Great write up . I thought about doing a write up about my install with the Bose system but I my pictures are not as clear as yours. For anybody contemplating doing this but has Bose you need to either replace the amp or use NavTv's optical interface available here:-http://www.nav.tv/products/head-unit-replacement-por-hur It's a very simple unit requiring only about 6 connections... pity it costs the earth.
