I just reread you post and I missed the part where you said you input locations, im guessing gps cordinates. MSN maps does not have that function. As far as using the birdeye view..it is located next to the tabs that say road and aerial. the birds eye view is the next one to the right. If it is over an area where it is not available it is shadowed. I hope this helps
