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)
