Abstract: We classify $C_0(X)$-endomorphisms of stable continuous-trace $C^\ast$-algebras up to inner automorphism by a surjective multiplicative invariant taking values in finite-dimensional vector bundles over the spectrum. Specializing to automorphisms, this gives a different approach to results of Lance, Smith, Phillips and Raeburn.
