Carter,
ON my system with a Vaspar ais and dedicated gps working with an ES7. The dedicated gps does show up as an alternative gps for the MFD. I don¡¯t have it function as such. I use the internal. But it did show up there without me doing anything special.?

Hi, folks,
?
I just finished installation of a Raymarine AIS-700 and the Raymarine passive GPS antenna, the GA-200. I have the VHF radio (a Standard Horizon GX-2100) also connected to the AIS-700 which has its own internal antenna splitter.
?
The GA-200 antenna is mounted in an ideal location high up on the dinghy davits with a clear view of the sky. Its cable is connected to the AIS-700, NOT directly to the MFD.?
?
The AIS-700 is connected to the Seatalkng network.?
?
I booted up the MFD and assumed that I would see either the AIS-700 or the GA-200 as an alternate GPS data source, but it only lists the internal GPS of the MFD.?
?
On the chart, the well-populated satellite list, boat location and AIS target list are all correct. Everything seems perfectly copacetic.
?
The MFD is a Raymarine eS98 running Lighthouse 3.
?
All the other data sources (wind, speed, AP control unit etc) are correct.
?
I checked and rechecked the GA-200 cable connection to the AIS unit.
?
I also disconnected the GA-200 cable from the AIS-700 and connected it directly to the appropriate port on the back of the MFD. Same result: the GA-200 did not appear as a GPS data source.
?
Before I start laboriously dismounting the GA-200 to test continuity, here is my question: is what I'm seeing (or not seeing) the result of the fact that the GA-200 is a passive antenna meant only to boost the signal to the internal MFD processor? So that
the MFD does not consider it a separate data source?
?
May thanks for patiently wading through this.
