Hey, can anyone help me? I use to have a C300 2016 where I plugged in an external hard drive into the USB in the centre arm rest storage area. The hard drive was loaded with movies. I could play any movie on the hard dive (when the car was not moving) on the comand screen via media external sources options. I just got me a new E350 2019 and plugged in the hard drive (used in the previous car) but the comand is saying it is not recognised. I tried reformatting the hard drive but still no joy. I put the movies on a SD card and tried that and it worked so it is not a comand issue, must be something I am not doing right with the hard drive (I think). How can I get the hard drive to work - what am I doing wrong Can anyone help me please?
