Thread: How to install any Garmin map on Iphone Garmin StreetPilot

bent622--it doesn't work that way; in layman's terms, /etc/hosts is merely a hostname-to-IP address translator. Since 2.3+ not only needs to talk to gold.garmin.com, but expects to receive a certain response from it--even if you could block by IP address, any of the features that need to dial home in order to work correctly will fail because the correct response was not received. If you try to block it in 2.3 you'll either get the "Unable to communicate with server" or the "Authentication error" message, depending on what you try to access.
