Only my 2792 an dezl 760 had sun shades built into the Ram cradles. There are some clip on ones for the 40LM and 50LM.
LINK LINK2 Not sure if they will work with the cradle.

The bigger the unit, the longer the moment arm, the more likely you are to have issues with it re-positioning. I use short ram arms and don't have this issue with the 40LM. The 2797 in a Ram mount w/shade needs a longer arm and definitely vibrates more, but once the balls takes a set to the arms, it stays in place with rare exceptions. Trust me, I hit plenty of bumps on the Scooter Cannonball from Bar Harbor, ME to Eureka, CA. Especially in PA and NY. Even snapped my luggage rack off and tossed my topcase down the road, but the GPS was fine. I won't say I never re-adjusted it, but it's not a constant battle.
For the Cannonball I preferred the larger 7" screen. Day to day, I prefer a smaller screen. I'm a visual guy, no voice in the helmet and speaker on mute.
40LM on my XSR700. Note the short ram arm.
