Long story short, purchased a Gen1 20/20 to add to JD7000. 
My goal is to monitor only, no controlling (row shutoffs, variable rate, etc) of any type, and I don't care about mapping anything either.
My Gen1 came with Precision Planting "Hockey Puck" GPS.
Local PP dealer says hockey puck GPS no good and causes lots of issue (blames it on 5G towers).

So to eliminate the hockey puck GPS, I've got a couple different GPS systems (either Raven 210 or 310 ... have one of each) that I could possibly use to feed GPS into the 20/20 if possible.
PP dealer says any GPS feeding into PP must be 5hz or greater, and that 1 hz GPS won't work.
No radar on planting tractor either.

So a couple questions:
1) Is Raven 210 or 310 running at 5 hz or greater (as I know they've got some age to them)?
2) Anybody out there attempt communication with this Raven into PP combo?  And if so, what cabling needed?
3) Is the hockey puck GPS, as bad is he's making it sound (at least for a monitoring only situation)?  

Thanks in advance for any replies.
