[CA] [CA11] e7 not seeing AIS & autopilot

[kalakai]

I have the following:

e7 (v. 17.46)
E120 (v. 2.65)
P70R autopilot control head
ACU 200 autopilot actuator control unit
AIS650
ST60 depth/speed display
ST30 depth/speed display
RS130 antenna

All connected to seatalk backbone (I don't know if I'm using correct terminology, but all of the newer items are connected with a seatalk backbone cable, older units with the old style seatalk cable)

E120 see everything (depth, speed, AIS, autopilot control)
also sees GPS antenna from e7
e7 sees depth, speed, course/wpt info from the E12, but
does not show AIS does not see autopilot or heading

I posted on this over a year ago and got sidetracked, but am trying again to get it working. In the earlier post someone said I needed to go back to an earlier software version on the e7 for it to work with my AIS and autopilot.

So my questions now are:

* Can I make the e7 operate the autopilot?
* Can I make the e7 display AIS info?
* What kind of radar can I add that will overlay on both units (if any)?

or

do I just need to replace the E120 with a newer version to plays better with the e7?

I attached a few pics to the post for reference, but they will not 'insert into post'.
