GPS revisited

[Lorenzo1950]

I have tried many locations, and I don't use the suction cup window mount.
I use a bean bag device that sits on top of the dashboard.
The best place is directly in front of me on the dash.
The biggest problem I now have is the distracting glare of the GPS on the windshield at night.
Is there any way to resolve this?
If I move the GPS forward, the positioning of the glare on the windshield is not quite as bad, but I run the risk of the GPS sliding off the dash into my lap or on the floor.
I have heard of others mounting the GPS on the steering wheel but how do you attach it? Do you use the round plastic disc and stick it to the steering wheel column? Please, if at all possible, give detailed instructions so I can give it a try. Thank you.
