I have a Kenwood DDX7019 (http://www.crutchfield.com/App/Product/Item/Main.aspx?g=168550&i=113DDX7019&search=DDX7019&tp=75) in my Yukon and I am going to add the NAV (http://www.crutchfield.com/App/Product/Item/Main.aspx?search=KNA%2DG510&i=113KNAG510) unit. Can I use the same power and switched power for the NAV unit as I did for the head unit? Or do I need to use a separate power source?

if it's 10 amp or higher I don't see a problem with that. check the nav specs I'm sure they don't draw very much.

That is what I thought too. I think it is a 20Amp fuse but I will double check. I know it is more than 10Amp.
If it's a newer Yukon, I would use a separate power source. The radio may not be the only thing powered by that fuse and the wire isn't sized for additional load. If the nav unit plugs directly into the head unit and does not have a separate power lead, it should be fine but if you add the current ratings for both pieces and it's close to the fuse's rating, use a different source.
