navi business aftermath
Posted Iguess in a wrong forum first time...
I'll get to the point... I tried to code something on the audio system of my E91 with Business Navigation CD M-ASK (02.2007) with a small display. However, I managed to "mess it up." The button that increases and decreases the volume no longer works as it should. Instead, it mutes the volume regardless of whether I turn it left or right. When I press it, nothing happens, but if I press it while rotating, the CD ejects. The CD eject button no longer works, nor does the left-right button. Do you have any idea how I can fix this issue? |
