Will Auxiliary Louder Increase Your Car Value?

If your car’s stereo doesn’t; have Bluetooth or a USB port to connect your device, then you have to go for auxiliary input to enjoy these episodes. Also, adding this solution will increase the price of your automobile in the market as old models are now very much in demand.

What’s the Difference Between Aux vs. Bluetooth?

Aux describes any secondary audio connection, but most commonly refers to the 3.5 mm headphone jack. The technical term for this type of Aux connection is TRS (Tip, Ring, Sleeve) or TRRS (Tip, Ring, Ring, Sleeve).

It’s because Aux cords are time-tested that they remain so common. Aux cords are not without drawbacks, but the simple analog convenience is one reason these cords are popular. That said, Bluetooth is catching up.

The motivation behind Bluetooth was to come up with a faster, wireless alternative to the RS-232 serial port connection in the 1990s. The serial port was largely replaced by USB  by the end of that decade, but Bluetooth eventually found its way into the mainstream.

Since Bluetooth allows for the creation of mostly secure, local, wireless networks, the technology can be used for more than listening to audio. Bluetooth is not a one-to-one stand-in for a 3.5 mm headphone jack. Each standard has its core use cases, but as media becomes more wireless and digital, the case for Bluetooth becomes more compelling.

In case the car is of 80’s or 90’s or vintage model. Either way, if you are a fan of the podcast and want to groove with your favorite episode while driving, you need to input an auxiliary port to connect your digital device i.e. your phone/tablet/iPod/Mp3 players, etc to your car stereo for good sound quality and easy portability.

If you want to add an auxiliary/USB port solution to your existing setting, it will cost you 80$ for aftermarket solutions. If you want to go for factory kits, it will cost you approximately 200$ give or take.

In case you are going for premium kits can cost you as much as 800$ excluding the cost of installation. Some providers have a free installation service available. Buying from such a provider will be a good choice.

The price will depend on the head unit that your car has. The head units in these models are rather old and this causes the installation price to go high. Typically these units don’t have a USB port nor a port to connect your auxiliary cable so you need to input one in your stereo.
