Hi, I have a 950XL
 
	Couple of questions:
 
	Does the altimeter & barometer require any internet connection?
 
	Do you think both altimeter & barometer readings are accurate? I cant really verify barometer but i see a variance in the altimeter sensor reading (-2.3m) vs elevation as shown by Wiki for my city 217m.
 
	thanks,
 
	Rishi
