Petri, I do agree with you whole hartedly, the problem however is (And I use them only for dialog) that if left to Trimble to do it it wont get done. If left for VW to do it they cant support every native format but us being end users should be able to request this of VW, and in turn they should contact Trimble on the matter with a request for joint or generic data, together they can make it happen they both win in this scenario which makes the end user the real winner. When One big company like Trimble jumps on board with VW then others will eventually follow. We then have simple solutions and we can stop this thread and move on to the next issue.
I know its a little bit of a rosy outlook but hey I'm a little tired and hungry.
As for .cnx the data recorder uses has many embedded features that seem to get lost in the malay of file transferring. I can only assume this would be better served working natively. It least I would have many fewer steps in transfer. Time is money!
