I-Pilot ?

How do you erase a "track" you have recorded? I know that you can record up to 3 tracks but if you want to record a 4th what then? Are you simply recording over one of the previous tracks? If so how do you determine which one? In advance thanks for any help or insight.

You just record over it. When you hit the record button it will flash the letter A to change hit the + button to change to B or C. You will have to remember which track is A B or C
