I have the same unit avn30d. No problems.
I have the e brake hooked up its also hooked up to a switch so it runs dvd's when driving(and use gps functions)this way it can be shut off quickly if needed.( a crash,pulled over by cops ect)
The installer said " I didnt hook up the switch" to cover them from liability
There is a button for louder volume when driving, for the gps.(it raises 1 level when driving on highway)
My on star volume is just right.
