"For a couple of months I’ve been comparing these two traffic sources in the Atlanta area with a nuvi 660 (TTN) and a 680 (MSN Direct)…
Well here, MSN Direct obviously uses more of the traffic monitoring stations than TTN, resulting in a more-detailed display of changing traffic conditions… As for "reality", MSN Direct also seems superior…
(Not to mention that you also get Gasoline Prices, Weather Forecasts, and Movie Schedules (not available with TTN) for $50 a year as compared to $60 for TTN)… And pardon for "beating this dead horse", you get one year trial subscription with MSN Direct as compared to three months with TTN."
I wish I could verify this, but I live in a rural area, and the only time I get to test traffic receivers is when I go to the city with a review unit. I will say that my experience with MSN Direct has been superior to TMC services, though I’ve only had the pleasure of trying out MSN Direct on a nuvi 680 for a grand total of a couple of days.
All of this comes with other caveats as well. While there are MSN Direct and TMC coverage maps, that doesn’t mean you’ll have coverage in the areas shown. Neither service works for me in Sonoma County, California, even though the southern part of county is shown on the maps. And the technology behind the various services continues to change.
Jack didn’t get many responses to his post (just mine so far). I’m curious, have any of our readers tried both systems? What has your experience been?
