We've run across a few GPS units with the "Error Parsing Waypoint" message when trying to import a .usr file. By updating to the latest software version, you can eliminate this problem. If a software download isn't possible in the field, a quick option is to convert the file to a GPX file instead of .USR. Keep in mind converting to GPX may remove some features like icon selections.To solve many GPS issues, we recommend the following versions of software:Elite 7 TI: 18.2 or 5.0Elite 5 TI: 18.2 or 5.0HDS Gen 2: 2.5HDS Gen 1: AnyHDS Gen 3: 18.2 or 7.0HDS Carbon: 18.2 or 4.0After downloading the file, copy the unzipped files onto a blank SD card (not the card with the mapping). Power off the GPS, place the card into the GPS unit and turn the GPS on. Call us if you need additional help.
