You can use Humminbird PC, which is a free download from their site. It's not fully compatible with the ONIX series, so you need to mess around a little. But it will do the initial conversion. You will lose your icons and groups if you try to use Humminbird PC with data that you download from your Onix. If you change the icons from the generic blue dot to anything else on your ONIX, they will be converted back to the blue dots by Humminbird PC.

Put your Garmin coordinates on an SD card and download them in Humminbird PC. Once you see your GPX data in Humminbird PC, you can upload it back to the SD card choosing to overwrite the existing data. It should then be in the correct format to be imported to your ONIX.
