I've got the latest iPhone app released by Apple.

I was really looking forward to the update.

New problems.

It tends to default to night mode no matter how many times I switch it. Still sometimes it works. Another time it was night and it defaulted to day mode.

Turn by turn voice directions. I had it for awhile now, and I have only gotten it to work with voice twice. I've rebooted, shut down, everything. The most I get now is a tone when it reroutes.

Another problem, is the app goes to sleep on a random basis. I will be driving along and the screen will dim if I notice it or be black. Have to hit home button again and slide on to use.

Just wanted to pass this info on.
