Seidio InnoDock Questions

[Torx]

i need a dock for my desk and maybe my car.

my questions are.. to those that own one..
do both the regular and junior version have 3.5mm jack in the back?
on the website, only the standard dock (silver one) mentions the 3.5 jack, but not the junior (black one).

can anyone confirm if these round docks fit into a cup holder of a car?
i could soooo use this as an mp3 player/nav with sound output to my car stereo (i have an aux adapter installed) And not have to deal with any major modifications..
