nope
i havbe the 255wt w/lifetime traffic.
it's USELESS in DC area.
even when there's traffic, it wont re-reoute u till it's over a 15min delay.
and most of the time it's late w/the time.
the few times i was rerouted, i saw that the main route was cleared already when i drove on local streets waiting at red lights!
I have the Nuvi 760(not the "T" model) with a lifetime Clear Channel subscription. I'll have to check again but the last time I checked two years ago, my traffic subscription doesn't expire until the year 2075. :biggrin:
I live in the Baltimore area and traffic works excellent. Both going/coming to DC, Virginia, New Jersey, Pennsylvania, and New York.

That's because yours uses NAVTEQ traffic.
Clear Channel > NAVTEQ???
One thing to add...Traffic coverage highly depends on the area.
There are areas where Clear Channel has zero coverage such as Buffalo, NY; Knoxville, TN and NAVTEQ does have. There are areas NAVTEQ has zero coverage such as Chattanooga, TN; Charleston, SC; Columbia, SC and Clear Channel does have. There are areas where BOTH have coverage with Clear Channel having more stations which lead to better accuracy of traffic reports than NAVTEQ does. I speak this from personal experience since I'm in the Baltimore/DC/VA area. I have two cables. The 1st cable that came with my Garmin Nuvi 760 has a lifetime Clear Channel subscription. The other cable I bought on eBay about a year later for my aunt came with NAVTEQ lifetime subscription. I found Clear Channel to be much more reliable in my testing of both cables so I added a lifetime Clear Channel subscription to the 2nd unit which means it now has both subscriptions on that one cable.

All those "T" and "WT" models that came with free ad-based traffic come with NAVTEQ.
Maybe one is better off buying the cable but that would be completely stupid.
The cables cost $200+ on Garmin.com Pay the $20-40 premium by getting a GPS that already comes with a cable(LT or LMT versions) and add a $60 Clear Channel traffic subscription to that same cable if you want. Better than skimping $20-40 and paying $200 for a GTM-20/GTM-25 cable.
**EDIT**
Looks like they've reduced the price of the cables to $120.
