I run 3 Insights and have been considering updating to the TMX-2050. I spoke to a dealer about 3 weeks ago. Data format and compatibility were my main concerns. He was going to do some checking and get back to me. I have not heard a word so I guess I know what he found out. A proprietary data format is a deal killer for me.. I wish these companies would get there head out of the sand and build a product that the end user actually wants. WAKE UP TRIMBLE.
