I have loaded the new maps 2012 as per fist post, everything loaded fine however once I took it out for a test run I noticed that my deck , z130bt, would map the road correctly but not give voice direction. instead it told me insufficient data for this area... I read other having the same issue but no answer to the problem. If you could help I would be grateful and to make clear I have read all post thus far. If I missed a solution your direction would be great. thanks all and great site. by the way I used the auto method for the update as per this thread.
