I've been using my HTC One as my car sat-nav for a while now but once I've been going for about an hour the navigation app just closes and goes back to the main car menu. I then have to go back into the navigation app and fill in my journey details again, which is a little tricky when travelling.
It does the same whether I am charging or not and I don't know why it is happening, there isn't any error message at all.

Does any one else have this problem or a fix?
