#The18-year-oldAutoUpgrade

If there’s anything we’ve learned with this project, it’s something we should have already known but tend to forget: Most projects turn out bigger than first imagined, and some are so large as to be either impossible, or not such a good idea after all — at least for those without the proper tools or knowledge.

Such was the case when we went to install the Advent LDWS100 Advanced Driving Assistance System. This is not to say the Advent isn’t a good device. Or to say that it is. It’s simply to say that we couldn’t get it working, so we don’t know.

If you’re looking for some electronic assistance backing your car but don’t want to mess with installing a rearview camera, a backup sensor system might be the solution.

Consisting of ultrasonic sensors mounted at the rear of the vehicle and connected to an audible alarm inside the car, a sensor system gives you a warning when you’re getting close to something behind you, typically growing more urgent as you get closer.

There’s no question a rearview camera can add a measure of convenience to the business of backing up and increase your margin of safety. Studies have shown a rear camera makes it easier to see small children, pets, or obstacles behind your vehicle that might be otherwise invisible using just your mirrors or looking out the rear window. And that goes double for pickups and other tall vehicles, which can have a blind spot as long as 50 feet to the rear. Adding a rearview camera can also make it easier to see and hook up a trailer.

Many new cars have backup cameras, and it’ll be mandatory equipment by the 2018 model year. For those of us without, the aftermarket offers plenty of choices.

If you’re looking for an inexpensive power inverter and don’t want to sacrifice a cup holder or other interior real estate, the Schumacher X114 might be just the ticket — as long as you don’t mind a bit of noise with your power.

Capable of putting out 140 watts of continuous power, the X114 has more than enough juice to drive a laptop or other small electronic device. To that end, it comes equipped with one 120V receptacle, and a 2-amp USB outlet for charging a phone, music player, or most anything else that can be charged via USB.

Some of you have asked us to tell you more about the Acura that inspired this series about updating an older car with new tech. I’m more than happy to oblige, especially if doing so might inspire one of you to tender an offer.

A windshield head-up display, or HUD, is a beautiful thing. Capable of displaying navigational guidance, vehicle speed, and other information on the lower part of the windshield and in the driver’s line of sight, HUD systems have become increasingly common on new cars since their first appearance a couple of decades ago.

More recently, a handful of aftermarket suppliers and startups have gotten on the bandwagon, offering devices that pair with a smartphone via Bluetooth to provide similar functionality, even if these devices lack the seamless integration of a factory system.

Even if your car is equipped with a built-in power port or two, it may not have enough outlets to support all the electronic devices and habits of you and yours, or said ports may be inconveniently located or accessed. Maybe you want a configuration your car doesn’t have, like a 120V outlet to power a laptop or portable DVD player. Or maybe whatever ports your car has just haven’t been quite right since that last Big Gulp incident.

If any of these scenarios is the case, a power inverter can be the solution. Depending on the make and model you choose, an inverter can give you the versatility to power several devices at once, juice up your laptop or other electronic device, or provide more power and quicker charging than built-in ports in your car. And with prices starting at less than $50, inverters are affordable enough to make sense for almost any budget.

Safety experts generally agree that shutting off your phone altogether while behind the wheel is the safest way to travel, but the reality is that just isn’t going to happen for many drivers. In spite of thousands of deaths and close to a half million injuries chalked up to distracted driving every year, we are a society largely addicted to our phones.

But experts also agree going hands free is a safer option than handling a phone on the go, and most newer vehicles now have Bluetooth so drivers can keep their eyes on the road and use voice commands to make and receive calls. While arguably still distracting, hands-free calls are a better idea than punching keys at highway speeds, when a car travels the length of a football field in about five seconds — coincidentally, the average length of time it takes to read or send a text message.

For owners of vehicles without built-in Bluetooth, there are all kinds of aftermarket solutions available, from small units with a microphone and speaker that clip to a sun visor and cost as little as $20, to replacement head units that will set you back hundreds of dollars or more. For the purposes of this exercise, we looked at the former for their ease of installation and low cost.

With the average age of cars on the road now on the far side of 11 years, the latest electronic safety and convenience systems don’t do most drivers much good. But the good news is that any car can be upgraded with many of these features, from blind spot warning to Bluetooth for streaming music and hands free phone calls. You can easily install most of them yourself, and for a lot less than making payments on a new car.

Our new series of articles detailing some of these features will take you through what products are available, how they work, and what they cost. We’re starting with nine products available from the automotive aftermarket provided by our sponsor eBay, who has also graciously offered up three $500 gift cards. We’ve independently made our product choices based on ease of DIY installation, popularity, favorable reviews from other sources and users, and brand recognition with websites and readily available customer support.

Oh, and we’re installing all these upgrades on a 1999 Acura TL with 152,000 miles.

First up, let’s keep it simple: a trick phone mount from iOttie, the Easy One Touch 2.
