I recently bought my E46 316i and it came with an Nav n Go iGo 8. The system is from 2009 but the Navigation is up to date and very nice. When I connect it with bluetooth and stream music, it works very well, however when I need to use the navigation, the music just shuts off. I turned off gps sound and master volume of the GPS but it still doesn’t work. Anyone have an idea on how I can turn off GPS sound priority ?
