I have a palm treo 680 and I just downloaded all the softwear. I tried the unit this past week and imported my first trip. It was a 4 day but the importer turned it into a 5 day with nothing happening on the 1st day. Also in the trip id slot it put the date as the trip name instead of the trip number. Everything seems to be offset a little and I'm not sure how to fix it. It also would not recognize different time zones and calculate the correct times, example: leave IND at 0700 - arrive ORD 0710, block time and actual time should equal 0110 but it showed 0010. I went in the airport list and added the airports and appropriate time zones but it still would not calculate properly. The learning curve seems a bit painful with this thing.
