Anyone offer suggestions for some decent accessories for this? I have a mount now that sicks to the window, but because of the arm it isn't very stable and while driving makes it very difficult to read and see the map on the screen while driving because it is moving around. I am trying to find a stable mount for my phone, plus something that maybe can charge it and being able to listen to music on my device through my car speakers, maybe handsfree option too if possible. Anyone know of this miracle product? Thanks!
