windshield obstructions

I actually did take a look at the GPS radio for an 05 Dodge but it was a couple years ago and pretty pricy. And the GPS wasn't RV specific. I once saw a mount that attached to the dash and could be flipped up if not using, it laid flat on the dash screen side down, and flipped down for use where the top on the screen was about even with the top of the dash. It took two screws to attach it but that's not an issue as my truck is an 05 and the resale wouldn't be hurt much. Trouble is that's the only one I have ever seen. We are getting ready for an 8000 mile 15 state trip in the spring. Lots of states I have never been in and don't know their enforcement policies.

I used a bean bag mount (before I got a truck with built in GPS) and set it on top of the dash just to the front/right of me. Easy to see and reach. And it only blocked a small part of my view of the lower right side of the hood, did not block my vision of the road at all.
Don't know where that falls in regard to windshield area mounted devices and the laws. But drove in many states with it and never stopped.

You should have looked into the factory GPS radio. But if you mount it in the lower left corner of the windshield I would think you you would be okay. Mine only has a 5" screen so its not an issue but with a 7" screen you might get some looks.

To me the bean bag mount blocks less windshield area, and yet is quick to see, if necessary. I try not to look at it in congested areas, and try to rely on the voice to keep me in the right lane.

I also went with the bean bag concept

Bean bag mount works really well

If you mount it either high up in the windshield where it wouldn't obstruct your view of cross traffic or pedestrians, or low enough in your windshield that it only obstructs your view of your own hood you should be fine from the obstruction laws.

Since you have a 5er you won't really be using your center mounted rear view mirror. I might suggest you remove the mirror for this trip and place it there, or else lower the mirror all the way and attempt to mount it above the mirror.

My wife has a Garmin 5" GPS that has a ball mount system. It came with a suction cup mount. I was more concerned with theft from my vehicle by having the tell tale suction cup ring on my windshield. We found a weighted mount with the ball mount meant for the GPS and can either place it on the dashboard or the center console. I prefer that method when we use the GPS.
