We present here a complete description of the phase diagram of (TMTSF)2ReO4 when pressure is applied at room temperature using resistivity measurements along both a and c-axes. In a large range of pressure and temperature, the semiconducting order characterized by the wave-vector $\rm q1=(1/2,1/2,1/2)$ coexists with the various phases (spin density wave and superconductivity) exhibited by the metallic ordered phase ( $\rm q2=(0,1/2,1/2)$) down to the lowest temperatures.
