I'll give GM one thing. The base, stock radio in my new Malibu is the first factory radio in quite a while that I did not want to immediately tear out and replace. Monsoon, Bose, Mach 460, Mach 1000...they all needed to die. I've got a pretty good sounding car audio system that is currently installed in it's third vehicle. Last time I swapped it over, I just replaced the head unit to update for Bluetooth.
And yes, I've had some pretty awful home systems over the years that could be blown away by some of the new, modern car systems.
