Thanks to ALL your help, a chat with David at Empeg, a couple of hours in someone else's office getting to grips with a PC and a lot of downloading of software later, I now have empeg car friendly with Emplode (updated version) via a USB cable on my Mac using Virtual PC. Phew!

Once again - thanks so much to all of you. I could not have done this without you.

Sally : )

PS: I'll post some pics of my Roadster install once everything's together.
