Information receiver updating
The data sent down to earth from each satellite contains a few different pieces of information that allows your GPS receiver to accurately calculate its position and time.
Because such upgrades require specific parts, these upgrades are only offered while supplies last. In the case of DVD players, it may change the region code which will leave the player unusable as our updates are for region 1 players. All you need is a GPS receiver, and receivers are getting less expensive and smaller every day.Don’t take these tiny, inexpensive modules for granted.All current products are able to download updates directly from the Marantz server using your internet connection.This would be initiated through the menu of the Marantz unit.
