We show new examples of generalized Gelfand pairs of the form $(K,N)$ by considering a family of 3-step nilpotent Lie groups $N:=S\ltimes H$, where $H$ is the $(2n+1)$ dimensional Heisenberg group, $S$ is the subgroup of $(n\times n)$ symmetric matrices and $K$ is a non compact, unimodular subgroup of automorphism of $N$. Also, we determine the automorphism group of $N$.
