Worst part about furrion was poor channel reception. Just put in lg 32'' . I can play DVDs ok through it, but cant put tv audio back through irv66. Tv reception and number of OTA channels scanned is outstanding. Guess you cant have everything!
I ditched the little factory Furrion and replaced it with a 28" TCL Roku. Pleasantly surprised to find that it included an optical audio out, used that for a mini soundbar. It also has a headphone jack which can be easily adapted to dual RCA outputs.
I found it to be a worthwhile and cheap upgrade, and I can't believe how light these TVs are now!
