[CA] [CA11] E120 to EV100 autopilot

[Kingfish]

I Have an EV100 autopilot connected to a seatalkng network which is connected to my E120 seatalk2 port. The E120 is software version 5.52. Also connected to the seatalkng network is an RS150. The E120 is receiving position data from the RS150 but the EV100 is not. When I use the p70r to search for data input I get an error message saying the E120 is not compatible. The RS150 was installed to replace a Lowrance gps module that was failing. Interestingly the Lowrance module connected to the same seatalkng network was able to provide data to the autopilot. What do I need to do to get the autopilot to "see" the position data on the seatalkng network? I intend to update the software to version 5.69 but am not sure if this is the answer. Thanks for any help you can provide.
