I have gone through 2 of these suction mounts and need to find an alternative to mounting my Nuvi 350. I live in Ohio where it's sunny about a dozen days a year and the cheap rubber that the suction is made of melts to the windshield. Forget trying to move device to other car with suction mount. You have to literally rip the suction off the windshield. Then it's completely useless. Worked great, until I wanted to use it somewhere else. You might as well glue it to your windshield, or not use the suction mount when temp is over 60 degrees.
