Ok, Not a lot of interest here but if anyone wants to know in the future, I have figured out what is needed. You need to buy the navionics SIM card and load it with the region you want. The 2012 boat has the Medallion Viper 1 module. This is important as the Viper 2 card will not work. It is installed and it works fine but it does have limited data as compared to what is available with the Viper 2.
