Apparently the Soundgate M2 Car Dock is discontinued - see this page when you try to get the pdf manual from the site. Just an FYI for anyone that was thinking about buying the Soundgate M2 Car Dock or those that have it and want a spare (like me). Amazon has them for $9.95 and it qualifies for Supersaver Shipping.
