Can anyone advise me if there are, or could be, compatibility issues with installing & running a NH 262 GPS unlocked to RTK & NAV on a new model (2015) CASE 8240?  Software on both were upgraded last season i.e. 2014.  As long as it is fully configured & calibrated for the 8240 - should this be an issue?

Sales bloke is telling me: "it could be some issues"  but I'm sceptical.  I know the 262 won't have WAAS but that's not a great issue.

Thanks for the help.
