Hi all, I have a 97 355 GTS and have no idea what this knob does? Thanks for the help! Image Unavailable, Please Login
I have my fire suppression release knob in that position. In your case, the knob might be a volume control for a radar detector. (Turn your crossed flags badge around on your ashtray cover) . Image Unavailable, Please Login
You're welcome. For the K-40 control, the outer ring has three detents; center is OFF, left is CITY, and right is HIGHWAY. The center knob controls volume.
Now you can go and find where the front and rear antennas are located. My front one was bouncing around in the brake duct!
