I honestly don't know, I didn't have my ruler in my back pocket, just my phone in my front pocket and just happened to remember that the subject had come up and it was an opportunity to get a pic of them off the truck.
A rough (and hopefully close enough for rivet counters) guess is about 8 inches square and 3 inches high not including the hump sticking up in the middle. I'll check when I go back to the yard tomorrow, I think they may have one or two training units there too, and see if I remember my ruler and get exact measurements if they have any off the trucks there.
I wonder why they change it them from being round?
Now to try and make these in scale
Not really sure Jonathan, but I do know that they operate through 3G cell signals now, not a satellite signal like older Qualcomm units used.
Also, as a side note, the unit most commonly hooked up to these new antennas is called the MCP200, and this is what the unit in the truck looks like on the home screen.
It also has onboard navigation, and this is what the nav screen looks like.
I will also remember to take some better pics (I was quickly taking them as I was cleaning out the unit I was driving at the time after a worker's comp injury and the company was on it's way to pick up the truck) and get measurements of the unit. I'll also make sure I get pics of the side of the unit and also with the slide out keyboard out and of the mounting bracket. One big difference between the pic and the way the screen of my current truck is that the "Hours of Service", the second tab not lit up on the left side from the top between the "Messages" tab and "Navigation" tab, IS lit on my current truck. That is how I do my electronic logbook, everything is recorded through that tab, and all fleets using electronic logs (to my knowledge) use the same unit and tab. No more paper logs, other than for if the unit malfunctions, and that is very rare.
