Hi, I have done various experiments over the last few weeks with no problems whatsoever.
At lunchtime today, I went looking for a local cache that was eluding me and when starting up GN, I got the splash screen and the phone froze, needing battery removal. (Using 2.0.3 on N73 with Holux M-1000). After restart of phone, on the second attempt, after saying yes to request for use of BT, it froze again, this time with only the text and GPS bars in the two top corners showing, rest of the screen showing normal icons. (battery out again). Try number three was a repeat of try number 1. So was try number 4. Grrr.
I then used Nokia Maps - no problems. Tried Garmin MobileXT - no problems, Back to GN - also no problems?????!!!!
I know this is not much help as it is not repeatable. When back in the office I see that there is 2.0.4 - loaded that and again, no problems. Most confusing!
Anyway - maybe I will escape the problems as I have just got a new N82, yes GN is already on!
Thanks again for the great app. BTW: I found that pesky cache this time around with the help of GN. :-)
