Lots of folks seem to have a lot of concerns with upgrading he Verizon XV6900 to enable the built in GPS capability. This seems to be because many seem to think it's complicated and error prone, where it's really quite easy, due to the excellent info already out there. This walk-though is based on Darkflame808's "safer alternative"thread, and an attempt to provide easy to digest, step by step info.
Please be aware that, while easy to do and relatively robust, things CAN go wrong and you CAN BRICK your phone, so upgrade at your own risk. However, if something does go wrong, there is excellent advise available and you should be able to fix most problems.
The steps required to upgrade the phone basically follows the contents:





To turn your GPS ON:
Start>Settings>Phone>Services Tab>Location Settings>Location On
You should have GPS capability at this point!
Reauthenticating is required when you upgrade your radio. To authenticate your phone, REMOVE the battery for a minute. Then start the phone back up and dial *22801. Eastcoast users dial *22800.
