T. No sound only control on BMW

This problem could appear on 2 specific cases:

  • The car has DSP
  • The iPod Dock cable is not connected or wrongly connected

DSP: If the car has DSP, the Gateway is officially not compatible, due to limitations of the Gateway device. DSP systems require a digital input but the Gateway provides analogue so in those cases there will be no sound, only control. Having a DSP option is rare, there is no label on the radio. You can tell if you check the Tuner. If you see a coax connector, then it must be a DSP based system, but a service station can also help you to find out if the car has DSP or not.
Alternatively: If the car has DSP, and you still prefer to install the Gateway, then you can use a DSP analog-digital adapter (for example Blitzsafe).

iPod dock cable: On Gateway Pro BT there are two 9 pin connectors. The left one is dedicated to the 30 pin iPod dock cable, 2
nd one goes to the Connector port (if the installer / user ordered that piece separately).

If the cable is connected to the wrong place then no sound will be audible and the iPod / iPhone device will not be recognized properly.

 If you have no sound both from USB and iPod / iPhone too, then the problem might be related to the car specifications (DSP) or there is a conflict with a factory installed device (CD changer or else). The car harness of the Gateway device can also be plugged in wrong, or it may be faulty, please double check if it fits correctly.

So please check the following:

  • The installation
  • Car specifications (DSP not supported)
  • Make sure that there is no device which conflict with our module (CD changer, MDI), these needs to be removed from the car completely
  • Check all Gateway source options if possible with more music devices (iPod / iPhone, USB, AUX) to find out if the problem is related to one source device only or not
