First, I was jealous, since my GPS coords weren't there, then very frustrated after playing with the GPS menu for half an hour...then EUREKA!
I got it to work! Whoopee!
With my audiovox 9500, enabled GPS "ON" went into the DEBUG screen and selected GPS One.
Dialed 922 and got a radio station.
"debug screen" Function 00 00000
Select GPS One
and then after scrolling through many cryptic pages of values, finally on page 06 Titled "GPS ONE: LR" there were some obvious coordinates!
I changed the format on my Garmin GPS receiver to display position format in ..hddd.ddddd degrees, so I could compare the reslts for accuracy.
N XX.70491 degrees ~ +/- .00011
W XXX.11334 ~ +/- .00004
Cell phone read
Took both outside to ensure a more accurate reading.
Very close. Not sure the exact error in feet between the two readings. GPS was WAAS enabled with a error of about 17.5 feet, after some location averaging. Which means the GPS receiver stays on taking readings every second or so for as long as you want and then averages the result as the satellites pass by and provide more data to be computed, resulting in a more accurate location fix.
It appears the trick on my phone is simply getting to the GPS debug screen and reading the "position result" after calling 922.
What the heck does dialing 922 have to do with getting the coords? Why is there a radio station at the other end? Is this call going to be billed?
Thanks for enough clues to get it to work. I thought it was impossible to get any kind of longitude/latitude coords from my phone, since so many of the GPS menus had an error screen saying "Currently not Available".
Believe a new coords is taken each call, not sure if the displayed coords on the screen can be cleared, until another call is made.
Not sure how count (default 1) and interval (30 seconds) would change the results, if at all.
The phone coords seem to come up quickly and only once, being displayed on a "MT Position Screen" during the 922 call.
It appears No IP addresses or other settings need changing.
WORKS ON UNACTIVATED PHONES TOO!
Being in a hurry the spare unactivated AVX 9500 was set to analog only and forgot to turn ON GPS location, from "911 only". Got a recording and voice tree for accident reporting for the CA Highway Patrol...
Thanks again for the inspired work,
