This has been my experience with FCA dealers, you truly have to be an informed consumer now. Without the help from this forum you would of been getting a run around.
Hopefully this will help you, I know you have been heated about the stereo(rightfully)
It seems that the customer service from a FCA dealership is so hit or miss. Its hard for me to figure this out. I have owned Toyotas majority of the time and with being AD Military I have moved 7 times in 8 years. Every Toyota dealership has been about the same on Customer Service(ex. performed TSB's and Warranty work on Oil changes with me ever asking or complaining about issues).
My ordering experience between 3 dealerships with this truck has seemed to where I just needed to grab their computer and do it myself. Luckily the 3rd dealership was awesome and for sure worth the extra 20 min drive.
