Bought a new 3330 Patriot sprayer this spring with Viper Pro. I upgraded to the Phoenix 300 and was told I could run both Glonaas and waas at the same time., therefore more availability of satellites at any given time. Now GPS tech at dealership says I can only run Glonaas with Omnistar ot RTK. Is he right or can I run Glonaas and waas at the same time if so how to do it?
