My device is an in car system running Android 6.0.

I have always preferred iGP Primo to Nextgen but have problems with the volume control.

I have now installed, in the root directory, iGO Primo 2.4_9.6.29.636868-iGO Fast Ultimate.

The master and voice volume control cannot be set within the program, only by the device volume control. If running the radio or music with the navigation also active the sound output on navigation is lower then on the other functions, and as they both alter with the device volume control you cannot therefore here navigation instructions.

Is there any way to reintroduce the inbuilt volume control for iGO?

Secondly, although there is a facility to mix GPS sound with device sound to enable the device sound to lower when GPS commands are spoken this does not work with Primo. It is perfect with Nextgen.

Is it possible for this function to work within Primo?

Answwers will be appreciated and noted.
