Automorphism groups of virtually cyclic groups

Question

Let $V$ be a virtually cyclic group. Then is $Aut(V)$ also a virtually cyclic group?

This is true when $V$ is a finite group (zero-ended) and when $V = C_\infty, D_\infty$ (both two-ended).

Answer 1

In Finitely generated groups with virtually free automorphism groups, by M.R. Pettet, it is proved in theorem 3.4 that the automorphism group $Aut(G)$ of a finitely generated group is virtually cyclic if and only if both $Z(G)$ and $G/Z(G)$ are virtually cyclic.
