Setting radio stations on 2009 clk350

most work like this turn the knob to the desired station , press the pre-select button and hold in until it is saved
then turn the knob to another station and hold in a different button until it is saved and so on until you have all of the stations on the pre-select buttons

Hi Nick,

Your radio might save the bass & treble settings with each station. Try choosing a station, set the bass, treble and any other variables (mid-range, etc.) and then SAVE the station to a button. Do this for all of the buttons / stations you like.

If this doesn't solve the problem, tell us about the radio (AM/FM/Cassette/CD and Factory or aftermarket - in which case we'll need to know the make and model of the radio.

If radio has save button then tune your station push save button then push a number on preset you want it saved to. The radio automatticlly stores the strongest station in your area.

disconnect battery with key off ! and set for 10 min. then rehook up battery and check radio, might take care of it !

If you have buttons on your radio that allow you to switch stations, it generally is simply a matter of pressing and holding the button in place for 10-15 seconds. The year, make, and model of the vehicle doesn't say much, as vehicle may have an aftermarket radio. Just find the station you want and if there is a are button presets, just push and hold it in. On most of my cars, old and newer that I have owned, confirmation of the setting is generally accompanied by a beep. Good luck! JD

Hold down the one of the numbered buttons (1-6 I think) at the bottom for 3-5 seconds while listening to the radio station you want to save. You should hear a beep, and the station will be saved.

Station Pre Set:
You can save 4 pre sets on this radio (1-4) tune the radio to the station you want to save then PUSH and HOLD one of the pre set butons until the sound returns, the station is saved to that pre set. Repeat for the 3 presets.

Clock:
Hour: Push and hold the CLK button and at the same time push the SEEK button to adjust. < decrease hours > increase hours.
Minute: Push and hold the CLK button and at the same time push the TUNE button the adjust. < decrease minutes > increase minutes.

Not many I've seen do, I guess because if you delete it, what does it delete to?
