Mounts for GPS or Cell Phones

[Ebuddy]

I've been scouring Amazon and Ebay and I've seen a few different options for mounting a cell phone or GPS unit (in a waterproof case), but none seem to be applicable to my MC-54-250 (Jonway YY250T). Either they mount on the handlebars (where I don't seem to have any extra room) or they're designed more for a motorcycle. I don't have a whole lot of space. I was wondering if anyone here had some ideas before I try to MacGuyver something.

Currently I have a TomTom One that I can use. I'd be happy to use my cell phone, but I need to be 1000% sure it won't vibrate off or get wet in the rain.

I just bought this one on Ebay for my Buddy 170I

It works ok, especially for the price since there were much more expensive options. This one fits under the bolt that tightens the mirror down. I can't get my gps mount to click in the whole way, but it holds it well enough. I do love having GPS, i set it on avoid highways and it's shown me some really cool roads in my area that I had no idea about.

I just broke down and bought a cheap GPS and just got that case for a 5" screen but the one that mounts to the handle bars.
Doing a shake down run this AM.
Leave for CON on Wednesday.
