So far so good! Had an Integra DHC 9.9, it was nice but difficult for me to get along with. 1st question, how do I register this? Look at website and I don't see a place to do it. 2nd question, the FM antennae comes in 02ea pieces, the cable and a coaxial connector. How do they fit together? I have a background in electronics from the Navy and can't attach a FM antennae. Sheesh! 3rd and last question, best way to connect amazon 4k fire stick to this. Love the bluetooth with this.
