Firstly is a Trimble GPS antena http://www.trimble.com/mgis_patch_antenna.shtml which i can only guess at being something to do with a tracker?
the second is an Ericsson GSM Module wich looks like it might be something to do with trying to get internet access through a mobile phone while on the go but to be honest if you hadnt guessed already I've no idea what it is
They might both be for the same purpose but not sure so some night I'll rip both out as theres a ton of wires run all through the front panel and into the cabin.
Just for nosiness anybody know what they are for?
