Hi, I recently bought a sony cdx gt300 head unit which I received today.
I tried installing it today and there's a problem. There is power going to the head unit, I think because i can hear something inside making the noise as if i was ejecting a CD..sort of. but the head unit displays nothing and doesnt illuminate at all as if there is no power goin to it. I have tried all 3 power wire configurations with no result. Any ideas what the problem may be?
p.s. fuses are all fine.
