Second, you will need to download the official Verizon ROM update found here.

You will have to click on the right where it says Software Upgrade and select Download Now.

Once you have downloaded the file, connect the phone to the USB on the computer and run the file.
**NOTE: The phone will need to have a 50% charge and it can take a while. Follow the directions that come with the install and you will be fine.

Third, you will need to install the cab file that is found here. Once the cab has been installed, follow the setting directions that are on the link below.

The directions for the setting is located halfway down the page and it is titled Verizon MR1 GPS Instructions. Follow these instructions and you will have GPS enabled on your phone while also having 6.1
