I want to build a dock for my car

“So, the big question is: is there some way to use the LOD to turn off the Fuze?  I.e., a signal to some other pin, or something?”

Doing some more web searching, it doesn’t look like there’s any known pin in the sync cable connector that would directly do this.   That still leaves the possibility of indirect function (i.e., removal of 5v if no USB data pin was used).  Or, an as-yet-undefined pin.
