Will any gm nav disk work in the 05 V? Or does it have to be sprcific for the car?:banghead:

No, any GM Navigation disc will not work in the 2005 CTS-V. The Navigation disc must be setup for the particular Navigation system that is installed in the car.

I have tried two differnt gm disk's plus one that was sent to me from cadillac and still nothing works..Maybe I have a bad DVD system?

If your unit plays a DVD chances are it is ok and you have an incompatible nav disc.

The CTS uses the same disc and the Zenrin 6.x series will also work.

You may need to upgrade the firmware also.

Click on Infotainment and Navigation on the left, then to... Is my Nav DVD out of date.

That should point you in the right direction.
