Garmin RV 760 vs Rand McNally 7720

I bought a Garmin RV760LMT not long ago. I like it pretty well so far. Only 2 minor complaints at this time after limited use: 1) The Tomtom in my car normally shows the current time, travel time to destination, and arrival time. The Garmin doesn’t show the current time (and the clock in the coach is on the radio, down between my knees and my ankles), and I don't think it shows the hours and minutes to destination, only the projected arrival time. Yeah, I’m wearing a watch, but I miss having it more or less in front of me. 2) The Garmin gives me an audible warning about a mile before each sharp curve in the road ahead. I live in West Virginia. If I am on a secondary road, it is forever warning me, sometimes 3 or 4 curves ahead. I wish I could turn off this feature, at least temporarily, but I haven’t found a way. I grew up in West Virginia and I know how to drive the roads without being caught unexpectedly by a sharp curve. The continual warnings are tiresome and a bit distracting.
