This style wiper blade was originally fitted on Volvo XC60 models up until mid 2011. Volvo later superseded all these earlier XC60 models to this style wiper blade and arm. The wiper arm and blade combination are interchangable as long as you replace them together and match the blade to the arm.
The easiest way to tell them apart is by looking at the arm. This is the earlier style blade for the straight style arm. The later cars used a "bent" arm.
If your XC60 still uses the straight style arm this blade is a direct fit. If you want to update to the later style you'll need to update both the arm and blade.
