I also would have to say 'G-Nav' and positioning have been very good when I have used it. It often takes probably a lot longer than it should to lock on. Sure the routes can be a little illogical if you know the route and just want to get an ETA, but they used to be worse on standalone Garmins and TomToms. I started to use the Google traffic info overlay over dedicated breakdown service traffic apps. Mostly been a good guide to work a route around or through London. I know what @TXTGOU means about user input which would be better still if enough people supported it. Whacky routes you got, too. But your position was always OK right.
It was the insistence suddenly and over a week that I am in a spot in France that surprised me.
My first stupid thought (I get several
) when it first stayed on a false position, was of a possible connection to the search for the missing Malaysian 777. Thinking satellite resources were focusing on that region. 'Course they would only use imaging capable satellites to continue the search, but could they have collected old data from other satellites. There's a lot of them up there. Like I said, stupid.
But this has been odd behaviour, more so because I haven't heard it reported elsewhere.
