Phil; I am awaiting Marc's answers as well, because I am trying to learn about the new GPS'es that have "LIVE TRAFFIC".
From what I found so far, Live Traffic comes to your GPS via your smart phone's data link and then to the GPS (probably via Bluetooth). Garmin and TomTom offer GPS with "Live Traffic" capability. For the Garmin, it needs to have an App called SmartLink on the phone. Here is Garmin's description.............
Garmin Live Services available through the Garmin Smartphone Link provides the most up-to-date information to your Garmin navigator. Some services are included free when you connect to Smartphone Link. Other services are available through a one-time in app purchase that offers premium content and enhanced features
The App is free at...............
I am not sure, but even with the App, Live Services might have to be additionally purchased. With this App installed an running is what is probably meant by syncing (IMHO).
My vintage GPS gives me traffic via a built-in FM radio receiver. If you are in an area without FM reception, you do not get it. Live Traffic is via cell towers, where there are many. I guess that is an advantage.
Besides how the GPS gets the traffic, just how is the traffic data acquired in the first place? I have found that Google Maps Traffic to be spot on. I figure that individual car motion is being monitored by tracking the position of your cell phone and your position movement. This I believe is how Google gets such fantastic accuracy. More then likely, Garmin and TomTom are getting their Live Traffic the same way; maybe not by themselves, but by through a service (Navteq?)
Hey Marc, I am still looking for more info if you have, because I am trying to decide in a GPS purchase.
