New post for me too and new member. Thanks in advance if anyone can figure this one out.2000 CLK 320. Turn car on and I dont get the usual tone from the telephone speaker. Sometimes it goes off finally (ding)after driving a few miles but did 20 today and it never came up. The turn signals will not work, or any of the other buttons in the car, sunroof, rear window shade, all controls on steering etc. Checked all fuses and I am baffled. Hopefully it can be an easy fix or I will take to Montana on next trip and see what it does at the Buffalo Jump State Park!! ANy ideas would be greatly appreciated.

Thanks.........Rick
