Hello everyone. New member. Located in South Florida. This is my first CTS. I am driving an Olds Aurora but giving that to my son who turns 18. My CTS is 05 with14,767 miles purchased used. 3.6 with 6 speed manual. Black on Black. :alchi: I take delivery this week. Any advice from anyone? Also wanted to find out if it was possible to replace current stock radio and upgrade to the DVD navigation system without to much heartache. Thanks and I look forward to talking to everyone.
