Is there any way of making the microphone louder on these? I've messed around in factory settings to no avail. Oddly if an external microphone is used as opposed to the one built into the unit the volume someone on another phone hears is actually less.
One of the problems with these things seems to be there are very few settings you can alter.
The radio graphics on the one in the instruction book is totally different to the one on mine but no obvious way of changing it
