GPS NEVER gets a lock!

[xxTouchFloxx]

ok, so i have upgraded my alltel vogue to the newest radio and i can still never get a gps lock.

i know with alltel, its gps enabled but not gps ready
in google maps when it says seeking gps satellites (0)...
it always says 0, i also have tried gps viewer and ive let it sit outside for 30min and it never gets a lock. is there anything else i can try

i have followed every gps tutorial on this site (ppcgeeks).

its starting to get very frustrating.
can someone please help me
