I am new to the site so if this is in the wrong area I apologize.
Long story short...
I took my 2008 WRX with the Navigation set up into a car audio shop to have an amp installed and upgrade the factory speakers. After all of that was said and done the "beep" sound selecting menu items and navigation voice is so loud it is unusable. This is the case whether the stereo is in use or not.
Any ideas as to what happened? They told me that no volume levels where adjusted and such...I call the local Subaru dealer and they couldn't provide any info either
I have checked the levels and nothing changes at setting 1 or 10. Are there any physical settings on the actual nav system I am missing? Perhaps a volume adjustment on the back of the unit?
