Thanks guys, that sounds good, but I have one more question.
If you put the songs in folders by album, then how do you find a song if you don't remember which album it is from (i have about 6000 mp3's and can't remember which album a song is from, but I know I have it (for example))
Many thanks
Rupert
Ps. I don't like the idea of taking the dash out to run the cables so I think I will get it profesionally installed (I am not as brave as you Rodders!)
