Just curious, why did you run the command cachepart?
Can you get a gps lock when in maps?

Started with the reinstall, and was somewhat distracted by my two year old

Not sure what that optional command does, but hopefully it will not hurt.
I can't get a gps lock period. Looks like the only location I get is via cell tower triangulation.
