The update rolled out based on the device geo so with mine the latest one is 6.04. Maybe you can ask the mod/admin to check yours based on the unit ID.
Software versions vary by region. If Garmin Express states your device software is up to date, your watch is up to date. The number may not match what is posted on the Forums due to the region you are based in. However, if you would like me to confirm whether your watch is up to date, please reply here.
