It’s a common sight in the farming areas of the world — a group of enterprising automotive hackers take a humble economy car, and saw the roof off, building a convertible the cheapest way possible. Being the city dwelling type, I always looked on at these paddock bashing antics with awe, wishing that I too could engage in such automotive buffoonery. This year, my time would come — I was granted a hatchback for the princely sum of $100, and the private property on which to thrash it.
However, I wasn’t simply keen to recreate what had come before. I wanted to take this opportunity to build a solution for those who had suffered like me, growing up in the confines of suburbia. Surrounded by houses and with police on patrol, it simply isn’t possible to cut the roof off a car and drive it down to the beach without getting yourself in altogether too much trouble. But then again, maybe there’s a way.
The goal was to build the car in such a way that its roof could be cut off, but remain attached by removable brackets. This would allow the car to be driven around with the roof still attached, without raising too much suspicion from passing glances. For reasons of legality and safety, our build and test would be conducted entirely on private property, but it was about seeing what could be done that mattered.

Why auxiliary audio inputs haven’t been standard on automotive head units for decades is beyond us. But you can bet that if you’re looking at a low-priced sedan you’ll need to buy an entire upgrade package just to get an audio jack on the dash. [Jon W’s] Hyundai Sonata didn’t have that bells-and-whistles upgrade so he decided to pop his stereo out and add his own aux port.
A big portion of this hack is just getting the head unit out of the dash. This is made difficult on purpose as an anti-theft feature, but [Jon’s] judicious use of a butter knife seemed to do the trick. He lost some small bits along the way which were recovered with a Shish Kebab skewer with double-stick tape on the end.
With the head unit out, he opened the case and plied his professional Electrical Engineering skills to adding the input. Well, he meant to, but it turns out there’s no magic bullet here. The setup inside the unit offered no easy way to solder up an input that would work. Having done all of the disassembly he wasn’t going to let it go to waste. [Jon] grabbed a nice FM transmitter setup. He wired it up inside the dash and mounted the interface parts in the glove box as seen here.
It’s nice to know we’re not the only ones who sometimes fail at achieving our seemingly simple hacking goals. At least [Jon] was able to rally and end up with the functionality he was looking for.
