The original audio system of the Mercedes S-Class W220 does not support Bluetooth music streaming, only phone hands-free, and often with outdated technology. The simplest and most economical solution is an external device that connects to the cigarette lighter; the smartphone connects via Bluetooth to the transmitter, which sends the audio to a free frequency (for example, 88.1), and then you just need to tune in to that same frequency.

If our S-Class has an AUX jack, the solution is even better because you just need to connect with an AUX cable, power the transmitter with a USB to the cigarette lighter, select AUX mode, and pair the smartphone with the transmitter. We recommend the code B0DFH77PXC on Amazon for €15.99 with free delivery for Prime customers.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
