The luxury of owning multiple old cars has led me down an interesting path - to create a modern radio system that caters to my nostalgic cravings while addressing some common shortcomings of current Bluetooth-based solutions. I'll be building a custom radio unit with features like FM radio, Bluetooth connectivity for hands-free calls and navigation, auxiliary input for external devices, and even DAB+ functionality. But here's the twist - I won't be using pre-made, high-end components that compromise on design or cost. Instead, I'll opt for more affordable options and DIY it myself, leveraging popular breakout boards like the Si4703 Radio FM RDS RBDS Tuner Breakout Board and a F-6188 Bluetooth module. The result will be a unit that's tailored to my needs, with a focus on functionality, simplicity, and even a dash of vintage charm. Will I succeed in creating the perfect retro-modern radio system? Only time (and a healthy dose of DIY expertise) will tell!
