I had this removed by the dealer (from a GLA) because I'm changing vehicles. I installed it myself while watching a video. Please check the website at the bottom for compatible vehicles. I used the following YouTube video as a reference for installation: This is a TV canceler compatible with vehicles equipped with MBUX (AR navigation). You can switch the function on and off using the steering controller's return key. 【Product Features】 ・Reliable quality produced in an ISO-certified factory ・Easy installation with P&P cables ・Clean installation without the need for an external switch ・Default operation setting function (you can set the operating status when the engine starts) ・Power LED / Canceler operation confirmation LED Installation video https://www.youtube.com/watch?v=0tOoNNAuS-s Product description https://www.altporte.com/product/tv-canceler/benz-neo.html?srsltid=AfmBOoosYJazteZdhed_8Pbq-5xaInNywRJ_dVWy-Fax2LD80mk3EN9u Thank you for watching.
