Have you tried to hook the red wire ( 12v ignition wire), and the Yellow (12v battery wire) directly up to a constant power wire to check that the head unit isn't faulty. You may still have to turn the key on to ACC for power.

i have a similar problem. i got my new head unit wired in and working used it that day for a few hours then parked it over night and the next day the fuse in the radio was blown. I replaced the fuse and re-did some of the wiring to the radio just to be safe really. it worked that day as well but the next day the radio wouldn't turn on. all the fuses are fine and it has both the constant and the ignition controlled power going to it cant figure out what could be wrong. could the head unit be fried?
