Any suggestions about a month ago the sound on my stereo started
going of as i hit a bump and came back on as i hit another bump etc
and slowly got worse to the degree i wil have no volume for two of three
days and all of a sudden it will come back, the rest of the system is working
IE the display screen/Sat Nav and TV still work there is just no volume.
If i switch to the TV i have a mute message on the screen so the system
seems to know there is no volume, can anyone help
