Thanks 12Ounce, a blocking diode might indeed be a smart idea; I hadn't thought of it yet.

I'm pretty comfortable with the radio electrical cuz if anything goes wrong i can just change the fuse.

No, don't connect it to the radio's ground wire, because that's always at ground potential regardless of whether the ignition is switched on or off, so it won't achieve anything and it certainly won't make the unit switch automatically. I imagine that yellow wire might be intended to hook into the alarm system, so the unit would switch on automatically when the alarm system is armed.
I got my computer all finished so I can take a look at the wiring diagrams later. Oh yes, one other option would be simply to wire it via a switch, maybe a hidden one, and just switch it on manually when you park the car. I'll see if I can find an easy automatic switching solution in the area of the radio though.
