I have an apx 8500 trunked system that is jumping tower sites every second due to a noise issue from a bluetooth system on a vehicle. We know this is the problem but to diagnose if its a location issue we need to see real time tower site locations to see if moving the device makes a difference. Is there a way to show real time tower site on the keypad instead of using rssi or site search that only displays for a second and disappears? We are using the E5 control head also. The problem it is causing is it is causing the audio on long RX to cut out as it is switching tower sites during the change.
