Troubleshooting guide

Gateway Pro BT support issues
25
I. CDC not removed properly (CD-Changer is still present on iBus)
On BMW, it happens quite often that they forget to disconnect the original CD-Changer properly.
Please note: The installer needs to disconnect all cables physically at the CD-Changer (2 separate
wires), otherwise they will experience strange issues like:
- Volume changes automatically/randomly within 10-15 seconds
- CD-Changer source can or cannot be selected but even if you select it, you are back to
radio mode within 2-3 seconds
- Function buttons are not or not fully working (e.g. FFW)
- You cannot enter to the Text mode selector menu
J. Factory phone is connected
Those Gateway devices with integrated phone option, do not work properly together with factory
phone modules. So it is not possible to use our device only for having BT Audio (A2DP) and use the
factory option for HFP.
Removing the factory phone is highly recommended. Else the phone function has to be disabled on
the Gateway.
K. Activation on VW – Media and Phone (GWP1V21)
The Media option is disabled on most CAN BAP based systems (VW – GW17V21), therefore it has to
be coded before or after the Gateway installation. The procedure is not difficult (takes 10 minutes
approx.), the vehicle needs to be taken to the VW service and the ‘Media Player 3’ option (2E) has to
be programmed using a service computer.
In order to have phone option on the cluster display too (MFA High Line or Maxi Dote is required) you
need to program ‘Phone’ option (77) too using a Service computer (Autologic or VAG-COM). Having
that option coded on RCD/RNS 310 (called Swing and Amundsen in Skoda) is essential for the phone
menu is available on the cluster display only with these radios.
L. How to generate the GW_EES.BIN file:
The GW_EES.BIN file provides important information regarding
- the exact firmware version
- the basic settings (text, or car configuration)
- connected devices (like DAB+G)
To generate the file you need to have a simple USB thumb drive which is
- formatted to FAT 32
- has only one partition
- has at least one playable music content on it
You need to
1. Power the system ON (radio, ignition)
2. Connect the USB drive to the Gateway (it starts to operate)
