It will probably be a little bit more money than that, I sent an email to the dealer today asking for an estimate. Mazda is offering to upgrade the car infotainment systems (aka, car stereos) on older model years for a fee. This is for a 2017 Mazda 3 hatchback. The idea of having gps screen showing up on the car system rather than the Android phone is appealing. By the way, I heard it is free on 2018 models just in case there are any 2018 Mazda car owners reading this.
