I'm looking for a case to mount my android as a GPS device. I find that a lot of cases require attaching off centre (thus taking unecessary handlebar space), or have very bulky clips that don't fit around the stem, (and anyway, I like to have my cyclecomputer on the stem) or on the top bar, which often obstruct my legs or gets knocked.
Has anyone seen a mobile phone case which attaches like the Garmin out front system? (http://www.amazon.co.uk/Garmin-Out-front-Bike-Mount-Edge/dp/B0096855IO) which looks like it'd do a good job of keeping the GPS at the right position for reading, without obstructing the operation of the bike.
Edit: Nexus 4, weather proofing needed! (thanks)
