I purchased a Garmin RV660LMT this summer and it works great. There are frequent updates available. It does not take as long to update as my smaller older Garmin did. You do need a USB connection to a PC though to do that.
The 660LMT replaces the 760 model. The 660 is a six inch screen and the 760 is a seven inch display. There were some smaller differences too. I thought I would go with the newer model
