i have helplessly tried every resource possible from Garmin for blackberry, to Topoexplorer, MGMaps,Waze,Amaze,..GPSWatch to name a few well known as-well as not so well known software available on the internet..... but the sheer convenience of a true offline voice navigating application is still a dream for us blackberry loving brethren
keeping in mind that us blackberry users are getting shortchanged when it comes to nav service, however. those using non-bb phones get the latest navigators to work offline ,they just use apps like garmin or oviMaps and store maps in their sd card!!!!
why cant we do the same
