Please make sure that the CK11 is not in a position that will hinder your driving. The CK11 comes with a clip that allows you to secure it to your car's sun visor.
Step 1: Inserting the Clip.
Slip the clip into the back of the CK11 at the groove.
Step 2: Secure to Sun Visor.
Using the clip, attach the CK11 to your car's sun visor. You can either have the visor flipped down or up. Find a position where it is still natural for you to use the buttons on the CK11.
