A car stereo is one of the key components of your car and can make a ton of difference to your driving experience. It is precisely for this reason that a faulty car stereo with a radio that keeps resetting can be a nuisance and must be fixed at the earliest.

You must be wondering why your radio resets when starting the car? You probably have. Well, there are reasons for this and once you identify the cause, you can work towards finding a solution.

Why Does My Car Radio Keeps Resetting?

Usually, your radio will keep resetting when its power supply is unsteady. It can also indicate a bigger problem in the engine or issues with one or many components of the head unit.

If you leave the car lights on for a prolonged period or leave the door open overnight, the battery may get drained and may eventually start causing problems with the radio. Either the radio will keep resetting or it will abruptly stop.

There are several issues that lead to this problem but fret not, one can easily find a solution once the exact cause is identified. Here are a few of the most common problems that you need to be vigilant about.

1.    Memory Wire Has Suffered a Malfunction

One of the more common reasons for the repeated resetting of your car stereo is a malfunction of the memory wire. The thin yellow-colored wire is the one that can lead to this issue. So, do not let its fragile and diminutive frame fool you!

This memory card is responsible for the connection and for setting the time and frequency for your radio while you are on the move. If anything happens to this wire, there are chances that the radio settings will keep resetting. Every time you switch on the car engine, you will see the radio at factory settings.

If you check this wire and it is not loose or broken, you may want to check the red wire (yes, there is a red wire in it also). As opposed to the memory card, which always has current running through it, this red wire gets power only when the car engine is turned on.

In a nutshell, if your radio keeps resetting to factory settings, you need to check the yellow and red cables for any faults and breakages. If you find an issue, you can fix the wire and get rid of the problem. To do this, you can cut the cord and twist it and re-attach it to the stereo.

2.  Fuse Issues May Be the Problem

The resetting of the radio is also dependent on the fuse which is responsible for providing the stereo with voltage. It is only after getting the energy from the wick that the radio works efficiently.

Any damage to the fuse will result in an unstable power connection to the stereo. When this happens, the radio settings will keep getting restored to factory settings and you would have to keep recreating your playlists. We understand that this can be quite a nuisance but the good part is that it can be solved easily.

So, if you are facing issues with the stereo, you need to check the fuse. Check the wick and ensure everything around it is well connected and that there are no instabilities.

If you check and find issues and fix them, the problem should be resolved. If not, you may consider replacing the fuse. This will ensure steady voltage and the problem will not persist anymore.

3.  Fault in Your Car’s Head Unit

Another common cause that may be behind the frequent resetting of radio is a fault in your car’s head unit. Please remember that the car’s head unit is the most important component in a stereo and even the slightest flaw in the wires and cables can lead to issues with your radio.

The head unit can have several issues that may be small or big. So, one cannot evade a thorough checkup. You need to check if all the wires are in place and the connectors are in good condition.

If you feel any connection is loose, you need to fix the tapes and wires so that the stereo has an uninterrupted supply of power. Once this power supply is restored, your radio won’t automatically reset when you start your car and you will be spared hassle and time.

If there is a major flaw in the headset, you may also need to replace it in some cases. So, it really is dependent on a case-by-case basis and one can’t be sure of the course of action beforehand.

4.  Power Issues and Engine Cranking

Cranking of the car’s engine can truly be a nuisance and it can test the patience of even the calmest driver. You must have noticed in the event of the cranking of the engine, your radio displays a warning sign. This is usually suggestive of the fact that the battery is low and then it gets turned off.

The capacitor inside the stereo can be the issue for this problem. You may need to replace the capacitor with a new one to find a solution to the issue. A new capacitor will basically ensure a steady supply of energy to the radio and prevent it from resetting every time the car is turned on.

5.  Overheating Is Never a Good Thing

The overheating of the head unit is never good news and may give a lot of trouble to the car owners. Either there is overvolting of the system or your head unit is not cooling properly and as frequently as it should.

You need an experienced person or mechanic to check this issue for you. Once you have identified the issue, you need to get it resolved as soon as possible.

How Do You Stop Your Radio from Resetting Every Time You Turn Your Car On?

Now that we have told you some of the most common causes of radio resetting, you must be wondering how to solve this issue. There are simple solutions that can help you get the radio on point again. The best part? They aren’t always expensive!

1.    Fix Overheating at All Costs at All Times

Overheating is never a good thing especially when it comes to electronic devices. The first thing you ought to do is to not let the stereo unit get overheated. However, if you suspect something is wrong, fix the wire by reinstalling it. You will be surprised to see what a big difference this small step can make to the issue at hand.

2.  Vent the Stereo Unit Regularly

This should be done as a general rule of the thumb and not when you start seeing issues with the radio. If you vent your stereo unit regularly, you will only prolong its shelf life. It is essential to maintain the airflow through the vents so that your stereo system runs smoothly.

3.  Consider Battery Replacement

A slightly more expensive and also long-term approach to fixing the issue of radio resetting can be battery replacement. New batteries are supremely efficient at solving this issue and a host of other issues that pop up in vehicles and electrical devices at large.

4.  Replace the Head Unit

If nothing you have done is able to fix the issue at hand, your last resort would be to replace the head unit. But try it only after checking the fuses, wiring and battery.

The reasons for replacing the head unit can be an internal fault or if it is too faulty inside out. Sometimes, you won’t be able to replace all the elements in the head unit because either they are unavailable, have become dated, or are too complicated to replace.
