I have downloaded that for about 3-4 days, and I have to say I am pretty disappointed with this. Here is what my opinion is:
1) The worst, is that it does not have a "route summary". THeir so call route summary only give you ETA and total miles, but there is simply no way to know the actual route.
2) The re-route is quite slow. I can go off for quite a while before I was redirected.
3) Not clear which highway I should "enter" (N or S, E or S). Just say "Exit here" (actually, they use exit for entering highway as well).
4) No easy way to enter address. No integration with address book, unlike Telenav.
5) 3D map zoom out is very little, to almost useless. You may be able to zoom out for like a street or two at most.
6) IT seems like they now change their lifetime definition to 1 device. So, you are stuck with your 8800 if you buy their software. and we all know how much we like to change our BB when a new one comes along. This mean $100 every time you change your device. This probably is the biggest factor as I definitely don't want to spend $100 on a device that I probably will replace once a year.
7) Does not support 8100. I have emailed support and they say it is unlikely they will support 8100.
Some nice thing include the night-mode, which looks pretty cool. POI seems pretty updated and have lots of it. The icons shown along the map that tells you POI is pretty neat.
So, I am not happy with this. Telenav is much better (even with the old version). THe only thing I wish Telenav have is a lifetime subscription... THey already have a 1-year plan that is $99, but I think I am willing to pay $200 for the lifetime subscription
RIght now, I think I will go back to Telenav...
