The last few days, I've been having a problem both downloading data from my 735 (the laptop won't recognize it when I plug it in - that's an issue with three different laptops, so i think it's the Garmin), then the 735 won't go back to its normal mode unless I turn it off and restart. Then it takes a very long time to re-sync with the satellite when i next try to record something. Any ideas? Thanks.
