E. Gateway cannot be selected or any various problems

The factory installed external CD changer needs to be removed/disconnected from the car completely if you want to use all functions of the Gateway (music playback). This is because the Gateway emulates these functions, and the car can only work with one CD changer in the same time. If you don’t remove them, any various problems may happen like:

  • Volume changing automatically / randomly within 10-15 seconds or more
  • CD changer (Gateway) as a source can or cannot be selected but it reverts you back automatically to radio mode shortly (within 2-3 seconds)
  • Function buttons are not or only partly working (e.g. FFW)
  • Factory phone has no sound after iGateway installation or it has very low volume: section I
  • Error messages from the car
  • The Gateway or car radio resets, is not available at all

Volkswagen/Seat/Skoda: In some cases the car has MDI module instead of a CD changer. In this case the MDI needs to be removed/disconnected, and after that the Gateway could be selected as “Media in”. (Coding is mostly also required, please read section G!)
What is an MDI (Media Device Interface): The MDI is an external media device. It might have AUX, USB and/or iPod connection, that you can find in the glove box or center console mostly. The MDI device itself can be built together with these connections, or can be a separate unit too: you might find it where the connections are or behind the dash of the car.

Alternator noise or continous noise:

  • Generator noise is an extremely rare problem, it is a changing noise depending on the speed of the engine.  If it happens, it means there is an issue with the cable or the hardware. Replacing the whole package (Gateway hardware and its car side cables) is necessary. If the problem still remains, then there is a problem with the grounding of the car.

  • But if you can hear a constant noise, sometimes with periodic clicking noises, then the general grounding and shielding is not the best, and this is what you can hear. The cables can collect these noises as the cables and the Gateway are analog based. Please try to disconnect some of the cables, some cases unplugging the 30pin iPod Dock cable can solve this alone.
