I recieved my Empeg unit last week, and have been using it at home. I've installed 4G of music already, and have enjoyed playing it on my home amp.

I just had it installed today in my 2000 4-Runner, and it won't power up. The blue light blinks, but it won't power up when I hit the buttons. I plugged the unit back in AC, and it powered up fine

I had the unit professionally installed, and they were stumped. They triple checked power, ground, and ignition connections. They did find that the 3A fuse was blown, and replaced it. Any ideas?
