Opinions on Telenav?

I used it for awhile on my i830. Only real issue you may run into is
if you don't have a NEXTEL signal, the maps won't update.

Telenav is a nice substitute for a Navigation system but NOT a replacement. Like stated above, if you don't have Nextel signal the maps will not update. I have never had a problem with Telenav until the day i needed it the most. I used to drive around playing with it and it worked like a charm. Well oneday, I was in Austin TX, (i hate austin) and I was looking for this girls house i met on the net. Well on this day, Telenav was making my i730 freeze. I had to pull over, take the battery out and go from there. Just one of those rare cases. Other than that i love my Telenav
