So I went ahead and bought myself a new Canyon, regular cab, SLE level trim. GMCanada website specs show the SLE trim wit a 6 speaker stereo. The on-line configuration tool shows a 6 speaker stereo. The quote emailed to be by a different dealer than the one I bought from showed a 6 speaker stereo. The US site also shows 6 speakers.
The truck has 4 speakers.
The dealer says that's all it is supposed to have.
What's the best way to approach this? Now it's a matter of principle.
