Was out of the game for a while and about to get back in. I want to run both north and south, currently have 25f bin installed to receive both. What is the best way to update south TP's? If I install the latest 27f transponder list will this kill my north?, or do I have to make the changes manually? Don't want to install anything that will jeopardize my current setup.
Tks
