Crutchfield Customer Review (What's this?)

Easy to set up. Additional connections are needed and they have to log into the system to activate the license. This was a small pain. They did not let me know when the process was complete.

Pros: Easy to set it up. Great value

Cons: Fusion needed to sign into the server to activate the license. This was a small inconvenience.
