I bought it online years ago and shelved it. It was about $100. They are all over the internet. Audivox makes them.
It works very well for the past year and a half.
Not the easiest install, you need to have some mechanical and electrical knowledge.
Honestly I use the throttle meister more often.
The CC is for open road point A to B when I just want to set it and not worry about the speed varying drastically. It will keep you out of trouble.
