Shawn, On the Standard LS I have tried the 2 and 6 engine (4 Constellation) setups using the State RTN. The advatage so far is when in sketchy sky either of the two 4 constellation setups have more sats to choose from. When GPS coverage is weak, Galileo may be strong. But in general the two 4 constellation setups may work or may take a half hour to get through any verification, irregardless of the reported health of the networks. Do you think this will improve with the next software update allowing the long press selection menu to reduce the # of Sats in the solution?
