How well do the Ram suction cup mounts adhere to glass (windshield)? Anyone have problems with them falling off? I have a Garmin Streetpilot III that I would like to use one with. Thanks in advance, Ron
unbelievably well. However, all suction cups can fall off. My old non-ram suction mount used to fall off anytime there was a significant change in the weather. Ie, if I parked in direct sun I would often find it on the floorboards. But when I got my ram, it has a very different mechanism that really pulls a vacuum hard on the mounting surface. Highly recommended.
Yes, under extreme temp changes it may come off. But it will not come off due to vibration. My old suction mount would come off once in a while when I was off road. The Ram mount has NEVER come off due to vibration.
The last time it fell off was after it had been on for over a year, I went up through a mountain pass to go snowboarding. The temp had over 20 degrees-- well below freezing. When I came back out to my car the mount was on the floorboards. It hasn't fallen off since. So it's probably recommended that you occasionally dismount it, clean the glass and remount it. But I never do that.
