Azimuthal asymmetries in unpolarized SIDIS can be used to probe the transverse momentum of the quarks inside the nucleon. Furthermore, they give access to the so-far unmeasured Boer-Mulders function. In this contribution, results on these asymmetries, extracted separately for positive and negative hadrons, from the COMPASS data taken with a 160 GeV/c {mu}{sup +} beam on a deuteron target will be reported and compared to theoretical predictions.
