It has been couple of days that I am having issue with the system. There is a strange echo when playing my music. This happens with Bluetooth and playing it locally from flash drive.
I have tried the following so far
1- Deleted personal data from the head unit
2- Deleted my phone and connected back
3- Replaced flash drive
4- Already did the software update for the head unit last year
It seems that when I level the sound to back seats or driver side, the echo goes away. When I level it to passenger side or center, the echo comes back! Does this mean one of my passenger side speakers is bad?
Any help will be appreciated
