Thanks for info you guys. I should have read the FAQ but to be honest I had the Empeg in a Golf for a year and thought I had remembered most of the installation stuff.

The 325i is a saloon and it is the latest model with the integrated head unit in the dash, so it looks like I am pretty well beat on the dash install. Our second car is a 15 Yr old Merc 190 so it looks like it is going to be home for the Empeg for the forseeable future :-( I have a BMW Z4 on order and it looks like another nightmare to install in. Maybe by next year some of the more enterprising members here will have installed into a Z4.

Thanks for your help folks.
