The european Nokia hands free car kits come with 5 wires: red (permanent power), blue (switched power), green (power to antenna), black (ground) & yellow (radio mute). Are these color codes the same as in the states?

I know that the US OEM MB cell phones are different, but, David, if you can get yourself a car kit for your Samsung, you should be able to connect it to some of the existing wiring and parts...
