HB makes the steps a little more confusing or complicated but still it is relatively easy. Believe me, Lowrance knows how to do this but mentioning HB... well, they don't want to explain.
Assuming you have a computer/laptop or access to a PC, you will need PC Humminbird (it's a program) from their site. If you have your HB registered, then you can simply download it. If not, register and download PC Humminbird.
Load you wpts/trails from the HB card to PC Humminbird. Save file as .gpx either directly to the Lowrance SD card with the adapter onto the micro chip (it's in the adapter) or save directly to a file/folder on the computer (good backup) and then copy it to the SD card. Remove SD card from computer, remove micro chip from adapter, place in Lowrance unit and import the .gpx file.
It may sound complicated but it isn't. PM me your phone number/namem if you want me to talk you through it. I'm tired typing.
