When I use the up and down arrows on the steering wheel, it only goes through all radio frequencies, instead of only the preset ones that I've programmed. I've looked through the user manual but cannot figure it out. I have this problem on both of my Benz's , yet I used to have a C-class that didn't have this problem. Anyone know where the settings for this is?

 

Go into your instrument cluster settings, and in one of the menus there will be an option for the radio.

Option 1: Frequency
Option 2: Preset

Something like that.

 

My settings only have 3 options:

Instr. Cluster
Lighting
Vehicle

None of their submenus have a radio option of any sort

 

My CLK has the NAV system and has those options, my C has the basic system and does not. What have you got?

 

My clk doesn't have Mac yet neither did my c.
