The GPS problem is now fixed, but i have another question.
The sound trough bleutooth and AUX is very low. I have to turn the volume knob from the car all the way open to get decent sound.
Is there a way to be able to set the volume more powerful from de M2C box? It is now at max allready (says 15 on the screen, and 100%).
The volume from my phone is much more powerful so it must be something in the M2C that is holding it back?
