Hello together, I have a problem with my car radio. My Kennwood KDC BT50 U (in itself a really good radio!) does not recognize my Galaxy. With my old Sony Ericson it worked without problems. Now I wanted to update the firmware times because this was the first thing mt came to mind (and the first SChritt you should do). My problem with this: I can’t get any further when installing the firmware. It starts with this: In the guide you need a “Lapt op with Bluetooth or Bluetooth dongle”… my can only WLAN. Is there no way for an installation on n USB stick? Or has here by chance jmd. ne instruction ready? I am unfortunately the total Noob. Thanks in advance for all the answers. LG André
