Are you sure about that? The first box is the one that comes with the pro speedo and it is a simple program box. The second is the optional one which, when you download the software from speed passion a) allows you to change the speedo setting from a PC and b) download firmware update from t'interweb and upload them to your speedo.
I'd check the Schumacher site as I'm pretty sure that right, by happy to stand corrected (esp as I'm about to order the latter!)
