Garmin Suction Cup Mount for Nuvi 350
This is my third suction cup mount for my Nuvi 350. The first one that came with the product for quite awhile. I never removed the suction cup mount from the window and the sun and heat melted the rubber suction cup and it deteriorated. My wife has a Nuvi 340 and the same thing happened to her suction cup. I ordered a couple more.

The second one broke at the hinge after about 8 months of use. My wife's is still working fine.
I ordered a couple more. I have been using the new one for several months now and just returned from a trip where I used it in a rental car. No problems so far.

Just buy a dashboard friction mount
Every now and then, my Garmin would fall from the window if the mount didn't make a proper seal. Also, it would leave a ring on my window, which, in turn, could alert a would-be criminal that I have a Garmin in my car. I ended up replacing it with a Garmin friction mount for my dashboard. It works much better, and is legal in all states (unlike the window mount).

I got enough of this thing!
Ok, after getting yet another bruise on my knee after my Nuvi fallin down, I went online and ordered a dashboard friction mount. This Garmin Suction Cup that came with my Nuvi 350 works fine most of the time (90%?) if you put it properly. But when it falls it falls and this is not you want to be into when you are on the road.

I got it falling many times in 2.5 years but I was reluctant to replace it because I felt that I just did not put it carefully enough on the windshield. But I believe that any kind of a car gps mount should be fool proof to begin with and this thing is not, which is not acceptable when one's security is at stake.

The weak link in this mount is the flexible joint that permits adjusting the position of the Nuvi series up and down. The wall thickness of the plastic housing that encases the metal pins is way too thin and it doesn't take much to break out the plastic portion of the joint in sub-zero cold temps like we experience here if far western new York state. Thus my original mount broke out and I had to replace it with this one. Other than that failure I'd say it was a five star.

Great window mount!
I received this product 2 weeks ago to replace the one that came with my GPS. I installed it on the left corner of the window to not obstruct my view. Till this day the mount has not drop yet! But I know if I was to take it off and put it in another car then the suction won't be that great cause of the adhesive on the suction cup.
