Hi:) I have 05 cts, I upgraded (installed) to the DVD nav system and HID headlights. Which was pretty much plug and play.:thumbsup: I had to add a few wires for both but was relatively easy. So I am now thinking of upgrading to the STS.:worship: Is there an option to upgrade the HID'S also? I hear they are only standard on the V8 STS's.:mad: Same for the NAV, Is it possible? THANKS :) GUYS!!
