[CA] [CA11] Help with system integration on my sailboat

[Awakening]

Hi all,
Presently these are the electronics on my boat;
ST 60 Tridata
i60 Wind
P70 Autopilot (have old ST60 autopilot)
RC435 GPS

First thing I would like to do is to be able to get the true wind on my i60 instrument. I believe this can be accomplished by installing a E22158 converter between my STng bus and the tridata instrument. Please let me know if this is correct.
The second thing I would like to be able to do is to get the autopilot to navigate to a waypoint. Just wondering if I can accomplish this by utilizing the old ST60 autopilot to convert the NMEA 0183 data from the GPS to Seatalk and adding this to my Seatalk bus, which in turn is connected to my STng bus.
I hope this makes sense to someone out there. Also I am not against purchasing a new(er) gps that may do this for me.
Thanks in advance,
Trevor (Awakening)
