Using data collected by FOCUS, we present a preliminary measurement for the vector meson semileptonic branching ratio $\frac{\Gamma(D^+ \to \rho^0 \mu^+ \nu)}{\Gamma(D^+ \to \overline{K}^{*0} \mu^+ \nu)}$. Using a sample of 397 ± 42 and 11, 811 ± 151 D+ → ρ0μ+ν and $D^+ \to \overline{K}^{*0} \mu^+ \nu$ events, respectively, we find $\frac{\Gamma(D^+ \to \rho^0 \mu^+ \nu)}{\Gamma(D^+ \to \overline{K}^{*0} \mu^+ \nu)} = 0.0381 \pm 0.0041 \pm 0.0052$.
