Review: Great - Very good quality, does its job perfectly
Review: I found Ram mounts a few years ago and love them. Just purchased a couple more pieces - I found Ram mounts a few years ago and love them. Just purchased a couple more pieces, so my review is copy and pasted from my updated review from a previous purchase. RAM mounts are still the best mount I've found. Not going to find anything better. Very simple design that's brilliantly executed. I've never been satisfied with other options such as suction cups or double sided tape mounts. They'll all fail at some point. Then a few years ago I discovered Ram mounts. Made my first purchase and I couldn't have been happier. I've now purchased multiples of the 1" ball for camera mounting over the years for various applications. My most current usage was to mount a 6" cell phone on the dash of a 2012 Camry for Pandora/Google Maps. I wanted something secure and adjustable, yet easy to remove. Ram fits the bill. For this setup, I used the following products (I'll supply links at the end): Ram Mount 1-Inch Ball with 1/4-Inch 20 Male Threaded Post for Cameras Ram Mount 2 x 1.7 Inches Base with 1-Inch Ball Ram Mount Composite Short Double Socket Arm for 1-Inch Ball Part of a Vastar Universal Smartphone Tripod Adapter 3/4" Phone and Fax Plastic Grommet Luckily enough, my Camry has a large section of trim around the clock on the dash. The whole thing comes out very easily. I removed the trim piece and disconnected the clock from it. Marked out my holes for the 2" x 1.7" Ram mounting plate. I mounted the base plate with black bolts to blend in with everything. I also sandwiched a small piece of black rubber shelf liner to eliminate any possible squeaking. Whilst the dash is fairly flat where I mounted it there is a very slight curve. The 1" ball mount for cameras get attached to the upper part of the Vastar Universal Smartphone Tripod Adapter, the short composite Ram arm connects it all together. I also drilled another hole in the clock trim piece to run a USB cable in-dash behind the radio. I used the 3/4" phone/fax grommet to finish it off and give a professional look. I couldn't be more happy with how this turned out. It's very easy to use and it's something that can be quickly removed if I don't want to leave it in the car. The only thing that stays behind is the mounting plate that's bolted to the dash and the USB cable. I think car's should come with something similar to this. It's not far from eye level yet doesn't block my view.

## Questions & Answers

**Q: Is this plate compatible with a TomTom rider 550 motorcycle specific gps?**
A: This ball is universal and whatever the ball size of your gps holder need to match up to same ball sizes

**Q: How tall is it?**
A: Drawing indicates 1.49" or 1 1/2" practically

**Q: Can someone share with me an amazon link for purchasing the bolts and nuts i’d need to connect this base to a garmin amps mount ?**
A: Do not have an Amazon Link but your local hardware store should stock the nuts and screws for mounting this.  They are 6-32 X 1/2 inch if I remember correctly.  Many RAM Mounts also come with a selection of the required screws.

**Q: Any chance this will mount up to a proclips phone holder for my nexus 6p?   Trying to adapt to ram mount stuff so i dont have to use proclip dashmount**
A: Richard: The key is the ball size, and also, the mount hole location in the Ram Base Unit you are referring to. Not knowing what a Proclips Phone Holder is in regard to ball size and mount holes location, I really cannot say. However, if the mount holes do not line up, you can always redrill holes in the proper location to fit the Proclips. Or, you could clue the Ram Mount to the Proclips. I went to Amazon and looked at pictures of Pro Clip Phone Holders, but I cannot tell from the picture whether the Ram Mount Base is adaptable or not, nor can I really tell exactly what kind of mount combination you have in mind. Perhaps if you could explain a little more what your intentions are, then I could offer more help..........SHALOM......Brother Randahl

*by J***N on January 10, 2026*

Always excellent quality. I only buy Ram Mount products. They have always served me well. I Shoe-Goo these bases to back of car touchscreen. Always holds well. And never had a Ram Mount product failure in 15 plus years. And I've purchased many of their products.
