Recently got my hands on a Garmin Dezl 560 LT in Europe. (without lifetime maps)
There's quite a bit to say about this Navigator / GPS. From my point of view it's a bit of a hybrid - mixing truckers navigator (like the soopper) with a RV and Passenger Car GPS.
So far i like it - though it's a first release and has had 3 software version updates over the past 2 months. Best thing is the wide screen and loud speaker - so it can be seen and heard in a large driver cabin with a big engine. Also it's easy to use it in a car - which i think is a big plus, switching to car mode.
I wrote a few things about it, have a look:
