Please check the following:
- installation
- car specifications (DSP is not supported on BMWs)
- make sure there is no device to conflict the Gateway
- check all sources (iPod/iPhone; USB) to find out if the problem related is to one source or all
G. Factory phone option does not work
The Gateway Pro BT can operate as a Media player (Gateway functions are active only) or a phone
module (only on CAN BAP – GWP1V21). In order to turn a main function OFF (phone or media), you
need to use the DIP switches on the hardware.
To disable phone functions, DIP switch #5 needs to be turned ON.
To disable Media function on BAP, you need to turn DIP switch #6 ON.
After setting DIP switches, always press reset on the device so that it will boot with the new settings.
To use the Gateway Pro BT as a Media player
- Disable the phone option (DIP #5)
- Change the 4 PIN MOLEX (phone audio cable) installation on the Gateway harness. If you miss
that step, the factory phone will work but no sound will be heard.
Please note: The factory phone module and the Phone option on the Gateway cannot be used parallel.
One of them has to be disabled/disconnected.
H. A2DP function is not available in the Source menu
If there is an older firmware version on the Gateway it is possible that you need to enable the BT audio
option in the Gateway menu. To do this, you can follow the procedure below, however it is highly
recommended to update the Gateway firmware to the latest version.
To activate the A2DP functions:
a. Initiate the Gateway menu. This is car dependent:
1. BMW: you need to press/select Disc 6
2. Audi: press menu button on the SWC
b. Select ‘Settings’
c. Select ‘BT Audio’
d. Set the option to ‘ON’
e. SAVE (on BMW you need to press and hold the FFW button)
f. Turn the whole system OFF wait for 2 minutes
g. Turn the system back ON (now the phone will pair with BT audio option also)
h. Go to Source and select BT Audio
