I have a 2008 210 champ with 300xs Merc. I am installing new electronics and need to better understand the Megalink system, and how it works with the Actia bios guages. I am wanting to have the engine info displayed on my hds screen via nmea 2000. I know this is possible with Mercury smartcraft and a Mercmoniter guage, just not sure if it is possible with how my boat wired. I spoke with an engineer from smartcraft and he had no idea what the megalink was. That makes me think I have something other than smartcraft. Has any one out there run into this yet? Any help would be greatly appreciated. I will figure this out in time and post it here to help anyone else who should run into this. Thanks to all of you, this is the best site for info,and help, period!
