I did some research to better understand how a NAV system works. As I stated my location on the maps was accurate. It was the maps lack of roads in the area I was travelling that was poor. I have since written Pioneer but if I had it to do over I would buy a system that uses Garmin maps. My Garmin NUVI 855W had taken me to the same location with no problem and had all the roads displayed on it's map. My is not impressed with my expensive "upgrade".

While traveling home last night my NAV system would not recognize roads I was travelling on. It did recognize them when I was travelling to the destination. My GPS signal is somewhat weak. I don't understand the symbols which indicate one Orange and one yellow satellite icon in the GPS Ant status . I have 1 bar on signal strength. I guess I also don't understand the satellite data that is received. Aren't the maps internal to the unit? If so why would the maps display a road at one time and not another. My cars position on the maps appears accurate. My antenna is located under the dash pad abo
