What colour is it?

I think nearly every time I've helped someone pur a car stereo in the power cables have been the wrong way round. Normally you'd have two fatter cables, one 12V permanent and one 12V that is switched with the ignition.

Can't recall exactly, either red or blue & red.

Aye, that was the initial problem. They're then correct way round now but still getting odd behaviour. Disconnecting permanent power means nothing works at all, even with the ignition on.

What happens if you swap them around? Does it stay on all the time?

Some stereos will take a feed from the light switch to change the display brightness at night. However, to be honest, it sounds like you have an actual issue with your wiring - all vehicle electrics should be at ~12-14 volts, anything less indicates a problem with voltage drop. Often a bad ground, a bad contact or even a short.

Remember, also, that current isn't restricted normally - the device will pull whatever power it needs, and if the wiring is designed for low current, then there should be a lower rated fuse to blow. As you're not blowing fuses, it sounds like a voltage problem.

It tries to stay on but doesn't seem to have enough juice yo boot up (perhaps because it needs both pins to have power? I dunno)

Your permanent should definitely power it just fine. As Dan said, sounds like a few issues with wiring. Or some odd extra wires that the car provides that aren't needed.

Have you checked the two main power lines are 12V?

Think I've fixed it. There was a permanent 12v coming in from the antenna motor pin. That's supposed to be an output pin from the radio to the antenna motor so was probably playing merry hell with the circuit. Snipped the wire and seems to be working correctly now.

Yeah, I can't imagine that was doing you any favours.

Your welcome.

What about my welcome ect

Maybe you forgot to plug it in.

I think I need to up the agp voltage.

2GB TBH.

Heh, that's actually the size of SD card I was going to put in it :-D

Trig would be proud :D
