Will this be compatible with an older insignia tv? Nope, it's not smart.

Mary, thank you for your question. Our remotes do have multiple direct codes for Insignia, but If none of the codes provided offer the desired functionality, we recommend that you try the Auto Code Search Method. This method will search through the codes stored in this remote to possibly find a code from an alternate brand that will offer full or partial functionality with your device. You can view all brands and codes on byjasco.com/remotecodes.
