Used maps navigation this weekend. Was listening to Groove also while navigating over Bluetooth. I was stunned that the navigation voice seemed to be using the high quality Bluetooth profile instead of making a "phone call". The music stopped, directions spoken, music resumed, all with no delay, no phone call, no cut off words. I was amazed, especially since for me groove music never automatically resumes after a navigation instruction. Unfortunately, the next day, it was back to the same old "phone call", delay, cut off words, no music resume again. Happen to anyone else?
