After downloading Navfree yesterday thought would give it a try on the way to work,

staarted off great Kate told me to turn right at the end of the road lol but a after I hit the home button twice for mix I did get the radio and the Nav screen but from then on no voice guidance,is this correct or has Kate gone Back to bed

On a more serious note if this is correct why would I not want music and voice directions,

I used a free version of Copilot with my phone and my basic Headunit before purchaseing the Appraadio and when Kate said turn left, the radio turned down automatically

navfree is not a very good app. Try waze. No, that is not working correctly. My waze does what you want perfectly fine. 

Except waze doesn't store the maps on your phone. It uses data as you navigate.
