hi,

iv'e got the original concert head unit in my 99 audi a3, i know that at least four pioneer cd changers fit ie dp601 dp610 dp801 dp810.

my problem is that while looking for these on ebay i found a dp600, so i bought it and even though it powers up and ejects etc the head unit won't accept it.

my question is, is there anything i can do with this dp600 to get it to work or will i have to find one of the other models? and if i find one is it just a case of plug it in and it will work?

thanks
xrwardy.
