I've been searching for an answer and finding various opinions so I thought I'd ask. I have an HDS 8 hooked to SS at the console and an HDS 7 up front. I want to share waypoints so I can find something at the console and see it up front while fishing. I don't have a NMEA box which I understand syncs instantly. I've heard that with Ethernet they only sync at startup. If this is true, is there a way to sync without repowering the unit? Maybe putting it in and out of standby or maybe through the menu manually?
Thanks.
