I've been an avid user of GPS receivers since they hit the consumer market a zillion years ago and have owned a number of them for use in most every condition one can think of. Verdict? Garmin lost the plot long ago. Been to their site to try and choose a GPS receiver within the past few years? An maddening mountain of choices, each with a tiny difference here or there, making it near impossible to pull the trigger on any one of them. Even worse, most of their recent receivers reliably garner less than stellar user reviews. And Nuvifone? How on earth did that thing live long enough to see the light of day? How many people OK'd that? What a colossal waste of time and resources. Then everyone was waiting to see if they'd ever remove the blinders long enough build an iPhone/iPad app. True to recent bad form, they finally push one out that requires a cell signal for map data. Useless.
And despite impossible to ignore computer market trends, Apple users remain a side note at Garmin. They can't even be bothered to turn perpetually balky & flawed RoadTrip or BaseCamp into one proper piece of mapping software for Mac.
If anything good comes of their purchase of Navigon, I'll believe it when I see it. Likely best case scenario is that Garmin doesn't take what Navigon has created and turn it into yet another of their misguided experiments.
I'd love to be proven wrong.
