Wow that's a lot cheaper than I was quoted in Australia. (AU$3750 to upgrade Navigator with Jobcom Box) I gave up in the idea because of the price.

Is the upgrade and installation of the jobcom box something a dumb farmer like me could do, or does it take a lot of tech knowledge? Are there detailed instructions available on how to do it?

Wondering if I could buy the jobcom from some nice, helpful dealler in the US??  ;-)
