Hi everyone,
I have an Aocci GPS that I would like to fit on to the Dash/Parcel shelf (see picture). My query is, is it OK to drill through this area for the bolts etc? The shelf is hollow as far as I can ascertain. Does anyone know any different?

Thank you in advance.

You would probably need to put some reinforcement underneath because it is not really designed to support anything.
Another thought would be to make a bracket that attached to the nearby screws and then attached the GPS to that.
That way if you don't like the position, you can move it with no harm and holes.
Years ago there were dash shelves built that did that very thing.
 
The shape of the top of the 1100's dash looks like it might be sturdier than that of the 1300 which is also hollow. I put a bracket on mine that used the two factory screws on the top of the dash. But they screwed into to tabs that could break if the screws were torqued too much. That probably needs more reinforcement than the dash itself. That doesn't look like a thing with the 1100.

Using a somewhat wide base to spread the load would help along with large diameter washers underneath the dash. Keeping the weight of the assembly down and centering in above the mount would probably be a good idea. A lot of mounts I've seen on the top of the dash place the ultimate location forward of the mount closer to the rider. This would leverage the strain on the mounting points.
 
I always think twice, or more, before cutting holes. What happens if you decide you don't like it and want something else like a Carpuride or a Chinese GPS like UP has? Just askin'.

Thank you "Uncle Phil". A friend has made me a steel platform that will secure to the dash (holes drilled ready, two to go through the dash and one for the mount of the GPS) to spread the load, really just a sense check that drilling through the dash is not going to be an issue.

The comment about the washers is duly noted - thank you!
I need to have it fairly close to the front edge (i.e. closer to me than the front of the bike) of the "shelf" due to the height of the unit.

Your description sounds like you are drilling holes through the dash as opposed to screwing in to the dash. Whether or not the below suggestion is needed will depend on how your platform is designed but if you feel that additional support is required to prevent the dash from being crushed when the screws are tightened you can use some tubing to prevent this.

- Rigid tubing the correct inside diameter to fit over whatever size screws you are planning to use.
- Cut the tubing to a length equal to the thickness of the dash at the location where the screws will be installed.
- Drill the holes in the dash large enough to accommodate the diameter of the tubing.
- Install the tubing in the holes in the dash.
- Install the screws through your platform and then through the tubing.
I like to find plastic tubing for this type of thing if I can because it will never rust and it is easy to cut/file to the exact length, and it is easy to shape to the contours of where it will be installed.

Thank you - what a great diagram.
Have attached a photo of my bracket (now painted, fairly close colour match). Am definitely planning on going through the dash, that's why I noted about the washers. Will see if I can find some suitable tubing. I guess only needs to be around 6mm long!
It sounds like the holes in the dash are going to be larger than originally planned (to accommodate the tube) and that the tube will effectively be touching the underside of the top bracket (mine) and the large washer beneath.

The two outside holes will go through the dash, the middle hole is for the screw that secures the GPS bracket to my bracket. It is pictured upside down currently!

Or you could leave the holes just large enough for the bolts (as originally intended) and place the tube inside the dash so the top of it presses against the washer under the dash.

The nut would tighten against a washer between it and the bottom of the tube. Would you secure the nut to some other part of the dash? That would help keep the GPS stable and help prevent it rocking back and forth.

If you find a not drilling option it would probably be a better way to go.
