I'm trying to get to the bottom of a problem..
I want to replace the oem headunit for something that can handle mp3's and
have some expandability..

Problem is, I can't get a definite answer on fitment!

Car has balanced outputs from head unit, to an external amp, this then feeds
7 speakers.
Some info he http://www.mitt-eget.com/saab/faq_audio.shtml#head

Can anyone help?
