at the speed dails, three at the top of the dash . and then two at either of the dash.
5. then pull towards your self, not up. if its the first time the dash comes off it will be tougher than usual. Might be handly to have two people. open for either side of the dash.
6. to put on do the rervese as above. (gettin the dash in to place can be tricky. its around the air bag that causes the main hassel)
And i think thats it?
If anyone else has taken off there dash they might have more hints and tips 4 ya. good luck wit ya new radio.
