How do you preset radio stations on a 02 Saturn SL? I have tried tuning to a selected station and holding a preset button for 3-5 seconds and it doesn't work.

If it is aftermarket, some one might not have hook the memory wire up. But most will preset, it will just be lost when you turn off the car. If it is hooked up right, after market or factory, it is an internal failure. Replace the radio.

Station preset on AWR1-1W bose radio

I found out you tune the radio to the station you want to preset, and hold the preset button (1-6) that you want to assign it to until it beeps. And it's set.

Memory loss

you need to remove the radio and swap the red wire for the yellow wire and vice versa, they have bullet connectors to allow you to do this, basically the permanent live and the ignition live are the wrong way round.

Check the stereo installation.

There is a YELLOW wire that needs to be connected to a Constant +12 volts when the vehicle is OFF.

It is responsible for saving the pre-sets after the engine is off.

Best of Luck.
