If your on this blog looking for tomtom or older navigon ipa files, location specified versions or anything else please read through older post you might find more stuff you might need..
There is no trick to update from the older version your gonna have do a new install ie. removing older version
In the download link there are a list of files, the bottom one is just the app with no maps... and the other part 1-7 are the maps of all north american areas... If you have the old maps just reuse them because the maps have not been updated just the app...
All you have to do is open the .zip in winrar and add the maps you'd like (you know, the ones you've already extracted from the .rar file I uploaded or the ones you already have). Once done, rename the .zip to .ipa and add it to iTunes or your choice of installation.
or just use link 2 and download the entire app 1.4 gigs and install then remove maps with ssh or whatever you choose..
New things/improvements that I've noticed:
1. Google search under POIs, VERY convenient. I've run into the "can't access Google server" a few times, but usually it just takes a second try to get it working.
2. Now have the option to have music pause during speech function. It's called "audiobook mode." Great if you're listening to a book and don't want the speech to talk over the audiobook.
3. Oft requested written turn by turn list (however, can only be accessed after starting navigation).
4. Ability to "block" your route in measured distances. (not quite sure what the usefulness of this is yet)
5. Not sure if this is new or not, but I've noticed that as you're approaching your destination, a checkered flag will pop up in the area where the next turn arrow usually hangs out. This flag will have a tiny arrow next to it signifying which side of the road your destination is on. I still wish the voice would announce the side of the road as you are approaching your destination instead of doing so only after you've reached it.
I will be making a video soon....
