Query: DOA - The one I received shows no sign of life

After wiring it up to the car, the unit will not turn on. Yes I checked the power after the fuse. The support says to take it back to the installer. I like the idea of this product but after putting in the effort to install it and having a dead product and no one to call, I may go with a new in-dash HD radio.
