[CA] [CA11] Ray52 (GPS) and i70s Integration

[liquidether]

I have a Ray52 VHF radio that has a built in GPS receiver. I also have your i70s instrument display recently purchased which can display GPS coordinates (shows it doing so on your product page). However, although both are connected to the same network the i70s does not seem to be receiving any GPS data. When I do a "transducer" search only my D800 and wind vane pop up—no Ray52. Is there a boot order I need to follow or a hidden menu somewhere?

Possibly related, my Ray52 is a bit older and has software version V1.31. It's possible the i70s needs updating as well although I just bought it. How do I go about updating the software without an MFD if software updates are the solution? I do not own an MFD.

Thanks much.
