I travelled across Canada this year.
I also went South to Tennesee to ride the "Tail of the Dragon".
In all it was about 20,000KM.
I got lost(not terribly) a couple times, and spent far too long looking for things like campsites and Grocery stores.
A GPS could be your friend in times like those but $700 is a bit much!
I'm willing to forego the waterproof feature since I could get 6 for that price.
I got a Garmin 1350 on sale for $115 and built this cradle and mount in about 15 minutes.
Well, the idea took about 15 minutes.
The build was more like mumble-mumble hours.
First, have no fear.
I drilled and tapped holes in the top triple tree to accept the Delrin spacer. These holes go through thin parts of webs in the casting.
Cradle and spacer parts. The Delrin machined like a dream. If you haven't tried it, buy some for your next low temperature project.
Finished spacer on the bike.
Cradle on the spacer.
GPS in and on.
The fit is a tight slide, I will try it tomorrow, the extra aluminum to the left can be drilled for a lock if it tends to slide out but I really doubt it will.
It's not meant to be looked at while riding, I just need it handy for quick access in a lay-by or whatever.
Now I can find a McDonald's easily, if anyone hasn't tried their coffee recently - try it. I prefer it to Tim's, and it rivals my home roasted from green beans.
