There is no need to have the radio on.
When you switch on the radio will always work but what I do is switch on BT (blue tooth) Radio will be off and then you can switch to GPS or when it is already running push the button on left above the screen to switch to the GPS. In set up you can adjust the volume and also arrange that the volume increases when you drive faster (more noise) If you want to switch off I always use the remote control because the gps does not need to go through the full start up procedure but starts immediately.
I hope this solves your problem.
