Connecting devices to main unit. – GVSmartApp Review

As I have read other reviews, I have the same exact problem. I cannot connect ANY of my devices to the machine. Followed every step, watched youtube video, read the guide, emailed WOW, and still ne success. I feel jipped. Very disappointed. Update: After several back and forth emails with customer service, I was able to update the machine’s software, which enabled me to successfully purchase, and download new song packs! Now I give it 5 stars!
