I purchased 2011 Buick Regal 2011 cxl turbo #7. since then, I have experienced serious difficulties with am/fm/xm stereo system with navigation and 40gb hard drive it is problematic, and it was challenging to get adequate directions, because of its poor quality of map data. A trip taken twice a year I felt a build in navigation system would be more secure and accurate. Road network attributes are contained in the map database the map database did not include data for old constructed areas or long term point of interest. This is a safety issues for the driver and occupants. I was given wrong directions and directed to far location when a closer location was available since updated information was not included.
