Screen blacks out after ending call while navigating

[y2k2]

While navigating and i get a phone call, the screen blacks out and doesn't come back until I hit the wake button. As if that's not bad enough, after the call ends, I would think that the screen should come back but it doesn't until I hit the wake button.

Are there any settings that would fix this? I would think that the maps and the phone would work a little smarter here.

Oh and also. I notice that when the phone call comes in, the stupid navi doesnt doesnt mute the voice. So if I'm engaging in a conversation, suddenly the navi talks and it creates a nice mess of a conversation. I would also think the voice should get muted while on the phone but I guess, not.
