Will a navionics hotmaps premium chip work in an eagle intellimap 320?

[ck85abc3]

According to the website, the chip will not work in a 320?

However, I found the manual online for a 320 before I bought a used chip and the manual told me that it will accept all navionics sd chips?

Should I resell the chip or will it work in my intellimap 320?

Thanks.
