I'm interested in hearing long-term updates. I've been attempting to run my phone (Virgin Mobile Galaxy SII) as a GPS instead of shelling out for a Garmin and I've been having terrible luck. Charging is the main problem. Shorting the data wires did not improve charge rate. I'm running a Burnsmoto USB port wired to an aux fuse panel. I think the vibrations from mounting to my handlebars (RAM finger grip type mount) have loosened the usb port on my phone. I'm skeptical about micro USB being viable for long term durability, but hope you guys can convince me otherwise. I'll probably be upgrading to a SIII within a few months, and hope it will work out better than my current phone. Definitely trying to avoid the $$$ of a garmin.
