Just picked up an R7 and trying to decide if I want to keep it. One little issue is that the voice alert is much quieter than the actual radar alert, to the point I can’t hear/understand it. Is there a way to separately adjust this volume?
Make sure you have the newer Firmware that has an increased overall volume.
Also make sure the auto mute isn't what you are experiencing. You may want to turn that volume up. It is separate.
