Check your coverage map. I know it sounds stupid but you would be suprised at how many people actually are in known trouble areas, in extended network, or even no service areas. If you recieve EV and your phone normally states verizon wireless then you should be OK for coverage

This has been happening with few 6800's that have been flashed. Time to go over basic trouble shooting. Naturually your location has been turned on is mostly likely working fine (GPS wont work correctly with WiFi since gps has a hard time IN buildings (particuarly with this model phone as experience by other carriers aswell) and will need to have Pay as you go Data 1.99/mb or a PDA data plan 44.99 feature for unlimited data.) If block is on the account then block is in the system therefore not even your wifi can bypass it. As said before it does use Sats AND towers to use VZNAV (NOT GPS. A-GPS) as other programs use only Sats (regular GPS) to have you located.

Your data connection is down at the moment due to the fact that your settings in the system are not properly validating. in the handset you are going to want to redo your settings by putting in your username password and making sure the connection is still dialing #777 (username = Yourtelephonenumber@vzw3g.com, Password = vzw (lowercase)) Powercycle Handset and see if your coverage is stating EV (check rssi also and make sure its got a good signal (-85 and lower = best) try to send yourself a mms from the phone to the phone itself (i.e. to your number) (to see if you can send and receive)

If you still cant connect then the dmu key reset mentioned earlier is a great idea. Sometimes that will push it through. Once connected to the data then you will be able to officially use your vznav but to make sure that it is not currupt Uninstall and reinstall the application to make sure that your version is up to date with no bugs or interuptions (i.e. no phone calls..)

once powercycled the phone should be good to go from there however you are going to want to make sure that the phone will be able to recieve phone calls (this rom should normally keep its Akey but just becauce of past experience you would want to check anyways.) #832 is VZW official test call. If able to hear test call succesful then you can make calls ...try to recieve one from another phone as well (MAKE SURE TO PLACE TEST CALL FIRST OR YOU MAY NOT BE ABLE TO RECIEVE AT FIRST AS PHONE WOULD NOT HAVE REGISTERED CORRECTLY) if you recieve an Authentication error then Call VZW technical support and ask for an AKEY (they dont mind giving it to you for free) once Akey is programmed and the phone is making and recieving calls and your signal is showing EV (bars dont normally matter but the RSSI number does. Make sure to View it again to see if its -85 or lower for the best result) You should be good to go to try and use your vznav. If still recieving error possible reflash of rom may be in order or even an exchange of handsets if THAT fails.

Downsides to VZNav is that you will not be able to use in all areas of the united states. Your maps wont download nor will your gps track in no service areas. Also your maps wont download in Extended Network(roaming) areas however you can still use the program IF YOU STAY ON COURSE so it doesnt have to reroute and redownload maps. If your Plan is Pay as you go then you will gain charges from downloading maps and using the program (I.E. little data charges if you stay on course. Bigger ones if you head off course. If you recieve a phone call your VZNav may stop working depending on how long the call is and how much you drive off course (Voice over data for pda/smartphones so your data will give way to stay connected to the phone call)

Make sure the feature is added on your account and that nothing else would disrupt the program (i.e Low memory or programs running in background.)

I have more but ime tired of typing. If any further questions just post and Ill try to answer.
