Question: Will it fit my garmin nuvi 3811?
Document: My Garmin Nuvi did not fit. The GPS was bigger than the holder. Should not say &#34;universal&#34; if it does not fit all Nuvi GPS's
I bought this unit because the suction cup on my Garmin nuvi 50 LM got stock to a hot windshield. This unit will not fit a garmin nuvi 50LM  it's to narrow. not a problem just use the  Garmin nuvi 50LM holster but the ball is just a tad to small and don't have enough grip to hold the holster with the garmin in to up. other wise the unit is well built and would work fine it you can use the holster that comes with the unit.
Bought as gift for brother-in-law which went along with the Garmin Nuvi GPS I bought for hime for a gift
This product is a lie. My family has a few Garmin Nuvi and this product had a good connection with just one of them. Its upsetting that you order something expecting it to be one thing but it is not what is says.
When I purchased my Garmin nuvi 40LM from Amazon I didn't want to have to remove the holder every time to switch vehicles. So I ordered a second suction cup for my truck. This is not a stick on or so called lick and stick type unit. It is manufactured the same way that units used for installing large plate glass windows work. It has a pump lever that can attach to most any smooth flat surface. I tested it on the windshield of my wife's car.
It seems to be fine, I haven't had any problems with it at all. Everything fit like I needed. I'd buy again.
My product arrived quickly and exactly as the listing described. This product fit my GPS perfectly, and is actually of better quality than the OEM part in my opinion.
The merchandize came very quickly. The suction portion's spherical part fits the old clip. But the new clip is for another model. The teeth that hook it to the GPS itself doesn't fit the GPS's body's perforations for them, making it useless to me.Thanks
Cradle did not fit my GPS model. First time I tried to attach the suction cup to the glass, the unit came apart. Seems that the suction disk was not adequately attached (glued) to the lever used to deform the suction cup on the glass.
it said universal but my garmin does not click in on bottom of gps and keeps on falling out of holder
Answer: I have used it and will work.
