It might be possible but check the following things first:
On the rear of the player is an information panel that will state the power supply requirements. If it does not include 230V AC as an acceptable power supply, then it's not going to work.
Next, check the mains lead. Does it look like a figure 8? If so, it is not a double insulated lead and therefore is not approved for use in the UK. UK mains wiring demands a second insulator because of the higher voltage used for mains power and therefore the higher risk of making contact with it.
If you can confirm that both of these points are in order, there should be no reason why the player won't work in the UK.
In the UK the neutral wire is 'blue'.
Yes, a US compact disc will play on a UK CD player. There is no region coding on music CDs.
That is potentially dangerous and should never be done. See an electrician about this problem.
CD - or DVD ! If it's CD - then yes, if it's a DVD, then nope - the playback machines are different.
No, the Ireland plug is different from the UK plug. Ireland uses a Type G plug, while the UK uses a Type G plug.
This is not true in all plugs it all depends on the manufacturer and the product. Plug wires come in all different colors such as red, black, brown, yellow, blue, and so on. So as I said the wire being brown is indicative of a certain manufacturer or product.
In the UK Brown is the live, blue is the neutral and green/yellow is the earth. The live and neutral are the two wires that normally carry the current.
Most new vehicles are fitted with them as standard on the more expensive models.
A four wire plug suggests to me that it is for split voltages. 120/240, hot - neutral - hot - ground will be the four blade connections for shore power in the US. With UK shore power three wire there will be no neutral as you know it. 120 volt equipment will not work. If there is a special berth for 120/240 shore power that is what you will need to tie up to.
For the UK, you will need a Type G plug adapter.

Yes, Ireland uses the same type of plug as the UK, which is the Type G plug.
