Bought my new-to-me E430. Runs flawlessly.

On the front license plate holder, there's what appears to be a remote radar detector device. In the instrument cluster, there are two red lights and one yellow light - I thought they were Mercedes, but after reading the owner's manual, there is no mention of these indicators. If not stock, whoever installed them was a pro - they look factory and blend right in.

Above the driver's feet, there is a toggle switch and a small button on the right side of the well, mounted to the under-dash trim.

On the parking brake side, there is a small light, and a two-in-one rotary switch. The outer, shorter portion is a three position rotary switch, and the inner is probably the volume control.

I've turned the toggle to both positions, and nothing happens.

Does any of this seem familiar to any of you? What brand would this be?

If nobody know, I guess I'll take the lower panel off and try to figure it all out, but it sure would be easier if I had a book.
