When I had a VW GTI, there was an original Volkswagen part- a plastic cover plate that's normally used to cover the hole in models that didn't have a radio. I used this for a long time with a pull-out CD player, and also used it for the Empeg. It worked very well and I never had any thefts when I used it.
Unfortunately, there doesn't seem to be a corresponding part for my Honda. When I asked about it at the dealership, the parts-guy told me that Hondas don't come without a radio, so there's no such thing as this kind of a part. So I just have a gaping hole now when I leave my car. I can't use the VW part because it doesn't fit and wouldn't look right anyway.
There was a thread in the "Wish List" forum recently (shortly before you joined this BBS) regarding this topic. Some folks wanted to turn the empty bay into a storage compartment. A plastic sleeve insert with a door on the front was the idea (sort of like the
storage compartment in my Honda). It was even suggested that they use a part from the docking connector to secure it, and also wire the line-ins to the line-outs so that it would work as a pass-through connection when you didn't have the Empeg with you. No one has ever done this as a custom job, though, and I think the Empeg guys decided that it'd be too expensive to develop one themselves.
