FYI - this is lifted from the Garmin website:

GPS users all over the world got an early present on December 21st. The United States Air Force launched the fifth modern NAVSTAR GPS satellite into orbit from Cape Canaveral Air Force Station. Other than adding new channels to the military side of GPS for better accuracy, the new satellites will also increase strength of the GPS signal and add a second civilian signal. The Air Force is in the process of updating the GPS satellite constellation.

Also the FAA recently announced that WAAS signal is now active in Mexico and Canada.

That's good news! My lil' Yellow Etrex can use all the help it can get. God bless the USAF!!
