Questions: I just ordered my GPS system and now into the mounting decision and I like your tube mount. What was the measured cut length of the tube that worked for you? Also, you mention a stronger RAM mount. I was considering the RAM B-201 connected to the tubing, with the standard B-238 socket arm up to another B-201 mount diamond plate to the cradle for the 1250 Nuvi. GPS city sells a kit (RAM-B-138-GA33U) that is basically this setup but instead of two - B-201 plates, they provide one B-201 with a B-202 universal round mounting plate (which looks like what you have connected to the back of your cradle). Is this the stronger setup you have? If not, could you provide the parts used in your setup?
To clarify, I have a Zumo and use components from that setup - cradle etc. I did not buy a separate kit.
I'm not even sure now if I did buy an extra part. It appears I took "RAM with U-Bolt base
" part and mounted it on the tube. I'm not sure which unit that came with as I have several.
The proof of the pudding for any of these mounts is if they vibrate on rough roads. The RAM ball is rubber coated so it provides some damping, but if the mount isn't rigid, the GPS is going to vibrate too much to read easily (not to mention any longevity issues). Before I got the Madstad, I mounted the GPS using the standard hardware to the plastic cover bracket that is under the stock windshield:
Once I got the Madstad, I needed a new mounting base. What you have is a mass cantilevered out some distance, so didn't think a bar or angle bracket was going to be anything like rigid enough. They were going to look fine, and work OK on smooth roads, but were going to vibrate like crazy on rough surfaces.
So I went to the rectangular aluminum tube. I tried to make everything as short and stiff as possible. It is a 6" long, 1" rectangular aluminum tube + base + short extension + the GPS cradle. It so happens that standard 1/4-20 carriage bolts are captured perfectly by the mount. I used nyloc nuts to hold it in place.
You can buy a couple feet of 1" rectangular aluminum tube for a few bucks at any HD or Lowes. I drilled two small holes to use the Madstad bolts, then drilled two larger holes on top to access them. Primed it and painted it with semi-gloss rattle can black.
The GPS doesn't move and is right where I want it.
Repost of front view:
I actually thought about having a batch fabricated and powder coated, but other guys were trying to sell their own mounts and I didn't want to rain on their parade, the market is very limited, and it will take you longer to go to the store and buy the material than it will to make this one.
