I'm thinking about adding a GTM 12 Traffice Receiver and subscription to my Nuvi 350, but would like the opinion of someone who has used the device and the service. Is it worth the money to add this?
I have a Nuvi 680 and it came with 12 months of traffic info. and I added another six months for $10. The few times I used it it was good and showed where the problems were-- I think if you commute - daily, it would be a valuable tool to avoid the trouble spots. They have a trial period when you sign up.
...on what your route normally is. I work in downtown Washington, DC and the traffic is not that useful to me. Very rarely will it give me updates of delays or heavy traffic on the route into town mainly becuase they are all on surface roads. The only time I get useful information is when I jump onto interstates and more heavily travelled state routes.
I did a two month temp, however, away from my home office and the traffic rocked! I had my choice of 3 routes to take and it always showed me which one was jammed and which ones I could take. Most of the routes were around the beltway (495/95) but it did help substantially.
It all depends on your particular situation I guess. If you could get a trial period to see how it worksout for you, that would be the way to go.
I used it with a Nuvi 660, and got hooked. As the others noted, the traffic data is tied to major highways in major cities. The data comes from TMC, http://realtimetraffic.net You can check the site's coverage area.
I am currently using a Nuvi 680, which uses MSN direct. Personally, I like the traffic data from TMC (Nuvi 660) better that the traffic from MSN (Nuvi 680). The GTM 20 (for Nuvi 660) connects to traffic (in my area) within 1 minute. The GTM 21 (Nuvi 680) can take up to 30 minutes to sync with MSN to get the traffic data in my area.
In short, I would recommend the GTM 12, provided the TMC covers the highways you normally travel.
