I'm sorry but we don't have information on the delivery schedule of the update on any country or operator.
If you went to Settings and then Phone Update and it tells you that there's no update available, it's unlikely that you'll be able to update the device when you connected it to Zune since the update is not yet available at the first place. The best thing to do is to wait until the update becomes available.
Once you connected your device to Zune, it will automatically check for the updates. On Zune, you can also go to > Settings > Device > Update. You can read more here: http://www.windowsphone.com/en-US/How-to/wp7/basic
I have recently bought a lumia 610. I have updated to Win 7.8 and still have the problem people are reporting of drive freezing. It finds the location and plans the route but never starts navigating. Any suggestions?
Same problem with my Lumia 920. After a half year it now freezes since a week., plans a route but does not start navigating
I have done resets and uninstall install without any result.
After updating the phone and then doing a reset the GPS is finally working correctly on my lumia 610. I have noticed it can be a little "laggy" but otherwise seems ok.
The subject is quite old, but I didn't want to post another on the same problem. I have a lumia 610 bought in mid 2012 updated to 7.8. Now the problem is that Nokia Drive just keeps freezing, regardless if Im in a moving vehicle or in a wide open area on a sunny day, it will not find my location, current heading or speed, let alone navigate, it does have GPS connection(i.e. not searching for gps) but 90% of the time the arrow just sits there. As far as I owned the phone Nokia Drive has never had an update, but at first the navigation was working relatively fine, and then it just stopped.. I did try to clear the app history, and I did uninstall/reinstall Drive, and I did delete and download again the map/voice combination I was using. but the problem persists both in GPS/A-GPS mode.
P.S My phone location is turned on.
