With some handsets when you get back into the car, the audio with route through the car automatically ... and with some you need to manually switch it. If you have a cradle, you can push the audio toggle button to switch between handset and car.
I did route the audio from the car back to the handset (iPhone) yet I still can't turn off the electronics (nav. screen, etc.). I have to end the call then I can turn off the electronics. I don't have a cradle/adapter.
