Sounds like a blown fuse to me, or a bad connection breaking down under load.

I suspect when you quickly lashed it in that you may not have had permanent and ignition lives the right way round, and now you are doing it properly, this fault has now been highlighted. Check carefully using a meter

I'm sure some bugger will politely correct me if I have this wrong but didn't the Orange and Yellow (switched / Unswitched) colours swap around at sometime  :-\

If it was a blown fuse there would be no power at all....the power is there when not plugged into either headunit....oh well time to.break.out multimeter

What about taking the red and yellow wires from the HU side (hopefully) they are on bullet connectors? If join them together with a spare bit of wire, wrap in tape for safety and then pick up another 12v in the car, this will check all the other wiring (earth mainly) and stereo. If you can use a fuse bit of wire.

I have had many instances where blown fuses have not blown the way that they should, and the blown  "tails" touch each other inside the housing thus creating a circuit, allowing nothing more than leakage current to pass. If anything proper is connected, the surge in current cannot pass through the blown bits, makes diagnosing a blown fuse a little more difficult.

But . . . . Starting to see this on a more frequent basis now as cars are brought in that have defeated the owners in a similar scenario  ;)

Out of curiosity, what make and model of stereo did you have fitted in there as standard?

If 2 digit one, like CD30 or CD70, then the power connections are CAN-BUS and data ones, and not suitable for aftermarket stereo, where you need to take the supply from the back of the Hazzard switch.

If 4 digit one, CDR2005 etc, the the orange and red need to need swapped over on your Alpine loom.

Didn't know you had 1 Alpine D310, let alone 2...

I also have the same unit and its oppsing brilliant piece of kit. Not installed it into the Omega but it has been in my Vectra for many months - faultless - until I scrapped the car. I am in the process of repairing it, as the little cog that pushes the screen out when its switched on is knackered, I happened to buy a D300 at Billing. They are basically the same H/U so it should be PnP or I'll just swap the cogs over from 1 to t'other...

I'm also wanting to get hold of the navigation unit for it too, but everytime 1 comes up on Ebay, I always get out bid LOL
