Viable WIMP dark matter candidates are provided by models of universal extra dimensions, where the lightest Kaluza-Klein particle (LKP) is stable. The identity of the LKP depends on the unknown UV completion of the model, and in the literature, most of the focus has been put on a standard scenario where the LKP is the first Kaluza-Klein excitation of the U(1) gauge boson. For this particle, prospects for indirect detection through neutrinos from annihilations inside the Sun seems promising. However, in general it is possible to have other LKP dark matter candidates, which might change the phenomenology drastically. We will discuss the indirect neutrino detection signals for different LKP candidates.
