I bought my D3 used and picked up the Nav disc from SWDW and everything works fine until I try and do a POI search or an address search. It won't let me do either of these options. It won't even let me click on them, and this is with the Nav disc in the HU.

Any ideas why it is not letting me use these features?

Yea, pull the parking brake. You also might want to read the manual for easily answered question like this one.

I've got a Bypass hooked up, maybe the ground has come loose on it. I don't have a manual.

That probably a good guess. And the manual can be downloaded from the Pioneer site.
