downloaded v438.11. Reinstalled VZNAV, done bat pulls. Same problem. VZNAV works once, the chokes on aquiring satellites.
I have never had VZNav work a second time after I closed it. I think VZNav is flawed. If I'm out and about and using my VZNav during the day, I just leave it open in the background and don't have a problem using it several times. There are not many options on Nav systems if you a member of Big Red.
I've held off upgrading to a 5.0 hybrid because of the VZN issue. The cost/benefit of going to 5.0 just doesn't seem to be there for me. - Threaded SMS? - I just use Crunch SMS. VZN is too valuable of a resource to not work all the time. I'll probably jump to a droid in the near future, so all these OS limitations that Verizon puts on us will be behind me. Who knows, maybe the Droid OS has its issues too.
