I too have the RV660LMT model. Got it just before a recent 16 day trip. I too like it compared to my old Garmin 885 is the large screen. Lot's of information can be viewed at one time. And other features, like "Look Ahead" gives me a view of the next nearest gasoline station and rest area, etc.
One thing I had to cut off was the "sharp curve" warning. I was constantly getting a warning of a sharp curve ahead, when in fact, the road ahead was nearly perfectly straight. I turned off this feature.
All that said, there is one thing that has tried my patience with Garmin. My RV660 was new, but an unsold earlier unit which came with 2015 maps from the factory. A lot of updated maps have come along since then. Unfortunately, I can't down load any of them because the latest map release contained some bad low bridge info, so Garmin blocked it from being down loaded.
Since my new Garmin had never had any of the older maps downloaded, I can't down load any of the newer map downloads including the one just before the latest bad map download. This really "jacked my jaws", so to speak. At least Garmin should have put that note out to the general public.
If I'm still in the return window to Amazon, I may send it back, even though I like the RV660LMT overall.

I chose the 660 over the 760 because it does not require a hook up to your cell phone (therefore using data) to receive traffic info. It has a special power cord with the traffic antenna built into it. Very happy with our unit.
