I picked up my first Blackberry yesterday (a 8320) and up to now love it, apart from one thing, the maps. I used to own a Nokia N95 complete with TomTom sat nav which was fantastic. I've tried to use my Blackberry maps but I am unable to turn on the sound to prompt my directions during my journey. And is it not possible to just type in zip codes or postcodes instead of the full address. This is really annoying me can anyone help??
