Onstar Box Location on a 2007 Lucerne

[210010243]

I am interested in the conversion box; but would like to know the location of the current onstar box on a 2007 Buick Lucerne.

I would like to scope out what the job entails and if I can get to it>

I cannot say with 100% certainty, but it most likely is like my 2006 Lucerne. It is located behind the hard plastic at the very back of the trunk on the passenger side.
