different from the satellite network your phone is using for GPS
wayno wrote:teh satellites for your phones are far more prolific, but the garmin should still get a connection if you have a clear view of the sky, just not an instantaneous one, but it should get a connection after a few minutes... the SPOTs are worse you can wait 20 to 30 mins for a connection with those, they use a different satellite network again... try connecting with the buetooth off to start with

There are times when parts of Tasmania may only have one satellite (very rare) but only two is quite common. It may well have been in one of those cycles that you were attempting to get a fix in a poor location. Its no excuse but it may be the case.

Its always hard to tell with Garmin as they never quite give you all the information....
