ST8002 with an E127

[Mike Rocheleau]

Two questions, I installed a new e127 on a new to me 2007 Legacy 32 Down-east Express.
I updated the Lighthouse software and created a route using the auto routing. I opened up the route and hit follow route, and i don't know how to engage the autopilot to follow the route.
My prior boat had e97s and a p70 installed at the same time in 2013 so it was all same vintage electronics.
The AP is on the network, as i can see the rudder position on the e127, which also begs another question, which is, can I place the rudder indicator permanently on the e127 display as a header or footer so it always displays, it is difficult to see on the AP head.
Thanks in advance!
Mike
