Hi all,
I didn't buy a nav card for my new 2021 Mazda 6 Carbon because I heard you can save a few hundred dollars getting them online. Can anyone point me in the right direction as to how? And, if I get a chip online, will it still show turn by turn on the heads up display? That's one of the 3 reasons I want one. (The others being that my phone could die, and that I'm not in love with Android Auto.)
