Is there any...

Place to get more voices for the Nav III other than the Garmin site?
Is there a way to flash the Nav III so that it has the same software as the 2820?

I believe there are some male English voices now, but I haven't bothered to update my unit.

No - if you want an integrated MP3 player, you could consider the Garmin Zumo 550
