This is a repost from ADVrider, but figured I'd share it here since not everyone is on both forums.
I started looking for an above gauge iPhone 6 mount as I wasn't happy with the sea of options available for handle bar mount, my main issue was that I had to look too far down and take my eyes off the road in order to read the navigation.
The other issue was that solutions from SW-Motech/Ram/Touratech were in the range of $90-170, way more than what I wanted to pay for something this simple.
Here is my Frankenstein's monster:
1) Ram B-138U-C mount, purchased (used) on eBay: Cost - $19
2) Reserwa Bike Phone Mount with IP68 Waterproof Case for iPhone 7 360 Degrees Rotation Bike Phone Holder for Bike Motorcycle iPhone Bike bicycle Mount 3.9, purchased on Amazon. The iPhone 7 holder fits iPhone 6 perfectly, there is also an iPhone 6/7/8+ option for the same price: Cost - $7
Link to case iPhone 7 or 7+ its on the same page
3) Home Depot Screws: Cost - $1.40
Total cost of parts: $27.40
Step 1: Take off the windscreen, any basic set of hex keys will do
Step 2: Drill the holes that correspond to the size of the holes of the diamond base of the Ram mount. Mine came out a bit crooked but it doesnt really matter as the mount is adjustable in every direction so it has no effect on placement as you will see below. Also, I drilled with the bracket still on the bike, it seems very sturdy so i went ahead with it.
Step 3: Screw in the ram mount diamond base to the bracket with the Home Depot Screws listed above
The bracket and the ram mount arm are very sturdy, I do not foresee having long term issues with this setup.
