My new favorite spot for mounting "light weight, 3-4”" GPS unit is left to rear view mirror This spot offers several advantages
► It’s natural for us to look into the rear view mirror. The location is not “new”, Experienced drivers don't have to alter normal driving habit.
► Eye level peripheral vision is not block. I mounted my GPS on the high side (to flush with the bottom of the rear view mirror. The normal out looking vision remains about the same.
► Easy reach for enter info - change setting while driving (it’s neither recommended nor encouraged). The location allows you to use peripheral vision to stay on the road, while performing tasks on GPS.
► This location also offers the shortest distance (out reach) between you and the device The outreach distance is actually shorter than mounting the device above the dash board.

Here are some popular spots:
▼ Upper left comer - mechanics leave oil change reminder stickers here. I think the position is less obstructive toward outward vision, but it takes your eyes off the road quiet a bit.
▼ Lower left comer - the inspection and registration stickers are located here. Many of dash board instrument pods often protrude in corners and blending into the A-pillar, making the GPS mounting point more close to the middle of the dash board. Then GPS takes up/(blocks) my peripheral vision for normal driving.
▼ Above middle of dashboard - I think this spot is similar to most OEM/In-Dash GPS receiver, but either the mounting suction cups or GPS block the large portion of outward vision. Some cars are worst than others, depending on the type of the vehicle (slope of windshield). GPS units can also set too far back, making operating and reading GPS nearly impossible
