I purchased these units and have been trying to read up on them, but I'm not sure which units they are. I did call GRT but I think they are kinda busy right now as I have not heard back. I don't know if these are Sport, Horizon or what I might need to purchase to get everything up and running. I'm planning to buy the ADS-B package and the EIS package from GRT to go with these.
