need an RB1 head unit for 2004

[sssikvipe]

Happy summer everyone. My OEM unit is fried and I have just read in the forums that i can use the RB1 unit without any mods. Is there a certain model I will need for my 04. Someone posted a pretty discriptive install method (thx) so I should be able to handle that. Do I need any special wiring, fuse changes etc. Thanks for the replies
