I have an Insignia TV with Fire built in. I don't see an option for this in the Insignia TV options but thought if I just add a FireTV as a setup box I could do that. But I don't see Amazon or Fire showing up in the controls. I think that is because they are bluetooth? But presumably if the TV works with an IR remote then I should be able to control the basic functions - Home, navigation, etc? Any ideas how I could get this working? Thanks.
