If your car radio has stopped working, or maybe you just want something newer than what came in your car, you might be interested in finding out how long it would take to get the radio replaced.
It depends on whether you are planning on trying to install the radio on your own or have it installed by a professional. It also depends on what kind of car you have and how difficult the installation process is.
DIY Installation
If you are looking to install your radio on your own, it might take you longer than if a professional were to install it for you. This is because you are likely learning as you go, so it will take you some extra time to be sure everything is in the right place.
It should take you anywhere from two to four hours to complete the installation. This will depend on what kind of car you have and what the system looks like when you get the manufactured radio out. Some cars require more work than others because there are more wires and pieces necessary.
You will also need to make sure you have every piece of the radio that is needed for it to work. This includes things like the wire harness, dash kit, installation tools, and antenna adapter.
It is extremely important to note that you will need to disconnect your car battery completely before getting started. This is to ensure that you don’t accidentally electrocute yourself when you are touching the wires.

Professional Installation
Professionals work on cars constantly, so they know exactly what needs to be done to install a new radio in your car. They are trained to install radios on every kind of car, so they know how much time will be needed based on their skills.
In most cases, it will take a professional anywhere from 30 minutes to one hour to complete the install for you. This is less than half the time it would take for you to install the radio yourself. However, with the convenience comes the cost.
If you are wanting a professional to install your radio for you, then you will need to be prepared to pay the price. You are paying for their experience, as well as all of the materials they will be using. If this is not something you are ready to do, then you might want to consider installing the radio yourself to save some money.
An important thing to note with a professional install is they often come with a 12-month warranty for the new system, which is something that both Halfords and Best Buy include.
