If your radio system is integrated to Tango Tango, there are many details that we can work on remotely to improve your audio quality.
If you suspect your problem is specific to your phone only, you can go to Settings – Call Settings – Volume Boost. You might find that adjusting this helps. Note that maxing Volume Boost can, at times, result in audio distortion.
There are a lot of settings that can be tweaked in the background so please reach out to us and let us help.
