Yeah, it has the velcro. So by "came with the car", you're saying it's not installed? It did come with the V1. It cam in the original box, along with the suction cups and whatnot. It's easy, just run wire from the back of the fuse panel, perhaps from the ciggy lighter circuit. You can install this in any car, it's not vehicle specific. You supply 12 volts to the adaptor thing, and you supply your own cord from the adaptor to the V1.

If you are really struggling, then any stereo installer can install it for you.
