I'm getting it installed in place of the original headunit, which is a 2-din CD and tape unit. You can see it in the bottom left of this picture



I have a dash kit to convert it to 1-din plus a pocket, and I have a wiring harness that (should) connect the empeg to the existing amp, allowing me to keep the standard amp and speakers. Hopefully.

Cambridge Car Audio have quoted me £35 and said it should take about an hour.
