Why can the aftermarket radio forget the saved settings?

Model: (Various brands) Various
Part: Car stereo

Video tutorial

A problem that can often occur is that aftermarket radios "forget" the saved settings. The YouTuber explains the reasons.

The first is that the radio may still be set in "demo" mode, which is the mode in which it is kept in the retail point for demonstrations in front of customers. The second reason could be the wiring.

Most devices come with standard wiring, where the wires we need to look at are black, red, and yellow. The black wire is the ground and must always be present.

If it has been cut, then there will definitely be problems. We should also check that the wires are connected to the correct colored ones (red to red, yellow to yellow); otherwise, it will never work properly.
