Can't get aftermarket head unit to power up?

Hey guys- just bought a new jvc kw-r910bt. I installed everything the way the directions stated and connected all the wires to their corresponding spots. I can't get the head unit to power on at all not can I do anything with it. Is there anu other things I should take a look at before calling crutch field tomorrow? I've got a 2006 double can trd sport with a non jbl system. Thanks for any help!

 

Sorry I did not see this before. Did you get it resolved?

 

Yeah I actually ended up figuring it out. A fuse must have blown when I hooked the new stereo in because I didn't have it grounded well enough. It works like a charm now!
