Narrative:
Photo mission north side of border. As the border winds through foothills I was north of the border when the G1000 warning sounded. I was in VMC and had a clear view of the mountains ahead and the valley we were following. The warning sounded so loudly; I was momentarily distracted. The tower was trying to contact me but I was unable to hear them over the warning; which I could not mute. At the same time the map screen went to terrain and made it difficult to see the border depicted on the screen. I concentrated on flying the aircraft down the center of the valley and climbing until the warning stopped. The border snakes along the valley floor. I briefly may have drifted over the international border. I turned north on continued on the flight. The terrain warning is not adjustable or mute-able. In a remote area it is not uncommon to be in a small plane in a valley with higher mountains around. This is not an emergency and the volume of the alert was so loud that is was difficult to perform secondary functions.
