Dear Garmin 
Just bought a new gpsmap 66 st - trying to install the update - and keep getting same message - there was an error installing update 
its really annoying 
What I need to do make it work ? maybe refund it to the vendor ?
								
				
				
		So you're saying that these few posts covering diverse devices that I collated from these forums and some additional evidence from logs whilst encountering and investigating the issue myself do not convince you that it's actually GE that's broken (again)?
