Hello group. I’m coming to the end of my rope with this and am really looking for help. I have an 02 Seville STS that I only drive in the summer months. I haven’t driven the car in two years and decided I want to get it out again. Put the battery in and the navigation radio gave me the wrong disc insert the correct disc error on the screen. All my research has led me to need the firmware disc 19115256. I have expelled all my area dealerships(4 caddy dealerships in total) and a lot of other things as well to find a disc. I’m asking all you fellow caddy lovers for help. Does anyone have anything that could help me, really wanted to drive the car this weekend on an Easter family trip. Thank you all.
