Originally posted on MABDR thread & redirected here- Having some trouble with the tracks for this BDR. While loading into my GPSMap 478 got a message saying "Tracks truncated". After download each section has a gap before the next section starts? Anyone else have this happen? Is it a capacity issue? GPS was wiped clean before the download so I thought it was good to go? I've used it before for multi day track rides, but come to think of it the tracks were loaded each day. Any ideas? Obviously I'm not a tech whiz, so if there is a way to get all tracks loaded up on this unit please be as in depth with instruction as possible-Thanks for any help!
