problems with garmins not staying put on the dash in GPS technology and devices Posted March 3, 2011 · Edited March 3, 2011 by lostinjersey I have 2 garmins for the car, a garmin nuvi 1200 and a 765T. I've had them both for a year or two and they both suffer the same problem: after anywhere from 5-30 minutes the suction cup comes come lose and it crashes to the floor usually hitting the cup holder. I've had replacement balls, suction cups and and flat pieces that you attack the suction cup to. Nothing works. I've used suction cup mount GPS for years and never in my life had problems. I know how to correctly attach it. So does my wife. And now our GPS are practically unusable. I can't put them on the dash because I know it'll crash down and eventually break. I have to sit mine in the cup holder to use it.; thankfully its got audible directions so I can pretty much rely on the verbal instructions, but if I need to look at the screen I have to look far away from the road. I am wondering if any other garmin owners are having problems because this is too frequent to be coincidence.
