I replaced my stock stereo on the weekend, and used both McGyver's and Lucid's instructions posted on their respective webpages (thanks guys - great help!!). Just letting everybody know that the the speaker wiring is reversed for right hand drive (RHD) models, ie you should switch the wiring instructions for the left and right speakers. It is a minor thing, but it might save somebody else 10 minutes.

Hopefully the headset speaker outputs won't be used for much longer though - should have an amp within the next week or so
