The latest versions of Toolbox do not let you change the "auto configure receiver on startup" setting.  It defaults to "on" on new installations.   That feature is turned off and we cannot turn it back on.  We turned it off with a T170 display, but we are now using the FMD display and it will not turn it back on.  We are using a nonstandard port setting on the B-Port to receive correction signals.  For that reason we do not want the receiver to be auto configured on startup.  I would like to set the receiver to auto configure and then turn it back off, but for some reason Trimble decided that we do not need that option.

 My dealer is working on the problem, but Trimble has been slow to respond to him.  The closest dealer is 200 miles away, so the distance is a problem.  We are trying to arrange to get his spare receiver and Nav2 to check for hardware problems.
