Whose bright idea was it to put Zonar tablets in all of the trucks?

Ya, those docks can be a problem.
I went in to Gary a couple months ago to get mine replaced because it kept losing the connection with the tablet.
Gary only had one in stock, and they were not even sure if it was new.

 

They charge the companies arms and legs to operate with their systems, meanwhile they pay in peanuts to the manufactures.

 

All electronic systems have weaknesses.
With some it is the heat, others it is the cold.

My RM GPS just shows a scrambled screen if I turn it on when it is too cold, but the Zonar is fine at that temp.
