You need music! NOT “CHECK ENGINE” Nightmare
I’m Westley (aka Gizmo Guy)—yep, that guy from the YouTube videos.
That is me in early 2000 with family’s S-Class and E-Class
Amazon FM transmitters SUCKED!
I wanted streaming music in my old Mercedes, but I absolutely refused to tear out my classic cars. To solve my own problem, I engineered this Bluetooth for factory radio specifically for 1998–2012 Fiber Optic Audio systems. It offers crystal-clear, CD-quality sound for hands-free talking and streaming Spotify, YouTube, and Waze—without gutting your future classic. It worked so perfectly, I knew I had to share it.
