I'm using the 2720 with the traffic receiver. I find that it works great. Much better than my wife's factory nav in her Infiniti.
If I get a chance I'll take some pix, but I'm swamped these days.
Go to gpspassion.com and you can find a whole lot more on the forums there and some pix.
I also like the fact that Garmin continually releases software updates that really improve the unit.
