Jan, you may be looking for trouble. It hasn't been 6 months since the IA was here refusing to sign the annual because of a radio with no 337! It was a TSO'd radio but no 337 was filed and what's a guy going to say? I would not do anything that has to be hooked into the 12v power without very seriously considering finding an IA to file the form. It doesn't seem like a "major alteration" but it is getting to the point where adding anything is considered by a lot of these people to require a 337. He ranted and raved about it and generally lowered my opinion of the whole maintenance process.
