I've switched to a universal phone mount. The one I'm using is the Kenu Airframe, which is stone cold awesome. Easy quick one-handed mounting and removal of the phone and it holds securely.

I've attached the Kenu Airframe to the dash by:
1) Installing a Garmin-style sticky back ball mount to the Passenger Air Bag display area:

2) Cutting off the excess portion of a regular Garmin Nuvi bracket and gluing it to the back of the Kenu with some epoxy:

For the GPS, all I did was buy a length of thin steel bar from Home Depot, then cut off a section about a foot long. I bent it into shape and used a pair of small bolts on each the top and bottom to affix it to the cubby portion of my stereo's dash mount. The GPS is attached with mounting tape.
