Not only will it help you with shopping, but more so, assure you that the unit you are getting is reliable and not a cheap knock-off. Below is a basic checklist that you may refer to when choosing a unit. Hopefully, this can help you get the best speedometer for you.

1. Quality and Warranty:

As with many other things, it is truly necessary to do a quality check on the model you are eyeing. And how are you going to do this without purchasing? Read. There are a lot of reviews from users that you can find on the internet. You can also interview those who already have an experience on the brand or model. This will not only give you first-hand knowledge from actual users but can also dig deeper on things that you may have doubts about. It is also advisable to know beforehand the unit’s rules with regards to its warranty so you will know what service they offer should you find yourself with a defective unit.

2. Features:

Not all aftermarket speedometers are created equal. Some are basic, while others are packed with features. It is great if you already have set your mind to what you want out of a speedometer since it will narrow down your choices, but it won’t hurt also if you go shopping with an open mind. You may never know such feature exists until you see a product that has it.

3. Price:

Speedometer prices usually vary because of the design or the features it has. Brand name also has some influence over the price tag. It is best to know how much you are willing to spend over such unit and what features are non-negotiable. Set a budget beforehand so you will not go overboard. The best speedometer should be within your price range and should not hurt your wallet.

4. Design:

This is one factor that many people fail to consider, but over time reveals itself as an important determining factor. Always keep in mind to get a speedometer that works well with your vehicle’s layout. All its features will just go to waste if it will block your view of any side of your car. It should also be just the right size for you—not too big which can cause a distraction, or too small either that you can't see its display.

5. Compatibility:

Are you planning to use the unit in different cars? If yes, then it is best to check if the unit you are eyeing is compatible with all the possible cars that you will use it too. Though most aftermarket speedometers are compatible with almost all brands or models, it is still best to check if it truly fits your vehicle. You can check with the manufacturer or your sales associate what works best with your car.

Installing Your Aftermarket Speedometer

Since speedometers are pretty much a straight forward product, they should be relatively easy to install. Although it still involves some wiring works, but if you know your way with the electrical make-up of your car, then you can do the installation yourself as most units come with instruction manuals.

However, if you do not feel comfortable installing it or lacks the technical knowledge to do so, it is best to get in touch with a professional technician who can do the work for you. This will ensure that the unit is properly installed and working, and all wirings are correctly placed. Whichever way you go, it is necessary to follow exactly and correctly the installation process to avoid any future problems with the unit and your car.
