Since my USB port doesn’t work (doesn’t recognize and charge a connected Android smartphone) my question: Can the current SW 1890 update you via the SD card slot? The installed SW of the SLDA is still the original version 0840-151203 I already have the SW 1890 on a USB stick and could also copy it to an SD card. Maybe the current SW then recognizes the Android smartphone connected to the USB. The friendly wants me on Wednesday a new USB port in the Install the center console compartment because it suspects that the existing USB port is defective, because it does not even charge the phone. However, it said directly that it cannot give any guarantee that everything works with the new USB port.
