We describe the infrared spectrum of the galactic supersoft X-ray source MR Vel (RX J0925.7-4758) in the wavelength range of 1.1-2.6µm. We find Paschen, Brackett, HeI, HeII and neutral and ionized oxygen lines in emission. No traces of the secondary star were found. P-Cygni profiles were observed in Paschen β and Brackett γ, from which we conclude that these lines arise in a wind. Fitting the optical and infrared energy distribution with a supercritical disk model, incorporating white dwarf and secondary star contributions, we were able to constrain the distance to 2-5kpc, which implies an absolute magnitude M_V between -2 and 0.
