We have detected and mapped the linear polarization of the CO 3-2, SiS 19-18 and CS 7-6 lines. The polarization arises at a distance of ~450 AU from the star and is blueshifted with respect the Stokes I. The SiS 19-18 polarization pattern appears to be consistent with a locally radial magnetic field configuration. However, the CO 3-2 and CS 7-6 line polarization suggests an overall complex magnetic field morphology within the envelope.
