If you are using Foreflight with an iPad or iPhone, be aware that the audio portion of the Runway Proximity Advisor is available through the "i" device audio including BLuetooth if you have Bluetooth enabled headsets. If not and you have an intercom with Auxiliary Audio, it is possible to cable the pad or phone to that connection to get the same info. Be sure to check volume settings on the "i" device and the intercom and the headset to be sure the sound level is to your liking.
