Just purchased a 2010 speed 3 with nav. I do not have the Nav Sd card nor do I really care to have outdated nav. Is there any way to buypass the system go get rid of the contact dealer message on the screen? Mazda dealer said the chip was $400.

Also I have no audio in the car. I check for power, ground and remote turn on to the bose amp and all were good so im assuming I need a new amp?

Why don't you take the opportunity and swap out your factory head unit for a new one that has CarPlay? That way you'll have a functioning unit and navigation that is always up to date. You can also then ditch the Bose amp and speakers and upgrade to nicer equipment for less than the cost of fixing/replacing yours. Just a thought.

Because I want the car to remain stock and dont use apple products. I just want the screen to show car details is it, very simple, very cheap.
