I have been using BC now for several months on my laptop pc and Oregon 450 and have had great success transferring data (geocaches and waypoints) back and forth. Today I talked a friend with a 550T into downloading BC and the nightmare began! I brought in a GPX file from the PC into a list and added a waypoint then sent the list to the 550T. I foolishly did not check the 550T because I saw the progress bar move and the statement "data transfer successful" (or something equivalent to that). When we got out in the woods to do our geocaching her unit had none of the downloaded caches (fortunately mine did - but I had just used "drag and drop" from her pc to my GPX folder without using BC). When we got home I tried doing the transfer again - from the transfer icon - from the menu - from a right click of the folder - from a drag and drop of the list to the 550T internal memory. Every method reported success but the GPX file is STILL not on the 550T.
Any idea why this would be?
Just a thought, but this Garmin 550T has a problem with wireless data transfer as well. It will send or receive one file (or part of one file) and then freeze up requiring re-boot. I spoke to tech support about this a few months ago and they suggested downloading the latest firmware (I already had) - they said "do it again" - I did - same problem.
