Hey Willie, I'd have to dig up the paperwork because I actually bought it when I bought the bike. It was through the dealer. I can't for the life of me remember what I paid. It wasn't a fortune but it wasn't cheap either. Lol. I installed it myself when I got home. It was super simple, it's just a box that you hide on the bike. I installed it under the seat. It has a rechargeable battery built in that last for months. The app tells you when it's getting low and I just throw it on battery charging block thing overnight and it's good to go. It's just a micro - usb like charging your Sena, except the battery lasts way longer. You could plug it in too, I just find it's easier to use those blocks. There's no monthly fees or anything like that. Just purchase it one time and set it up with the app and it's good to go. Works great! Like I said the piece of mind while I'm away from the bike is great. I go to rallies and MotoAmerica races and stuff like that and it's like having someone watching over your bike while you're away from it! LOL
