I'm running xv6900 wm6.1 with customizations, valhalla, google maps
Valhalla users
Change HKLM\Software\Valhalla Legends\GPSServer\Mode=0, (from2) then soft reset
This is what mine is GPS works; at my desk-inside-4 sats Does take a couple minutes for first lock
Without Valhalla (fredcatsmommy's changes that spetrillo mentions)
HKLM\Software\HTC\SUPL AGPS\EnableAGPS = 0 and HKLM\Software\HTC\SUPL AGPS\GPSMode = 1
