 mazda had a large number of complaints about the upgraded stereo, there was even an online petition about how bad this head unit was maybe the petition was turned off after 4000 signers, They stuck it right back into the 2015 model same problems. The thing is so bad that the unit is no longer in the 2016. I Have to crank my neck so much just to get into it , I how had a sore neck constantly. The AC vents for the driver are so badly placed that they are great at cooling your left wrist and right forearm but can't hit your face. They have also changed that on the 2016. The Ac unit is only so-so in the Arizona desert it can take 10 miles of driving to really feel like the car is cooling down.  Traded the car in lost $9000 in value in one year. Hated the car. Will never buy a Mazda again.  Tried them 3 times bad to only so-so cars. Bought a Scion one made by Toyota not Mazda.
