I finally completed the integration of an iPOD connection to my Becker Radio Cassette in my AMG 6.9 project; Ended up using a W123 air cond compressor "On / Off" switch to switch between iPOD and the Radio Casette; added an Alpine AMP and all new speakers incl dash mounted tweeters. The cord out of teh centre console is a bit tacky but this will be hidden by the Burl wood centre console box that is on its way from Benzwood.com.
