I had this with my connector and there was a time I thought I'd never be able to get it out of the car! Great anti-theft device, but not cool for taking it into the office to show off!

When I sent the unit back to Cambridge for a replacement hard drive David was wonderful enough not only to *notice* that the screw was not correct, he changed it and returned the empeg with a spare screw!
Thanks David!
