I hold it like a microphone - that also helps with the noise cancelling microphone on the back of the phone. And while I haven't had a lot of experience with GPS devices (the last one I used was a Tom Tom in the US) they didn't speak street names. But who can read street signs anyway - I would prefer to know when to turn and in what direction.
BTW I found a link to a site that tells you how to put your own voice (or your loved one's) voice in Copilotlive if you want to have a more familiar voice telling where to go!
