I operated a A40D for 4 years along with various others,I learned something about it,does all volvo haul trucks incorporate what I call sub commands and why isn't common knowledge with operators
The company i work with just got 3 brand new A25G. I spend 8h every day in it. And i cant belive how bad the speakers to the stereo are....... rest is very good.
All factory audio is junk, unless your paying twice the worth for a factory jbl system or something like that...BUT last time i checked speakers and radios aren't hard to replace
