W124 Radio problem?

[lpozzo]

Hi,

I have a 92 300e that has the stock radio. Each time I turn the radio on, the volume goes to the maximum level and it does not remember the previous level setting. Also, once I select the presets, it goes to that radio station but then after a while the display changes the frequency numbers but the preset station remains.

I changed the radio with another stock radio and the exact same thing happens. I noticed that the presets were the same as my previous radio. Are the presets and volume level stored somewhere outside of the actual unit?

I truly appreciate your guidance. Thanks.

Best Regards,
Louis
